Checking the chain tension

Warning

Danger of accidents Incorrect chain tension damages components and results in accidents.

If the chain is tensioned too much, the chain, engine sprocket, rear sprocket, transmission and rear wheel bearings wear more quickly. Some components may break if overloaded.

If the chain is too loose, the chain may fall off the engine sprocket or the rear sprocket. As a result, the rear wheel locks or the engine will be damaged.

• Check the chain tension regularly.
• Set the chain tension in accordance with the specification.

Preparatory work

• Raise the motorcycle with the rear lifting gear.

Main work

• Shift the transmission to neutral position.
• Push the chain behind the chain sliding piece up and determine the chain tension A between the swingarm and the upper edge of the chain.

Guideline

Info

Top chain section C must be taut.

Chain wear is not always even. Repeat this measurement at different chain positions.

If the chain tension does not meet the specification:

• Adjust the chain tension.

Finishing work

• Remove the rear of the motorcycle from the lifting gear.
