Frequently Asked Questions - MX (2011) Zero

How long does it take to fully charge the Zero MX (2011) power pack?

Standard charging takes about 2 hours from fully discharged. Optional quick charging with an additional charger reduces time to approximately 1.2 hours for 100% charge or 1.0 hour for 90+% charge.

What is the estimated range of the MX (2011) on a full charge?

For the MX Dirt version, range is approximately 30-60 minutes of riding. For the MX Street Legal version, maximum range is 42 km (26 miles) or 35 km (22 miles) under EPA UDDS testing.

How should I store the power pack when not in use?

Always leave the power pack connected to the charger if storing for more than 7 days. If fully discharged, charge within 24 hours. If stored fully charged, recharge within 60 days. Failure to follow these guidelines may void the warranty.

What does the performance level switch do?

The two-position switch toggles between 'I' (softer acceleration, ideal for new riders or extending range) and 'II' (aggressive acceleration for advanced riders). The motorcycle must be stopped and key off to change the setting.

How can I check the power pack charge level?

The instrument panel has a charge indicator with colored segments: green (full), amber (low), red (very low). On X/MX Dirt models, it shows bars; on street legal models, it shows a battery level display.

What do the beeps from the power pack mean?

The BMS emits beeps for various conditions: a single 'OK' beep on startup, a beep every 10-12 seconds when power pack is low, and different error patterns (e.g., 2 fast blinks for high temperature). Refer to the manual for detailed beep sequences.

Can I ride the Zero MX in the rain?

The manual advises against outdoor charging in the rain but does not explicitly forbid riding in rain. However, it warns to avoid water exposure to electrical components. It is recommended to ride with caution and avoid deep water.

How do I swap the power pack?

Remove the key, support the motorcycle, unscrew the thumb screw (or security bolt on street legal models), pull the power pack rail away, disconnect the connector (if applicable), use the ejection lever, and slide the pack out. It weighs 20.9 kg (46 pounds). Reverse steps for installation.

What is the tire pressure specification for the MX?

For both MX Dirt and MX Street Legal, front and rear tire pressure is 103 kPa (15 psi). Check and adjust when tires are cold before each ride.

How do I adjust the chain tension?

Loosen the motor mount bolts, loosen the jam nut on the chain tensioner, turn the tensioner bolt a quarter turn at a time until free play is 32 mm (1.25 in) total, then tighten all bolts to specified torque (see Bolt Torque Table).

Vehicle Range

The range of an electric vehicle is defined as the distance the vehicle will travel on a single full charge of the power pack. Just like EPA mileage estimates on an automobile, “your mileage may vary.” Your range results are a direct reflection of your riding habits and conditions. The more conservatively you ride, the better range you can expect from your Zero motorcycle.

Some of the factors which affect range include speed, acceleration, number of starts and stops, terrain, as well as changes in elevation. The combination of these factors, as you travel from one point to another, defines your trip profile. In addition, tire pressure and payload are important considerations.

We suggest that you ride conservatively when you first get your Zero motorcycle and get to know your motorcycle. Once you become familiar with the range versus performance of your motorcycle, then you can adjust your riding characteristics if you so desire.

Optimizing Your Range By Adapting Your Riding Style

• Apply the throttle slowly and try to match the motorcycle's acceleration with your throttle position.
• Hard acceleration will decrease your range.
  •Coasting whenever possible makes a significant difference; the motorcycle will coast for a long distance (take advantage of this).

Public Charging Stations

There are more public charging stations coming on-line every day and there may be some in your area. You can charge from a public charging station with the optional J1772 Zero motorcycle accessory. These stations are often available at a variety of locations including shopping centers, city parking lots, airports, hotels, government offices, and other businesses. We recommend that you search the internet for locations in your area. For example, search for “charging stations.”

Emissions Information

The Zero electric motorcycle is a zero emissions vehicle under California (CARB), U.S. Federal (EPA), and European Union standards. It uses no gasoline or other liquid fuel. It has no tailpipe and therefore no tailpipe emissions. It also has no exhaust or evaporative emissions. Because the Zero runs solely on electricity, it is the only kind of vehicle which actually gets cleaner in terms of air pollution each year, as the electricity grid gets cleaner and more renewable.

Zero Emissions Vehicles (ZEVs) offer greater efficiency, and can help solve the serious air pollution, global warming, and energy security problems facing the country and the world.

WARNING! Please use only Zero approved parts and accessories for your Zero motorcycle. Parts and products for your Zero motorcycle have been checked and tested for safety and suitability. Zero is unable to accept any liability whatsoever for parts and accessories which have not been approved.

Transporting

When the front fork is compressed, the built up pressure must be released to help prevent fork seal leaks. There is a 3 mm Allen “bleed” screw located just in front of the rebound adjuster on each fork leg. This “bleed” screw (A) is used to release the built up pressure. Loosen the screw slowly, but do not remove. Once all the air is out, tighten the bleed screw.

When the fork is released, with no weight on the front tire, the screw must be opened again to allow for stabilization. Ensure that the screw is tightened before riding.

It is recommended that the motorcycle be tied-down using ratchet straps. Place the ratchet straps around a frame contact point. Soft straps must be used to prevent scratches or other damage.

Use two ratchet straps in the front and two in the rear. The tie down straps should be at a 45^ angle from the motorcycle. Follow the manufacturer's instructions for the ratchet straps you are using.

Safety Information

General Safety Precautions

1. This is a performance motorcycle and should be treated with extreme caution.
2. Proper safety gear, including a regionally approved helmet, riding boots, gloves, and protective clothing, should be worn while riding to reduce the risk of potential injury. We highly recommend the use of full height riding boots since the vast majority of motorcycle injuries are leg and foot injuries. It is not recommended to ride without the correct protective clothing; this applies to even short journeys, and to every season of the year.
3. Read all additional warnings and product instructions in this owner's manual, as well as safety labels, before operating your electric motorcycle.

