Check chain tension

Park the motorcycle on the side stand and switch off the engine.
Chain tension has to be checked close to the lower rear shock mounting A.
When pushing the chain upwards, the distance to the swingarm has to be 10
mm (0.4 in).
If necessary, correct chain tension.
10 mm
– IF CHAIN TENSION IS TOO GREAT, PARTS WITHIN THE SECONDARY TRANS-
MISSION (CHAIN, CHAIN WHEELS, GEAR BOX AND REAR WHEEL BEARINGS)
WILL BE SUBJECTED TO UNNECESSARY STRESS, RESULTING IN PREMATURE
WEAR AND EVEN CHAIN BREAKAGE.
– TOO MUCH SLACK IN THE CHAIN, ON THE OTHER HAND, CAN RESULT IN THE
CHAIN JUMPING OFF THE CHAIN WHEELS. IF THIS HAPPENS, THE CHAIN COULD
ALSO BLOCK THE REAR WHEEL OR DAMAGE THE ENGINE.
– IN EITHER CASE THE OPERATOR IS LIKELY TO LOSE CONTROL OF THE MOTOR-
CYCLE.
– BE CAREFUL NOT TO GET YOUR FINGER CAUGHT BETWEEN THE CHAIN AND
THE REAR SPROCKET OR OTHER COMPONENTS.

Correct chain tension

Release the hexagon nut of the wheel spindle [1] and turn the left and the
right hexagon nut [2] equally far.
Before tightening the hexagon nut of the wheel spindle to 40 Nm, ensure that
the supporting plates [3] are resting against the swing arm. Additionally,
check that the rear wheel is aligned with the front wheel.

Chain maintenance

For long chain life, good maintenance is very important. Chains without
O-rings should be cleaned in fireproof solvent regularly and afterwards
treated with hot grease or chain spray (Motorex Chainlube 622).
KEEP THE REAR WHEEL FREE OF GREASE! GREASE ON THE REAR WHEEL WILL
SIGNIFICANTLY REDUCE THE GRIP OF THE REAR TIRE AND THE MOTORCYCLE COULD
EASILY GET OUT OF CONTROL.
WHEN MOUNTING THE CHAIN MASTERLINK CLIP, THE CLOSED SIDE OF THE MAS-
TERLINK CLIP MUST POINT IN RUNNING DIRECTION.
Also check sprockets and chain guides for wear, and replace if necessary.
