Checking 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 for correct chain tension and adjust if necessary.
- Jack up the motorcycle.
- Push the chain at the end of the chain sliding component upwards to measure the chain tension (A).
The upper chain section (1) must be taut.
Chain wear is not always even, so you should repeat this measurement at different chain positions.
Chain tension: 8… 10 mm (0.31… 0.39 in)
Adjusting chain tension – after checking
- Loosen nut (1).
- Loosen nuts (2).
- Adjust the chain tension by turning the adjusting screws (3) left and right.
Specification: Chain tension 8… 10 mm (0.31… 0.39 in)
Turn the adjusting screws (3) left and right so that the markings on the left and right chain adjusters are in the same position relative to the reference marks (A). The rear wheel is then correctly aligned.
- Tighten nuts (2).
- Make sure that the chain adjusters (4) are fitted correctly on the adjusting screws (3).
- Tighten nut (1).
Nut, rear wheel spindle: M20x1,5 80 Nm(59.01 lbf ft)