4. Never carry a passenger. This motorcycle is designed for a SINGLE RIDER ONLY.

5. Never permit a guest to ride your electric motorcycle without proper instruction.

6. Never use alcohol or mind-altering drugs before operating your electric motorcycle.
7. Persons unwilling or unable to take responsibility for their actions should not use this motorcycle. You assume all responsibility while operating your motorcycle. The seller will assume no liability for misuse or operator negligence.
8. Prior to each use the rider must check everything in the "every ride" column of the maintenance schedules on pages 5-20 through 5-25, and the power pack function level as indicated on the instrument panel charge indicator.

9. Your safety depends in part on the good mechanical condition of the motorcycle. Be sure to follow the maintenance schedule and adjustment requirements contained in this manual. Be sure you understand the importance of checking all items thoroughly before riding.

10. Modifications to the motorcycle may render the vehicle unsafe and may cause severe personal injury. Zero Motorcycles cannot be held liable for non-approved modifications.

11. Be very careful when loading or adding accessories to your motorcycle. Large, bulky, or heavy items may adversely affect the handling and performance of your motorcycle.

Important Operating Information

1. Always turn the key switch and motor stop switch to the OFF position when not actively riding. It is very easy to forget that the motorcycle is powered up because it is silent. An accident can occur if the motorcycle is left powered up while getting on or off the motorcycle.
2. Switch the power OFF when backing up or pushing the motorcycle while dismounted.
3. Use the rear brake when you are stopped on an incline. Do not hold the motorcycle using partial throttle or damage to the motor may occur.

4. The power pack should be plugged in when storing the motorcycle for extended periods of time.

5. Keep your Zero connected to the charger when your motorcycle is sitting in storage or if it will be sitting unused for more than 7 days.

The power pack must be charged within 24 hours if fully discharged, and must be charged within 60 days if stored fully charged. Zero recommends you plug in your power pack after 7 days even if it is fully charged. Please leave your power pack plugged in whenever possible.

WARNING: Charge the Zero power pack with the Zero charger.

1. Always firmly apply the rear brake while turning the key switch ON or OFF. In the event of a malfunction, the firm application of the rear brake will help keep the motorcycle from running away.

2. The power pack does not require, or tolerate, deep discharging. To get the most power pack life, recharge each power pack immediately after each ride. Leaving a power pack in a discharged state will cause damage. See Charging The Power Pack on page 4-14.

3. Failure to follow power pack storage and charging instructions as described in this Zero Motorcycles Owner's Manual may void the warranty of your Zero motorcycle. These guidelines have been rigorously tested to ensure maximum power pack efficiency and service.

MOTORCYGLES

IMPORTANT

THROTTLE AND SPEED CONTROL

The fully electric drivetrain of this motorcycle is different than any gas counterpart:

• There is no engine braking and no engine noise
• When going into corners or coming to a stop you will be fully dependent on your brakes
• It is easy to find yourself speeding due to the absence of engine noise
  • Passersby will not hear your approach - be extra cautious when making turns, entering intersections or when people are likely to cross your path

Be aware that your motorcycle is still ON during stops and while at an "idle". Accidentally twisting the throttle can cause serious harm.

Please read the user manual for more information prior to operating the motorcycle.

A. Charge Indicator

The charge indicator on the motorcycle is used to inform you of the amount of remaining energy in the power pack. The charge indicator is segmented into 3 colors, the colors indicate the following:

•Green indicates a full power pack.
- Amber indicates that the state of charge of the power pack is getting low.
- Red indicates that the state of charge of the power pack is very low and that the power pack should be recharged as soon as possible. The motorcycle will soon cease to operate due to a critically low charge level.

B. Main Power Indicator

The green LED is solidly lit when the motorcycle is ready to ride. When the green power LED is on, do not twist the throttle unless you are ready to ride.

C. Motor Temperature Indicator

The motor temperature sensor senses the temperature of the motor and power pack. This will trigger the motor temperature indicator, which will blink in the unlikely event that you exceed the motorcycle's performance capabilities. See Motor Temperature Indicator on page 6-11.

D. System Warning Indicator

In the unlikely event you exceed the motorcycle's performance capabilities, the indicator will flash and gently oscillate the motor output to notify the rider. Back off of the throttle to reduce heat and eliminate the oscillation. Doing so will also eliminate the indicator flashing. If the red LED is flashing, the system has detected a fault. For troubleshooting, see section 6.

Performance Level Switch (X/MX Dirt)

The performance level is a two position switch that toggles between "I" and "II". To select either of the switch positions, the motorcycle must be stopped and the key switch in the OFF position.

The “I” position reduces the acceleration of the motorcycle to be less aggressive. It is an ideal position to use for times when you want softer acceleration. This position is also good for newer riders and for extending range.

The “II” position causes the motorcycle to accelerate at a significantly faster rate. This position is recommended for advanced riders.

Those who take advantage of the "II" position are likely to see a slightly reduced range.

General Operation

Pre-Ride Inspection

Before operating the Zero motorcycle, check the following to make sure the motorcycle is secure and intact:

•Power Pack

Make sure the onboard charge indicator is green, indicating a charged power pack. If the charge indicator reads below: X/MX Dirt - 3 bars (1/2), or X/MX/XU Street Legal - 5 bars (1/2), we suggest you recharge before use.

- Drive Chain

Check chain slack and condition. Adjust and lubricate if necessary. The drive chain must be cleaned and lubricated at the intervals specified in the maintenance schedule. Otherwise, it will quickly wear out, especially when riding in dusty or wet areas. See Drive Chain on page 5-9.

• Brakes

Squeeze the brake lever and press the brake pedal individually and push the motorcycle to see if it rolls. You should be able to completely lock-up the wheels by applying the brakes.

• Throttle

With the key switch in the OFF position, twist the throttle and release to verify that the throttle is smooth and returns correctly.

