MOTORCYCLES ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND OPERATION ARE

DEPENDENT UPON THE USE OF PROPER RIDING TECHNIQUES AS WELL AS THE EXPER-

TISE OF THE OPERATOR. EVERY OPERATOR SHOULD KNOW THE FOLLOWING REQUIRE-

MENTS BEFORE RIDING THIS MOTORCYCLE.

HE OR SHE SHOULD:

1. OBTAIN THOROUGH INSTRUCTIONS FROM A COMPETENT SOURCE ON ALL ASPECTS

OF MOTORCYCLE OPERATION.

2. OBSERVE THE WARNINGS AND MAINTENANCE REQUIREMENTS IN THE OWNER’S MAN-

UAL.

3. OBTAIN QUALIFIED TRAINING IN SAFE AND PROPER RIDING TECHNIQUES.

4. OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED BY THE OWNER’S MANUAL

AND/OR WHEN MADE NECESSARY BY MECHANICAL CONDITIONS.

Safe riding

1. Always make pre-operation checks. Careful checks may help prevent an accident.

2. This motorcycle is designed to carry the operator and a passenger.

3. The failure of motorists to detect and recognize motorcycles in traffic is the predominating cause

of automobile/motorcycle accidents. Many accidents have been caused by an automobile driver

who did not see the motorcycle. Making yourself conspicuous appears to be very effective in

reducing the chance of this type of accident.

Therefore:

a. Wear a brightly colored jacket.

b. Use extra caution when approaching and passing through intersections, since intersections

are the most likely places for motorcycle accidents to occur.

c. Ride where other motorists can see you. Avoid riding in another motorist’s blind spot.

QSAFETY INFORMATION

4. Many accidents involve inexperienced operators. In fact, many operators who have been

involved in accidents do not even have a current motorcycle license.

a. Make sure that you are qualified and that you only lend your motorcycle to other qualified oper-

ators.

b. Know your skills and limits. Staying within your limits may help you to avoid an accident.

c. We recommend that you practice riding your motorcycle where there is no traffic until you have

become thoroughly familiar with the motorcycle and all of its controls.

5. Many accidents have been caused by error of the motorcycle operator. A typical error made by

the operator is veering wide on a turn due to EXCESSIVE SPEED or undercornering (insufficient

lean angle for the speed).

a. Always obey the speed limit and never travel faster than warranted by road and traffic condi-

tions.

b. Always signal before turning or changing lanes. Make sure that other motorists can see you.

6. The posture of the operator and passenger is important for proper control.

a. The operator should keep both hands on the handlebar and both feet on the operator footrests

during operation to maintain control of the motorcycle.

b. The passenger should always hold onto the operator, the seat strap or grab bar, if equipped,

with both hands and keep both feet on the passenger footrests.

c. Never carry a passenger unless he or she can firmly place both feet on the passenger

footrests.

7. Never ride under the influence of alcohol or other drugs.
