12.5Checking 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) 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.
– Jack up the motorcycle. ( p. 7)
700483-01
– 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:
– Adjusting chain tension - after checking. ( p. 52)
– Remove the motorcycle from the work stand. ( p. 7)