•Tires

Check both tires for condition and tread depth. Check cold tire pressure frequently. Check for damage and alignment. Maintain correct tire pressure as specified on page 5-9. Replace the tires when the tread height is 2 mm (0.08 in) or less.

CAUTION: Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation, "blowout," or unexpected loss of motorcycle control causing personal injury and possible death. See Tire Inflation on page 5-9.

• Electrical System

Power Pack

The battery is located within the power pack and requires no special break-in period. Under normal use and correct power pack maintenance, the power pack should maintain most of its capacity for approximately 5 years, depending on use. The charging time is the same if connected to 120 V AC or 240 V AC; this is an input to the charger. The charger output will be the same. The normal recharging time of the power pack is usually less than 2 hours in ambient temperatures. Out of the normal temperature range charging and run-time times will vary. The batteries should not be used outside of the range of -7°C - 71°C (20°F - 160°F); the Battery Management System (BMS) will turn off the motor controller outside of this range.

It is required that you leave the motorcycle on the charger if you expect it to sit in storage or unused for over 7 days. The power pack must be charged within 24 hours if fully discharged, and charged within 60 days if stored fully charged. Zero recommends you plug in your Zero motorcycle after 7 days, even if fully charged. Please leave your Zero motorcycle plugged in whenever possible.

The power pack should maintain up to 80% of its capacity for approximately:

•1,215 hours X/MX - Dirt
•47,000 Km (29,000 miles) X/MX/XU - Street Legal

WARNING: Opening of the power pack is for trained Zero Motorcycles' technicians. Please be aware that incorrect handling of a Zero power pack can be dangerous. DO NOT OPEN!

Add On Electrical Equipment

WARNING: Do not add anything electrical to your motorcycle unless approved by your CSC. Some electrical components can damage your motorcycle. Some add on electrical equipment can keep other components from working as they should or can dramatically reduce the range and/or life expectancy of the power pack.

Power Pack Swapping

The motorcycles feature a quick change power pack. This allows the rider to charge one power pack while using another. To change the power pack, perform the following:

Removal

1. Remove the key from the key switch and safely support the motorcycle.
2. Locate the thumb screw (A) (X/MX - Dirt) or M8 security bolt (B) (X/MX/XU - Street Legal). The security bolt requires the supplied tool to remove and install. The security bolt can be replaced with the thumb screw available from Zero Motorcycles Accessories.
3. Pull the power pack rail (C) away from the motorcycle, unhooking it at the front.
4. Disconnect the power pack connector (D) (XU only). See image on page 4-9.

1. Using the ejection lever (E) remove the power pack connector. See image on page 4-9.

Note: The power pack weighs 20.9 kg (46 pounds).

1. Using a firm grip, slide the power pack out of the frame.

Installation

1. Slide the power pack into the frame.
2. Connect the power pack connectors.
3. Install the power pack rail into the front slot first, then push the rear side into the frame.
4. Install and securely tighten the thumb screw/security bolt.

Battery Management System (BMS)

Every power pack contains a Battery Management System (BMS) which monitors the condition of the cells and optimizes the charging process to provide the highest-performance, longest-range, and longest-life for the power pack.

The BMS also monitors the power pack for a host of predefined conditions, and then takes actions according to these conditions. Some of these conditions are listed below. Also see Understanding Beep Sequences on page 6-3.

•Low Voltage

Action: When a low voltage is detected, the beeper is sounded to alert the rider that he or she should stop riding the motorcycle. This beeper beeps approximately once every 10-12 seconds when the motorcycle is being ridden and then once every minute when the motorcycle is inactive.

•Dangerously Low Voltage

Action: If the voltage drops to the point that may damage the battery cells, the power pack sends a signal to disable the motor controller and the motorcycle will not run until the voltage returns to an acceptable level.

•High Or Low Temperature

Action: If the BMS senses that the power pack is too hot, above 71^ C ( 160^ F), or too cold, below -7^ C ( 20^ F), it sends a signal to disable the motor controller and the motorcycle will not run until the temperature returns to an acceptable level. The charger will also be disabled in this condition.

•High Voltage

Action: If the BMS detects a voltage that is too high, it shuts down the charger to prevent over-charging.

The BMS is sealed inside the power pack. As a rider, you don't need to think much about the BMS - it just silently does its job as you charge, ride, and store your motorcycle. There are only two things you might need to know about your Z-Force BMS:

- Beep-Signals

The BMS will emit an “OK” beep-tone every time you turn-on your motorcycle. The BMS might also respond to other internal conditions and errors with different kinds of beeps. The following section explains the different beep patterns and their meanings.

•Safety Interlocks

The BMS can disable the motorcycle's throttle control if the power pack is fully discharged, or in case of other errors. The BMS can also disable charging under certain circumstances. The following information explains the different conditions which can cause the BMS to disable the throttle control or the power pack charger.

Beeps

The BMS includes an electronic beeper sealed inside the power pack. The beeper is located on the left front of the power pack behind the opening (A). Do not cover this opening, it is intentionally left open.

Technical line drawing of a rectangular electronic device with mounting holes and a labeled component (A), no text or symbols present.

The BMS will beep only under two circumstances:

- When the motorcycle is turned ON, the BMS will perform a self-test. It will always sound a beep-signal when the test finishes. The beep pattern reports the self-test result.

• Whenever the key switch is ON, and the power pack is nearly empty. The BMS will continuously sound a warning when the power pack is low. The warning will decrease in frequency and will still emit when the motorcycle is turned OFF.

Power Pack Charger

Keep your power pack connected to the charger when your motorcycle is sitting in storage or if it will be sitting unused for more than 7 days. The power pack must be charged within 24 hours if fully discharged, and charged within 60 days if stored fully charged. Zero recommends you plug in your Zero motorcycle after 7 days, even if fully charged. Please leave your Zero motorcycle plugged in whenever possible.

WARNING: Charge the Zero power pack with the Zero charger.

