BE EXTRA SAFETY CONSCIOUS ON BAD WEATHER DAYS

HYOSUNG MS3-250 - BE EXTRA SAFETY CONSCIOUS ON BAD WEATHER DAYS - 1

WARNING

Riding on bad weather days, especially wet ones, requires extra caution.

Braking distances double on a rainy day. Stay off of the painted surface marks, manhole covers and greasy appearing areas as they can be especially slippery.

Use extreme caution at railway crossings and on metal gratings and bridges. Whenever you have a doubt about road condition, slow down!

HYOSUNG MS3-250 - WARNING - 1

WARNING

The most common type of motorcycle accident occurs when a car traveling towards a motorcycle turns round corner in front of the motorcyclist. Ride defensively.

Wise motorcyclist uses a strategy of assuming they are invisible to other drivers, even in broad daylight. Wear bright, reflecting clothing. Do not ride in another driver's blind spot.

ACCESSORY INSTALLATION AND PRECAUTION SAFETY TIPS

There are a great variety of accessories available to Hyosung owners. Hyosung can not have direct control over the quality or suitability of accessories you may wish to purchase except genuine parts.

The addition of unsuitable accessories can lead to unsafe operating conditions. It is not possible for Hyosung to test each accessory on the market or combinations of all the available accessories, however, your dealer can assist you in selecting quality accessories and installing them correctly.

Use extreme caution when selecting and installing the accessories for your Hyosung. We have developed some general guidelines which will aid you when deciding whether, and how to equip your motorcycle.

HYOSUNG MS3-250 - ACCESSORY INSTALLATION AND PRECAUTION SAFETY TIPS - 1

WARNING

Improper accessories or modifications can make your motorcycle unsafe and can lead to an accident.

Never modify the motorcycle with improper or poorly installed accessories. Follow all instructions in this owner's manual regarding accessories and modifications. Use genuine Hyosung accessories or equivalent designed and tested for your motorcycle. Consult your Hyosung dealer if you have any questions.

  1. Anytime that additional weight or aerodynamic affecting accessories are installed, they should be mounted as low as possible, as close to the motorcycle and as near the center of gravity as is feasible. The mounting brackets and other attachment hardware should be carefully checked to ensure that it provides for a rigid, nonmovable mount. Weak mounts can allow the shifting of the weight and create a dangerous, unstable condition.

  2. Inspect for proper ground clearance and bank angle. An improperly mounted load could critically reduce these two safety factors. Also determine that the "load" does not interfere with the operation of the suspension, steering or other control operations.

  3. Accessories fitted to the handlebars or the front fork area can create serious stability problems. This extra weight will cause the motorcycle to be less responsive to your steering control. The weight may also cause oscillations in the front end and lead to instability problems. Accessories added to the machine should be as light as possible and kept to a minimum.

  4. The motorcycle may be affected by a lifting condition or by an instability in cross winds or when being passed or passing large vehicles. Improperly mounted or poorly designed accessories can result in an unsafe riding condition, therefore caution should be used when selecting and installing all accessories.

  5. Certain accessories displace the rider from his or her normal riding position.

This limits the freedom of movement of the rider and may limit his or her control ability.

  1. Additional electrical accessories may damage the existing electrical system. Severe overloads may damage the wiring harness or create a dangerous situation due to the loss of electrical power during the operation of the motorcycle.

When carrying a load on the motorcycle, mount it as low as possible and as close as possible to the machine. An improperly mounted load can create a high center of gravity which is very dangerous and makes the motorcycle difficult to handle. The size of the “load” can also affect the aerodynamics and handling of the motorcycle.

Balance the load between the left and right side of the motorcycle and fasten it securely.

MODIFICATION

Modification of the motorcycle, or removal of original equipment may render the motorcycle unsafe or illegal.

Obey all applicable equipment regulations in your area.

WARNING

Using either front or rear brake is dangerous and can cause skidding and loss of control.

HYOSUNG MS3-250 - WARNING - 1

WARNING

When approaching a turn, slow down or brake and take the turn at moderate, constant speed or accelerate slightly: braking in a turn will greatly increase your chances of skidding. Continued application of the brakes on long downhill grades may cause the brakes to overheat, thereby reducing brake efficiency. Never ride downhill with engine off!

HYOSUNG MS3-250 - WARNING - 1

WARNING

When you need to brake, close the throttle and use both brakes for smooth braking : take care to apply the right amount of pressure to both brakes.

Using one brake only gives less braking power and you could lock a wheel and lose grip.

To stop uphill, decelerate completely and use the brakes to keep the motor-cycle at standstill.

- The quick brake can cause skidding.

BREAK-IN

The opening explains how important proper break-in is to achieve maximum life and performance from your new Hyosung. The following guidelines explain proper break-in procedures.

★ MAXIMUM THROTTLE OPENING RECOMMENDATIONS

The table below shows the maximum throttle opening recommendation during the break-in period.

Initial 800km (500miles)Less than 1/2 throttle
Up to 1,600km (1,000miles)Less than 3/4 throttle

★ AVOID CONSTANT LOW SPEED

Operating the engine at constant low speed(light load) can cause parts to glaze and not seat in. Allow the engine to accelerate freely through the gears, without exceeding the recommended maximum limits. Do not, however, use full throttle for the first 1,600km (1,000 miles).

★ VARY THE ENGINE SPEED

The engine speed should be varied and not held at a constant speed.

This allows the parts to be “loaded” with pressure and then unloaded, allowing the parts to cool.

This aids the mating process of the parts.

It is essential that some stress be placed on the engine components during break-in to ensure this mating process.

Do not, though, apply excessive load on the engine.

★ BREAKING IN THE NEW TIRES

New tires need proper break-in to assure maximum performance, just as the engine does.

Wear in the tread surface by gradually increasing your cornering lean angles over the first 160km (100miles) before attempting maximum performance. Avoid hard acceleration, hard cornering, and hard braking for the first 160km (100miles).

HYOSUNG MS3-250 - ★ BREAKING IN THE NEW TIRES - 1

WARNING

Failure to perform break-in of the tires could cause tire slip and loss of control. Use extra care when riding on new tire. Perform proper break-in of the tire as described in this section and avoid hard acceleration, hard cornering, and hard braking for the first 160km (100miles).

★ ALLOW THE ENGINE OIL TO CIRCULATE BEFORE RIDING

Allow sufficient idling time after warm or cold engine start up before applying load or revving the engine. This allows time for the lubricating oil to reach all critical engine components.

★ OBSERVE YOUR FIRST, AND MOST 1,000km SERVICE

The 1,000km (600miles) service is the most important service your motorcycle will receive.

During break-in procedures, all of the engine components will have worn in and all of the other parts will have seated in.

All adjustments will be restored, all fasteners will be tightened, and the dirty engine oil will be replaced.

Timely performance of the 1,000km (600miles) service will ensure optimum service life and performance from the engine.

CAUTION

Service should may be performed before 1,000km (600miles) on motorcycle that are used under severe conditions.

CAUTION

The 1,000km (600miles) service should be performed as outlined in the PERIODIC MAINTENANCE section of this Owner's Manual.
