10/REAR WHEEL
Checking rear sprocket / engine sprocket for wear

Checking the chain tension

Warning
Danger of accidents Danger caused by incorrect chain tension.
–
If the chain tension is too high, the components of the secondary power train (chain, engine sprocket, rear sprocket, bear-
ings in transmission and rear wheel eccentric element) are under additional load. Apart from premature wear, in extreme
transmission output shaft or the drive chain may snap. Conversely, if the chain is too loose it may jump off the engine and
rear sprockets, causing the rear wheel to lock up or even leading to engine damage. Check for correct chain tension and
adjust if necessary.

–
Check that the chain guides are tight.
–
Park the vehicle on a horizontal surface and shift gears to neutral.
–
Push the upper chain section at the end of the chain sliding component upwards to
measure the chain tension
Info
The lower chain section must be taut.
Chain wear is not always even, so you should repeat this measurement at
different chain positions.

When fitting the chain joint, always make sure that the closed side
of the joint faces forward (riding direction).
The engine sprocket, rear sprocket and chain should always be
replaced together.
