7 PREPARING FOR USE 56

7.1 Advice on first use

Danger

Danger of accidents Danger arising from the rider's judgement being impaired.

– Do not operate the vehicle while under the influence of alcohol, drugs and certain medications or physically or mentally

impaired.

Warning

Risk of injury Missing or poor protective clothing presents an increased safety risk.

– Wear protective clothing (helmet, boots, gloves, pants and jacket with protectors) every time you ride the vehicle. Always wear

protective clothing that is in good condition and meets the legal requirements.

Warning

Danger of crashing Poor vehicle handling due to different tire tread patterns on front and rear wheels.

– The front and rear wheels must be fitted with tires with similar tread patterns to prevent loss of control over the vehicle.

Warning

Danger of accidents Non-approved or non-recommended tires and wheels impact the handling characteristic.

– Only use tires/wheels approved by KTM with the corresponding speed index.

Warning

Danger of accidents Reduced road grip with new tires.

– New tires have a smooth rolling surface and therefore cannot provide full road grip. The entire rolling surface must be rough-

ened in the first 200 kilometers (124.3 miles) by moderate riding at alternating angles. The full grip levels are not achieved

until the tires have been run in.

Info

When using your vehicle, remember that others may feel disturbed by excessive noise.