When charging the motorcycle's power pack the charger can be left on, even after the power pack is fully charged. There are two possible cases that can occur:

- When left on the charger, the power pack will receive a full charge. Once fully charged, the charger will check the status of the power pack once every 72 hours to ensure that it maintains a full charge. When fully charged, a green light will illuminate on the charger. Should the charger not read that the power pack is full, it will continue to attempt to fully charge the power pack. In this event the green light may not illuminate; however, the power pack may be fully charged. To ensure that the power pack is charged, check the charge indicator prior to riding.

• If the power pack terminates the charge before the charger reaches the state previously mentioned, then the charger will continue to cycle and will top off the power pack until the power pack is removed, or the charger reaches the complete state previously noted.

B. 80% Charge The 80% Charge LED is an amber indicator. If it is on solid, the bulk

charge phase is complete, 80% charged. Charger is now in absorption phase. If the indicator is flashing, there are two issues that can cause this:

•The charger and BMS are balancing

•The BMS is stopping the charge because one or more cells have reached maximum voltage.

C. 100% Charge

The 100% Charge LED is a green indicator. If it is on solid, the charging is complete and the charger will enter maintenance mode. If it is flashing, the absorption phase is complete and the charger is in finish phase.

D. AC ON

The AC ON LED is an amber indicator. If it is on solid, the AC power is good. If it is flashing, the AC voltage is low. Check for proper voltage, and if an extension cord is being used, verify that it is of the correct length. Maximum length is 7.6 m (25 ft.) 12-AWG.

E. Fault

The Fault LED is a red indicator indicating a charger error. If it is flashing, reset the charger and see section 6, Troubleshooting.

Charging The Power Pack

Note: Your power pack is equipped with an "Emergency Energy Reserve Beep." When your power pack makes an audible beep, it has only a few miles of range left. This beep tells you your power pack is dangerously low on energy and needs to be recharged immediately. Your power pack will continue to beep even when it's charging until it has recovered its "Emergency Energy Reserve."

Note: When the motorcycle's charge indicator is on the third bar (1/2) X/MX - Dirt or fifth bar (1/2) X/MX/XU - Street Legal when not under load, the power pack needs to be charged. Frequent top off charging is good for the power pack's life span, so do not hesitate to charge frequently.

WARNING: Charge the Zero power pack with the Zero charger. It is possible for lithium ion cells to overheat and fail.

It is recommended to charge in a location that is away from combustible materials and in a well-ventilated area. Avoid outdoor charging of your power pack in the rain.

The minimum charge temperature is 0^ C ( 32^ F).

The maximum power pack internal charging temperature is 65^ C ( 149^ F). If the power pack is kept in an environment over 65^ C ( 149^ F), it will not accept a charge until it is moved to a cooler location. Also if the pack has just been run hard, it may internally be above 65^ C ( 149^ F) even if the ambient temperature is lower. If you experience a pack that will not take a charge, ensure the internal temperature is below 65^ C ( 149^ F). If the power pack was recently run and it will not take a charge, the power pack should cool and begin taking a charge in around 30 minutes or less.

The max charging temperature cutoff is a power pack longevity feature. Charging at higher temperatures can shorten the life of the power pack.

Operating Your Motorcycle

Starting

1. Turn the key switch to the ON position.
2. Verify that the charge indicator reads fully charged.
3. With the brake applied, press the motor stop switch to the ON position.
4. Release the brake and twist the throttle towards you (counter-clockwise) to increase speed. When the throttle is twisted away from you (clockwise), the speed will decrease.

Braking

On the right side of the handlebar is a hand operated brake lever. This brake lever controls the front brake when the lever is squeezed. On the right lower side, next to the foot peg, is the foot operated brake lever. This lever controls the rear brake. When braking, the throttle should be in the closed position.

The front and rear brakes should be applied together, with a slight amount more braking on the front.

CAUTION: If you apply the front or rear brakes hard enough, it is possible to lock the wheels. This could cause you to lose control of the motorcycle. We suggest progressive use of the brakes to bring the Zero motorcycle to a complete stop without locking the wheels. Your Zero motorcycle is a light-weight performance product and therefore practice is recommended to safely perfect emergency stops.

Stopping

1. With the throttle in the closed position and the brake applied, press the motor stop switch to the OFF position. This switch can also be used in an emergency to shut the motor off.
2. Turn the key switch to the OFF position and remove the key. To prevent theft, the key should be removed anytime the motorcycle is left unattended.
3. Be sure to charge the power pack after each ride. See Charging The Power Pack on page 4-14.

Suspension Adjustment

Front Fork Adjustment

A shock has two main actions: compression when the shock gets compressed, and rebound when the shock returns back to full length. Compression damping is the adjustment that determines how fast or slow the fork compresses. Rebound damping is the adjustment that determines how fast or slow the fork rebounds.

1. Bleed Screw - The Allen screw (A) at the top of the fork leg is the "bleed" screw. The bleed screw serves two purposes:

- Transporting your motorcycle. See Transporting on page 1-13.

- Bleeding the fork: Bleed the fork regularly, let any excess air out after each ride.

1. Rebound Damping - The rebound damping is adjusted by turning the slotted brass adjuster screw (B) on the top of both fork legs. Next to it will be the writing S-F, meaning Slow and Fast.

The adjuster has 18 stages of adjustment. This determines how quickly the fork returns to its extended position after being compressed.

Turning the rebound adjuster screw clockwise will slow the rebound speed down making it better for larger, rolling terrain or bumps. Turning the rebound adjuster screw counter-clockwise will increase the rebound speed making it better for smaller, rougher bumps. Adjust each fork leg evenly.

