MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Checking the damping rubbers in the rear wheel *
In the Duke, the transmission of power to the rear wheel is damped. For this
purpose, the engine power is conveyed from the rear sprocket via 6 damping
rubbers
[1]
to the rear wheel. These 6 damping rubbers wear with increasing
operation time, and should be checked for wear whenever the rear wheel is
dismounted.
For this purpose, lie the rear wheel on a work bench with the rear sprocket
upwards, and put the wheel spindle in the hub. Now hold the rear wheel firmly
and try to turn the rear sprocket. The rear sprocket may not turn more than
maximum 5 mm (0,2 in) measured on the outside. If the play in the chain
wheel is larger, all 6 shock damping rubbers are to be replaced.
Check the shock damping rubbers for signs of damage and dirt.
IF THE DAMPUNG RUBBERS ARE NOT REPLACED IN GOOD TIME, THE REAR
SPROCKET CARRIER AND THE REAR WHEEL WILL BE DAMAGED.
Tires, air pressure
Tire type, tire condition, and how much air pressure the tires have in them
affect the way your motorcycle rides, and they must therefore be checked when-
ever you’re getting ready to go anywhere on your motorcycle.
Tire type and size can be found in the technical specifications and in the homolo-
gation certificate.
Tire condition has to be checked every time you want to ride your motorcycle.
Before leaving check for punctures and nails or other sharp objects that might
have become embedded in the tire.
Refer to the specific regulations in your country for minimum tire tread require-
ments. We recommend replacing tires at the latest when the tread is down to
2 mm.
Tire pressure should be checked regularly on a „cold“ tire. Proper pressure
ensures optimum driving comfort and extends the life of your tires.
– DO NOT MOUNT TIRES WHICH HAVE NOT BEEN APPROVED BY KTM. OTHER
TIRES COULD HAVE ADVERSE EFFECTS ON THE WAY YOUR MOTORCYCLE
RIDES.
– THE FRONT AND REAR WHEEL ARE ONLY ALLOWED TO BE TIRED WITH TIRES
THAT HAVE THE SAME PROFILE TYPE.
– FOR YOUR OWN SAFETY REPLACE DAMAGED TIRES IMMEDIATELY.
– WORN TIRES CAN HAVE A NEGATIVE EFFECT ON HOW YOUR MOTORCYCLE PER-
FORMS, ESPECIALLY ON WET SURFACES
– IF AIR PRESSURE IS TOO LOW, ABNORMAL WEAR AND OVERHEATING OF THE
TIRE CAN RESULT.
– NEW WHEELS HAVE A SMOOTH SURFACE, WHICH MEANS THAT THEY MUST
BE RUN IN TO ACHIEVE FULL GRIP. FOR THIS PURPOSE, RIDE THE MOTOR-
CYCLE CAREFULLY AT MODERATE SPEED DURING THE FIRST 200 KILOMETERS
WITH NEW TIRES, TILTING THE VEHICLE AT DIFFERENT ANGLES SO THAT ALL
SECTIONS ARE PROPERLY ROUGHENED. TIRES WILL NOT DISPLAY THEIR
FULL GRIP CHARACTERISTICS UNTIL THEY ARE PROPERLY RUN IN.
– FOR REASONS OF SAFETY, IT IS RECOMMENDED TO EXCHANGE THE VALVE
INSERT WHENEVER A NEW TIRE IS MOUNTED.
