Pull on the upper part of the chain with the specified weight
.
Guideline
Weight, chain wear measurement
10… 15 kg (22… 33 lb.)
–
Measure the distance
of 18 chain links in the lower chain section.
Info
Chain wear is not always even, so you should repeat this measurement at
different chain positions.
Maximum distance
at the longest
chain section
272 mm (10.71 in)
» If the distance
is greater than the specified measurement:
–
Replace the chain.
Info
When you replace the chain, you should also replace rear sprocket
and engine sprocket.
New chains wear out faster on old, worn sprockets.
–
Remove the motorcycle from the work stand. (

Adjusting 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. (