1. Compression Damping - The compression damping is adjusted by turning a screw on the bottom of each fork leg. There is a rubber dust cover protecting the screw and a jam nut (C) securing the screw (D). The adjuster has 12 stages of adjustment. Turn the adjuster clockwise for slower compression. To speed up compression, turn the adjuster counter-clockwise. Start with a middle setting and fine tune the compression from there. Proper compression will allow the tire to track the ground over consecutive bumps. Compression that is set too slow will pack-up (feel harsh over consecutive bumps) while compression that is set too fast will cause the fork to bottom out harshly. If the fork is bottoming out, turn the adjuster one click at a time until the bottoming-out stops. Adjust each fork leg evenly. Replace the rubber dust cover after the adjustment.

Rear Shock Adjustment

Spring Adjustment:

Obtaining the correct rear spring rate is critical for proper handling. The spring rate must be set to match the weight of the rider. The spring is preloaded for an 82 kg (180 lb) rider. Heavier riders require stiffer spring rates. A good approximation of your rear spring requirements can be found by measuring the rear suspension's sag. This measurement will quickly determine if your rear spring is approximately correct for your weight. This adjustment is a recommended guideline; personal riding preference may vary from the specifications given.

- Checking Sag

1. Support your motorcycle on a stand with the rear wheel off the ground.
2. Measure vertically from the rear axle to the rear fender; mark this spot as it will be used for other measurements.
3. Record this measurement; this will be measurement M1.

1. Remove the motorcycle from the stand.
2. Wearing your normal riding apparel, sit on the motorcycle.
3. Have an assistant hold the motorcycle up, your feet should be on both pegs.

4. Bounce the suspension a couple of times.

5. Have a second assistant take a measurement using the same locations as in step 2.

6. Record this measurement; this will be measurement M2.

1. Subtract the second measurement (M2) from the first measurement (M1).

Example:

M1 600 mm		(24 in)
M2 - 500 mm		(28 in)
Sag = 100 mm		(4 in)

The total sag is 100 mm (4.0 in). Refer to the chart below for the correct sag. If the sag is not correct, the spring pre-load should be adjusted. See Spring Pre-load Adjustment.

MODEL SAG
X - Dirt/Street Legal 68 mm (2.68 in)
MX - Dirt/Street Legal 68 mm (2.68 in)
XU - Street Legal 46 mm (1.81 in)

•Spring Pre-load Adjustment

1. Clean any dirt or debris from the threads of the shock near the lock ring (A).
2. Using a lock ring wrench loosen the lock nut (A).
3. For measurements less than the specified value, decrease the pre-load on the spring by turning the spring nut (B) counter-clockwise on the shock. If more than specified value, increase the pre-load on the spring by turning the spring nut (B) clockwise on the shock.
4. Recheck the sag. If the sag is correct, tighten the lock nut (A).

- Rebound Adjustment - The rebound adjuster knob (C) is at the bottom of the shock. It has 8 stages of adjustment. Printed on the knob is S-F, meaning Slow and Fast. The rebound adjuster knob controls how slow or fast the shock returns to its extended position after being compressed. Turning the knob clockwise, or S direction, is good for big impacts. Turning the knob counterclockwise, or F direction, is good for many smaller and more frequent impacts.

(MX - Dirt and Street Legal)

•Compression Adjustment - The compression adjustment knob is under the rear of the seat. It has 21 stages of adjustment. The knob has HARD (slower compression) and SOFT (faster compression). Turn the adjuster clockwise for slower compression. To speed up compression, turn the adjuster counter-clockwise. Start with a middle setting and fine tune the compression from there. Proper compression will allow the tire to track the ground over consecutive bumps. Compression that is set too slow will pack-up (feel harsh over consecutive bumps) while compression that is set too fast will cause the shock to bottom out harshly. If the shock is bottoming out, turn the adjuster one click at a time until the bottom out stops.

(X - Dirt and X/XU - Street Legal)

•Compression Adjustment - The compression adjustment knob (D) is at the top of the shock. It has 18 stages of adjustment. The knob has + (slower compression) and - (faster compression). Turn the adjuster clockwise for slower compression. To speed up compression, turn the adjuster counter-clockwise. Start with a middle setting and fine tune the compression from there. Proper compression will allow the tire to track the ground over consecutive bumps. Compression that is set too slow will pack-up (feel harsh over consecutive bumps) while compression that is set too fast will cause the shock to bottom out harshly. If the shock is bottoming out, turn the adjuster one click at a time until the bottom out stops.

General Maintenance

Motor

CAUTION: Wear safety glasses when using compressed air to avoid eye injuries.

The motor requires little maintenance, but dust can collect inside the motor and can cause premature brush wear. If you ride in dusty conditions, it is important to blow the dust out of the motor with compressed air. Do this only in a well-ventilated area.

Brakes

Brake Fluid Level Inspection

WARNING: Do not spill brake fluid on painted surfaces; the finish could be damaged. Spilling brake fluid on the ABS body plastic will cause them to crack. Clean off any brake fluid spills immediately.

Always place a shop towel under the master cylinder reservoir prior to removing the cap/cover.

Low fluid levels may indicate worn brake pads or a leak in the hydraulic system. Inspect the brake pads for wear and/or the hydraulic system for leaks. Use only new DOT 4 brake fluid from a sealed container.

Front Brake

Inspect the level of the front brake fluid through the sight glass (B). If the fluid level is visibly below the low level indicator (C), brake fluid must be added. Clean any dirt or debris from the cover (A) before opening the reservoir.

1. Remove the two Phillips screws that secure the cover onto the reservoir.
2. Add new DOT 4 brake fluid.
3. Inspect the cover seal, ensuring that it is free of any wear or damage and that it is positioned correctly.
4. Install the cover and tighten the Phillips screws.

Rear Brake

Inspect the level of the rear brake fluid by inspecting the level through the reservoir housing. If the fluid level is visibly below the low minimum "MIN" indicator (B), brake fluid must be added. Clean any dirt or debris from the cap opening (A) before

opening the reservoir. Unscrew the cap and add new DOT 4 brake fluid. Inspect the cap seal ensuring that it is free of any wear or damage then reinstall the cap.

