Frequently Asked Questions - FR 450 Rally (2020) HUSQVARNA

What type of fuel should I use for the FR 450 Rally?
Use unleaded super fuel with a minimum octane rating of ROZ 95 / RON 95 / PON 91 that meets DIN EN 228. Fuel with up to 10% ethanol (E10) is safe. Do not use methanol or high-ethanol blends.
How do I check the engine oil level?
Check the engine oil level with the motorcycle upright and on a level surface. The engine should be warm but not running. Remove the dipstick, wipe it clean, reinsert without screwing, and check that the oil level is between the minimum and maximum marks. Refer to section 18.1 of the manual.
What is the recommended break-in procedure?
During the first operating hour, do not exceed 7,000 rpm. For the first 3 operating hours, keep engine performance at or below 75%. Avoid fully opening the throttle and vary engine speed. After break-in, ride normally.
How do I adjust the chain tension?
Place the motorcycle on a stand so the rear wheel is off the ground. Loosen the rear axle nut and adjust the chain tensioners on both sides evenly. The chain should have about 40 mm (1.57 in) of vertical play at the middle of the lower chain run. Tighten the axle nut to the specified torque. See section 12.34.
How do I set the clock on the combination instrument?
With the motorcycle stationary, press the button until CLK appears at the bottom right. Press and hold the button for 2-3 seconds until the hour flashes. Use the + and - buttons to adjust, then wait 3-5 seconds to set minutes and seconds. The settings save automatically.
What type of brake fluid is recommended?
Use only brake fluid complying with DOT 4 or DOT 5.1 standards. Recommended brands include Castrol REACT PERFORMANCE DOT 4 and MOTOREX Brake Fluid DOT 5.1. Do not mix different types.
How do I clean the air filter?
Remove the air filter (see section 12.20). Clean it with a suitable air filter cleaner like MOTOREX Racing Bio Dirt Remover. Rinse with warm water, let dry, then oil the filter with foam filter oil (e.g., MOTOREX Racing Bio Liquid Power). Reinstall the filter properly.
What are the valve clearance check intervals?
The valve clearance should be checked at the one-time interval (after the first operating hour) and then periodically as per the service schedule. This requires specialist tools and should be done by an authorized Husqvarna workshop.
How do I start the engine in cold weather?
Push the cold start button all the way in (located at the bottom of the throttle valve body). Then press the start button for a maximum of 5 seconds. If the engine doesn't start, wait 5 seconds before trying again. At temperatures below 15°C, several attempts may be needed.
What does the malfunction indicator lamp mean?
When the yellow malfunction indicator lamp lights up or flashes, the OBD system has detected an error in the vehicle electronics. Stop safely and contact an authorized Husqvarna Motorcycles workshop as soon as possible to have the fault memory read.

During assembly, use new parts to replace parts which cannot be reused (e.g. self-locking screws and nuts, seals, sealing rings, O-rings, pins, and lock washers).

In the case of certain screws, a screw adhesive (e.g. L'ocite required. Observe the manufacturer's instructions.

If thread locker (e.g., Precote) has already been applied to a new part, do not apply any additional thread locker.

After disassembly, clean the parts that are to be reused and check them for damage and wear. Change damaged or worn parts.

After completing a repair or service work, check the operating safety of the vehicle.

2.8 Environment

If you use your motorcycle responsibly, you can ensure that problems and conflicts do not occur. To protect the future of the motorcycle sport, make sure that you use your motorcycle legally, display environmental consciousness, and respect the rights of others.

When disposing of used oil, other operating and auxiliary fluids, and used components, comply with the laws and regulations of the respective country.

Because motorcycles are not subject to the EU regulations governing the disposal of used vehicles, there are no legal regulations that pertain to the disposal of an end-of-life motorcycle. Your authorized Husqvarna Motorcycles dealer will be glad to advise you.

2.9 Owner's Manual

It is important that you read this Owner's Manual carefully and completely before making your first trip. The Owner's Manual contains useful information and many tips on how to operate, handle, and service your motorcycle. Only then will you find out how to customize the vehicle ideally for your own use and how you can protect yourself from injury.

Keep the Owner's Manual in an accessible place to enable you to refer to it as needed.

If you would like to know more about the vehicle or have questions on the material you read, please contact an authorized Husqvarna dealer.

The Owner's Manual is an important component of the vehicle and must be handed over to the new owner if the vehicle is sold.

2 SAFETY ADVICE

The Owner's Manual is also available for download from your authorized Husqvarna Motorcycles dealer and on the Husqvarna Motorcycles website.

International Husqvarna Motorcycles website: www.husqvarna-motorcycles.com

3.1 Manufacturer and implied warranty

The work prescribed in the service schedule must only be carried out in an authorized Husqvarna Motorcycles workshop and confirmed in the Husqvarna Motorcycles Dealer.net, as otherwise all warranty claims will be void. Damage or secondary damage caused by tampering with and/or conversions on the vehicle are not covered by the manufacturer warranty.

3.2 Fuel, auxiliary substances

HUSQVARNA FR 450 Rally (2020) - Fuel, auxiliary substances - 1

Note

Environmental hazard Improper handling of fuel is a danger to the environment.

- Do not allow fuel to enter the groundwater, the soil, or the sewage system.

Use fuels and auxiliary substances in accordance with the Owner's Manual and specification.

