Adjusting the chain tension

Warning
Danger of accidents Danger caused by incorrect chain tension.
If the chain is too taut, the components of the secondary power transmission (chain, engine sprocket, rear sprocket, bearings in
the transmission and in the rear wheel) will be under additional load. In addition to premature wear, this can cause the chain
or the countershaft of the transmission to break in extreme cases. If the chain is too loose, however, it may fall off the engine
sprocket or rear sprocket and block the rear wheel or damage the engine. Ensure that the chain tension is correct and adjust it
if necessary.
Preparatory work
Raise the motorcycle with the rear wheel stand. (
Main work
Shift gear to neutral.
In the area of the chain sliding guard, press the chain upward toward the swingarm and
determine chain tension
