10.18Checking 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, bearings
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 necessary.

Info
The upper chain section must be taut.
Chain wear is not always even, so you should repeat this measurement at differ-
ent chain positions.
Chain tension 35… 40 mm (1.38… 1.57 in)
» If the chain tension does not meet specifications:
– Adjust the chain tension. ( p. 90)