Brake Pad Inspection

The brake pads must be inspected when specified in the maintenance schedule. See Maintenance Schedule on pages 5-20 through 5-25. Visually inspect the brakes by looking at the remaining brake pad material through the sides of the brake caliper.

Replace the brake pads if either pad's thickness is 1.35 mm (0.05 in) or less. If the brake pads (A) are worn, replace both brake pads immediately.

Technical line drawing of a mechanical assembly with labeled component A (no text or symbols beyond label)

The brake rotor should be checked for thickness. The minimum thickness is 3.85 mm (0.15 in).

Suspension

Front

For maintenance, see Maintenance Schedule on pages 5-20 through 5-25.

To adjust the fork, see Suspension Adjustment on page 4-22.

Rear

CAUTION: The shock absorber assembly contains highly pressurized gas.

• Do not attempt to tamper with or open the cylinder or shock.
• Do not subject the shock to high temperature or open flame.

Doing either of these can cause the cylinder or shock to explode causing personal injury or death.

For maintenance, see Maintenance Schedule on pages 5-20 through 5-25.

To adjust the shock, see Suspension Adjustment on page 4-22.

Wheels And Tires

Inspect both wheels for the following:

•Bent, loose, or missing spokes
• Bent or cracked rims
- Impact marks on the rims

Inspect both tires for the following:

• Cuts, cracks, splits, or missing tread lugs in the tread or sidewall area
• Bumps or bulges within the tire body
- Uneven tire tread wear. Wear on one side of the tire tread or flat spots in the tire tread indicate a problem with the tire or motorcycle.
• Exposed tire tread or cords

If either of the wheels or tires are found to have any of these conditions, replace the wheel and/or tire immediately.

Tire Inflation

CAUTION: Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation, "blowout," or unexpected loss of motorcycle control causing personal injury and possible death.

The tire inflation pressure should be checked and adjusted before each ride. The tire pressure is checked using an accurate gauge when the tires are cold. This means that the tires have not been ridden on for 3 hours. Always replace the valve stem cap when finished.

Drive Chain

Cleaning The Drive Chain

CAUTION:

• Wear safety glasses when cleaning the chain to prevent eye injuries.
• Never have the motor spinning the wheel. Turn the wheel only by hand. Failure to do so could result in serious personal injury.
• Never place your hand or any other body part between the chain and sprockets. Work with the chain only in the middle between the two sprockets. Failure to do so could result in serious personal injury.
• Do not allow any of the cleaner to get on the brake rotors or brake pads. If the rotors are contaminated with cleaner, it will impair the motorcycle's ability to stop. This could result in serious personal injury.

Follow the manufacturer's instructions for the chain cleaner you are using; page 5-10 contains general guidelines. Do not allow any of the cleaner to get on the brake rotor.

1. Remove the key from the key switch.
2. Set the motorcycle on a stand or lift so the rear wheel is free to spin. While turning the wheel by HAND, spray the inside of your entire chain with a good coating of chain cleaner and let it sit for a few minutes.
3. Using a brush, fill the bristles with spray from the chain cleaner. Begin gently scrubbing the chain on the top of your swingarm using the brush.
4. Do this for the entire length of the chain. Now do the same thing for the inside/bottom of the chain.
5. Using the brush, clean both sides of the rear sprocket. Let this soak for 5 minutes.
6. Using a water hose, rinse the entire chain and using a clean rag wipe any residual moisture from the chain.

Lubricating The Drive Chain

CAUTION:

- Wear safety glasses when lubricating the chain to prevent eye injuries.

• Never have the motor spinning the wheel. Turn the wheel only by hand. Failure to do so could result in serious personal injury.
• Never place your hand between the chain and sprockets. Work with the chain only in the middle between the two sprockets. Failure to do so could result in serious personal injury.
• Do not allow any of the lubricant to get on the brake rotors or brake pads. If the rotors are contaminated with lubricant, it will impair the motorcycle's ability to stop. This could result in serious personal injury.

Follow the manufacturer's instructions for the chain lubricant you are using; below are the general guidelines.

1. Turn the wheel backwards slowly and spray the inside of the chain on the inside of the links.
2. Turn the wheel backwards slowly and spray the outside of the chain on the outside of the links.
3. Let the motorcycle stand for 30 minutes to allow the lubricant to penetrate the link rollers.

Checking The Drive Chain

1. Remove the key from the key switch.
2. Using a ruler, grasp the chain halfway between the front and rear sprockets.
3. The chain should move 16 mm (.63 in) in either direction, so 32 mm (1.25 in) of total free play.
4. If the chain's free play is not within specifications it will need to be adjusted. See the Drive Chain Adjustment Procedure.

Drive Chain Adjustment Procedure

1. Remove the key from the key switch.
2. Loosen both front motor mount 5/16" hex bolts (D). See image on next page.
3. Loosen both rear motor mount 7/32" hex bolts (A).
4. Loosen the 10 mm jam nut (B) on the chain tensioner.

Note: Chain tension will increase slightly when motor mount bolts are fully torqued.

1. Turn the tensioner bolt (C) a 1/4 turn at a time until the chain free play is within specification.
2. Tighten all motor mount Allen bolts. See Bolt Torque Table on page 5-2.
3. Tighten the 10 mm jam nut on the chain tensioner.
4. Test ride the motorcycle.
5. Recheck the chain for proper adjustment after the test ride and readjust if necessary.

Headlight Alignment

The headlight should periodically be checked for correct alignment. It must be aligned any time the suspension sag is adjusted because this will affect the headlight alignment. Before the headlight can be aligned, the suspension and tire pressure must be correctly adjusted. The headlight can be adjusted horizontally and vertically. If the horizontal adjustment is off, the beam will point too far off to one side. If the vertical adjustment is off, it will cause the beam to point too closely to or too far ahead of the motorcycle. With the headlight on the low beam position, the motorcycle perpendicular to the ground, and the operator sitting on the motorcycle, verify the beam alignment. The headlight is adjusted at the factory with a 0.5-2.5% dip.