3.3 Spare parts, accessories

For your own safety, only use spare parts and accessory products that are approved and/or recommended by Husqvarna Motorcycles and have them installed by an authorized Husqvarna Motorcycles workshop. Husqvarna Motorcycles accepts no liability for other products and any resulting damage or loss. Certain spare parts and accessory products are specified in parentheses in the descriptions. Your authorized Husqvarna Motorcycles dealer will be glad to advise you.

The current Husqvarna Motorcycles accessories for your vehicle can be found on the Husqvarna Motorcycles website.

International Husqvarna Motorcycles website: www.husqvarna-motorcycles.com

3.4 Service

A prerequisite for perfect operation and prevention of premature wear is that the service, care, and tuning work on the engine and chassis is properly carried out as described in the Owner's Manual. An incorrect suspension setting can lead to damage and breakage of chassis components.

Use of the vehicle under difficult conditions, such as on sand or on wet and muddy surfaces, can result in significantly increased wear of components, such as the drive train, brake system, or suspension components. For this reason, it may be necessary to inspect or replace parts before the next scheduled service.

HUSQVARNA FR 450 Rally (2020) - Warning - 1

Info

If unusual noises occur while riding, stop immediately, switch off the engine, and contact an authorized Husqvarna Motorcycles workshop.

First gear is used for starting off and for steep inclines.

  • Shift into a higher gear when conditions allow (incline, road situation, etc.). To do so, release the throttle while simultaneously pulling the clutch lever, shift into the next gear, release the clutch lever and open the throttle.
  • After reaching maximum speed by fully opening the throttle grip, turn the throttle back so it is 34 open. This will barely reduce the speed, but fuel consumption will be considerably lower.

9 RIDING INSTRUCTIONS

  • Always open the throttle only as much as the engine can handle – abrupt throttle opening increases fuel consumption.
  • To shift down, apply the brakes and close the throttle at the same time.
  • Pull the clutch lever and shift into a lower gear, release the clutch lever slowly, and either open the throttle or shift again.
  • Switch off the engine if running at idle speed or stationary for a long time.
    Guideline
    ≥ 2 min
  • Avoid frequent and longer slipping of the clutch. This heats the engine oil, the engine, and the cooling system.
  • Ride at a low engine speed instead of at a high engine speed with a slipping clutch.

11.1 Checking basic chassis setting with rider's weight

HUSQVARNA FR 450 Rally (2020) - Checking basic chassis setting with rider's weight - 1

Info

When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

HUSQVARNA FR 450 Rally (2020) - Info - 1

natural_image Two line drawings of a person riding a motorcycle, no text or symbols present

- For optimal motorcycle riding characteristics and to avoid damage to forks, shock absorbers, swingarm and frame, the basic settings of the suspension components must match the rider's weight. - On delivery, Husqvarna offroad motorcycles are adjusted for an average rider's weight (with full protective clothing).

Guideline

Standard rider weight 75 ... 85 kg (165 ... 187 lb.)

  • If the rider's weight is above or below this range, the basic setting of the suspension components must be adjusted accordingly.
  • Small weight differences can be compensated by adjusting the spring preload, but in the case of large weight differences, the springs must be replaced.

HUSQVARNA FR 450 Rally (2020) - Guideline - 1

11.2 Compression damping of the shock absorber

The compression damping of the shock absorber is divided into two ranges: high-speed and low-speed. High-speed and low-speed refer to the compression speed of the rear wheel suspension and not to the vehicle speed.

The high-speed compression adjuster has an effect, for example, when landing after a jump: the rear wheel suspension compresses quickly.

The low-speed compression adjuster has an effect, for example, when riding over long ground swells: the rear wheel suspension compresses slowly.

These two ranges can be adjusted separately, although the transition between high-speed and low-speed is gradual. Thus, modifications in the high-speed range affect the compression damping in the low-speed range and vice versa.

11.3 Adjusting the low-speed compression damping of the shock absorber

HUSQVARNA FR 450 Rally (2020) - Adjusting the low-speed compression damping of the shock absorber - 1

Coolant

Guideline

  • Only use high-grade, silicate-free coolant with corrosion inhibitor additive for aluminum motors. Low grade and unsuitable antifreeze causes corrosion, deposits and frothing.
  • Do not use pure water as only coolant is able to meet the requirements needed in terms of corrosion protection and lubrication properties.
  • Only use coolant that complies with the requirements stated (see specifications on the container) and that has the relevant properties.

Antifreeze protection to at least -25 °C (-13 °F)

The mixture ratio must be adjusted to the necessary antifreeze protection. Use distilled water if the coolant needs to be diluted.

The use of premixed coolant is recommended.

Observe the coolant manufacturer specifications for antifreeze protection, dilution and miscibility (compatibility) with other coolants.

JASO T903 MA2

Different technical development directions required a separate specification for motorcycles – the JASO T903 MA2 standard.

Earlier, engine oils from the automobile industry were used for motorcycles because there was no separate motorcycle specification.

Whereas long service intervals are demanded for automobile engines, the focus for motorcycle engines is on high performance at high engine speeds.

In most motorcycle engines, the transmission and clutch are lubricated with the same oil. The JASO T903 MA2 standard meets these special requirements.

SAE

The SAE viscosity classes were defined by the Society of Automotive Engineers and are used for classifying oils according to their viscosity. The viscosity describes only one property of oil and says nothing about quality.
