10/REAR WHEEL 51
12.6Checking the chain tension - installing rear wheel
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) are under additional load. Apart from premature wear, in extreme cases the chain can
rupture or the countershaft of the transmission can break. On the other hand, if the chain is loose, it can fall off the engine
sprocket or the rear sprocket and block the rear wheel or damage the engine. Check the chain tension and correct if neces-
sary.

– Make sure that the chain adjuster support plates are lying on the adjusting screws.
– Push the chain at the end of the chain sliding component upward to measure the
chain tension .
Info
The upper chain section must be taut.
Because chain wear is not always even, repeat this measurement at differ-
ent chain positions.
Chain tension 5… 8 mm (0.2… 0.31 in)
» If the chain tension does not meet specifications:
– Adjust the chain tension when installing the rear wheel. ( p. 52)
12.7Checking rear sprocket / engine sprocket for wear
400227-01
– Check rear sprocket / engine sprocket for wear.
» If the rear sprocket / engine sprocket are worn:
– Replace rear sprocket / engine sprocket.
Info
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.
– Check the chain guide for tightness and wear.