To adjust the headlight, remove the adjustment nut cover. Loosen the nut (A) and move the headlight until the correct beam alignment is achieved. Tighten the bolt. See Bolt Torque Table on page 5-2. Install the adjustment nut cover.

Cleaning

To prolong the life of your motorcycle, it should be washed periodically. Regular cleaning, using correct methods, is an important factor in maintaining the value of your Zero motorcycle. It also ensures that safety-relevant parts remain in full working order.

CAUTION: After cleaning and before starting on your journey, always test the brakes.

If tar, bugs, or other similar deposits have accumulated, wash them off as soon as possible. Do not use steam cleaners; they can cause water intrusion of bearing, seals and electrical components. When using pressure washers, avoid spraying water of great force around the instrument panel, power pack or controller. Avoid using strong acidic wheel cleaners, especially on spoked wheels. If such products are used on hard to remove dirt, do not leave the cleaner on the affected area any longer than instructed. Thoroughly rinse the area off with water, immediately dry it, and then apply a corrosion protection spray.

WARNING: Improper cleaning can damage electrical components, cowlings, panels and other plastic parts. Use only a soft, clean cloth or sponge with mild detergent and water to clean plastic.

Do not use any harsh chemical products on plastic parts. Be sure to avoid using cloths or sponges which have been in contact with strong abrasive cleaning products, solvents or thinner, fuel (gasoline), rust removers or inhibitors, brake fluid, antifreeze or electrolyte.

After gently washing the motorcycle be sure to allow all of the electrical components to dry prior to operation. If the motorcycle is ridden immediately after being washed, apply both brakes several times in order to remove any moisture from the brake linings. Do not use products such as tire dressings on tires as this will deteriorate traction.

Parking And Long Term Storage

1. It is required to always leave the power pack plugged in when the Zero is not in use. The Zero charger is designed to maintain a balanced and complete charge at all times without wasting any electricity.
2. Over extended periods of time, the power pack is checked every 72 hours to ensure that the cells are balanced and that the power pack is full. Once the power pack has reached a complete charge it is checked every 72 hours, remove over extended periods of time.
3. To prolong the life of your power pack you should store your motorcycle in a cool area. Storing your motorcycle in a hot area will cause your power pack's life to be shortened.
4. If, for some reason, your motorcycle was not plugged in for several days you should always charge it up before operation.

For more information on the power pack and the electrical system see Battery Management System (BMS) on page 4-9.

WARNING: Opening of the power pack is for trained Zero Motorcycles' technicians. Please be aware that incorrect handling of a Zero power pack can be dangerous. DO NOT OPEN!

Understanding Beep Sequences

The Battery Management System (BMS) is located inside the power pack and is fitted with a beeper to provide audible notifications about the status of the power pack. Below you will find information on the meaning of the beep sequences.

PATTERN WHEN MEANING SOLUTION
1 Short Key	Self-Test Pass BMS OK. Ready to ride!
1 Trill2 Long		Key-on	Charger Still Plugged In	Unplug charger & try again.
2 Long Key				Charge power pack before riding.
4 Long Key
5 Long Key			Power Pack Unbalanced	Leave on charger for 24 hours.
4 Short1 Long		Riding	Low-Power Pack Warning	Charge soon.

Power Pack Empty

If the power pack is completely empty, an error-beep will sound and the BMS will disable the throttle. You cannot ride the motorcycle until you recharge the power pack. If the Power Pack Empty error-beep still sounds after two hours of charging time, contact your CSC. Your power pack may need to be repaired or replaced.

Too Hot

The power pack contains internal temperature sensors. If the BMS measures excessive internal temperatures, it will sound an error-beep and disable the throttle. You cannot ride the motorcycle until the power pack cools down. Place the motorcycle in a cool, well-ventilated location and wait a few minutes before riding again. If the Too Hot error-beep still sounds after the power pack has had time to cool down, contact your CSC. Your power pack may need to be repaired or replaced.

Power Pack Unbalanced

The power pack contains many individual cells. The BMS continuously monitors the cells and tries to keep them all “in balance” (at the same level-of-charge). If any of the cells are grossly out-of-balance, the BMS will sound a Power Pack Unbalanced error-beep and disable the throttle. You cannot ride the motorcycle until the problem is resolved.

The solution to the problem is to plug in the charger and allow the power pack to charge for 72 hours. This will allow the BMS to re-balance the cells in the power pack. If the Power Pack Unbalanced error-beep still sounds after the power pack has spent more than 72 hours charging, contact your CSC. Your power pack may need to be repaired or replaced.

Low Power Pack Warning

The BMS provides a Low Power Pack warning telling the operator that the remaining range is limited, and the power pack should be recharged soon. This is equivalent to a "low fuel" warning-light on a gasoline-powered vehicle. This beep warning is different from the others because it can sound at any time when the motorcycle is on (the other warnings only sound when the key switch is first turned ON).

The Low Power Pack warning beep will sound continuously until either (1) the motorcycle is turned off, or (2) the throttle control is disabled for any reason, which includes the power pack being completely empty. The Low Power Pack warning beep will sound when you can still ride the motorcycle, but the remaining range is limited. It means: "Stop at a destination and charge-up."

The solution is to recharge the power pack. If the Low Power Pack warning beep still sounds after the power pack has charged for two hours, contact CSC. Your power pack may need to be repaired or replaced.

Other Error-Beep Patterns

If the BMS in your power pack produces an error-beep which is not described in the Beep Patterns Table, then the power pack has encountered a serious internal hardware problem and must be repaired or replaced by a CSC.

BMS Appendix

There are other beeps that may occur under two circumstances that operators will normally never see. Unlike many electronic systems, the BMS essentially never “power cycles.” A typical BMS is powered-on only once, in the factory, when it is connected to the wiring harness inside the power pack. It may quite possibly operate continuously for years without ever being powered down.

But on that one occasion when it is first powered on, the BMS will perform a simple power ON self-test and report the result with a beep pattern. Note that this power ON self-test (and the resulting beep patterns) is different from the key on self-test. The self-test (and the beeps) happens immediately when the board is first powered up (connected to a power pack).

During service or maintenance, the BMS board may be disconnected from, and then reconnected to, the power pack wiring harness. In those cases, the BMS will perform the power ON self-test (and result-beeps) every time it is plugged in.

It is possible to encounter the power ON self-test result error beeps from a badly malfunctioning or damaged power pack. If so, you should contact your CSC. Your power pack may need to be repaired or replaced.

Beep Patterns

PATTERN WHEN MEANING
2 Short		Pwr-on M-cmd	Pass Power ON self-test/ Mfg.test
3 Long		Pwr-on M-cmd	Fail Power ON self-test/ Mfg.test

Safety Interlocks

If the BMS detects a serious internal fault, it can take either or both of two actions to prevent damage to the power pack:

1. Throttle Disable The BMS will disable the throttle if the power pack is empty, or if the BMS detects certain serious internal problems. You cannot ride the motorcycle until the problem is resolved.
2. Charger Disable The BMS will prevent charging if it detects certain serious internal problems, even if the power pack is connected to a charger and plugged in to AC power. The power pack cannot be charged until the problem is resolved.

The Throttle Disable Interlock

The BMS communicates with the main motorcycle control module. The BMS can send a signal to the main motorcycle controller requesting that the throttle control on the motorcycle be disabled. When the throttle control is disabled, the motor will not deliver power to the rear wheel, and the motorcycle cannot be ridden.

If the throttle is disabled while riding, the motorcycle will cease to provide power, and the operator must pull over to a safe location.

All conditions which would cause the BMS to disable the throttle are also signaled by an error beep pattern at self-test. If you suspect that the BMS has disabled the throttle control on your motorcycle, turn the key switch OFF and back ON again to enter self-test mode. The beep pattern from the BMS will report any of the error conditions which would cause the BMS to disable the throttle.

Each of these conditions, the associated self-test beep pattern, and the suggested remedies, are discussed in Understanding Beep Sequences on page 6-3.

•Power Pack Empty
• Too Hot
•Power Pack Unbalanced

The Charger Disable Interlock

When the charger is attached and plugged in to AC power, the BMS communicates with the charger. The BMS can send a signal to the charger requesting that charging terminate immediately. When the charger is disabled, the indicator lights on the charger will show that charging has stopped.

There are two conditions that will cause the BMS to disable charging. One of these conditions is also reported by a self-test result beep pattern; the other is not.

Too Hot

If the BMS detects high internal power pack temperatures, it will both disable the throttle and prevent charging. This condition is also reported by an error beep pattern after BMS self-test when the motorcycle is turned ON. See Understanding Beep Sequences on page 6-3 for a description of the Too Hot error beep and the solutions.

Power Pack Full (High Pack Voltage)

If the BMS detects that the power pack is already full, it will disable further charging to prevent damage to the power pack.

This is not an error-condition; it is the result of a successful charging cycle. There is no self-test error beep which reports this condition.

During an ordinary charging cycle, when the cells are balanced, the charger (not the BMS) will sense that the power pack is full and terminate the charging cycle with a “green light.” The BMS does have a redundant back-up mechanism to prevent overcharging of the power pack. If the charger fails to terminate a charging cycle when the power pack is full, the BMS will terminate charging itself to prevent damage.

Instrument Panel

Motor Temperature Indicator

PATTERN MEANING
Slow Constant Blink Motor	Temperature Warning Stage 1
Fast Constant Blink Motor	Temperature Warning Stage 2
Intermittent Fast Blink Motor	Temperature Warning Stage 3
Indicator Always ON Motor	Temperature Disabled
2 Fast-Pause-2 Fast High Power Pack Temperature

The Zero is equipped with a motor temperature sensor that senses the temperature of the motor and power pack. This indicator will blink in the unlikely event that you exceed the motorcycle's performance capabilities; it will provide you with an instrument panel illumination warning indicator (A).

X/MX - Dirt

X/MX/XU

Stage 1

The motor begins to reach an undesirable temperature:

• A slow blink is clearly seen on the warning indicator.

• You can continue to ride without performance interruptions.
  •You should reduce speed - this will lower power output and the motor temperature to eliminate the blinking warning indicator.

Stage 2

If the motor continues to heat up:

• A fast blink is clearly seen on the warning indicator.
  •The power to the motor begins to drop off, resulting in a noticeable reduction in available torque. This provides tactile feedback to the rider and also helps prevent the motor from heating further. As the motor cools again, full-power will be restored.
  •At this point it is strongly recommended that you reduce your speed and consider finding a safe area to stop.
• You may still have time to back off the throttle to reduce heat. This will restore full power to the motor and eliminate the warning indicator.

Stage 3

If the critical temperature threshold of the motor is reached:

You will not reach this stage without knowingly ignoring stage 1 and stage 2.

• A ten second sequence of close intervals of rapid pulsing will be visible on the warning indicator and then power to the motor will be disabled.
- You must quickly find a safe place to park the motorcycle.
- When power to the motor is disabled the warning indicator goes solid.
•The motor should take no longer than about 10 minutes to cool.
- When the warning indicator turns off you can safely operate the motorcycle again.
- Use the throttle sparingly at first to ensure that the motor does not overheat.

Motor Temperature Disabled

This warning indicator is on solid. This is an indication that the motor temperature sensor is not detected. Check the connections to the temperature sensor. The connection is located in the motor cooling shroud near the top. If a problem is not found, contact your CSC.

High Power Pack Temperature

If you see two fast blinks followed by two fast blinks this indicates you need to let the power pack cool in a well-ventilated location. If the high power pack temperature still exists after the power pack has had time to cool off, contact your CSC.

The next stage is the temperature warning indicator is blinking rapidly, please pull over and allow the power pack to cool off.
