Chain
Lubricating chain
Dirt, dust and inadequate
lubrication will result in ac-
celerated wear and significantly
shorten the drive chain's useful
life.
Clean and lubricate the drive
chain at regular intervals.
Lubricate the drive chain every
five operating hours at the
latest. Lubricate the chain
more frequently if the motor-
cycle is ridden in wet, dusty or
dirty conditions.
Switch the ignition off and se-
lect neutral.
Clean the drive chain with a
suitable cleaning product, dry it
and apply chain lubricant.
Wipe off excess lubricant.
Checking chain tension
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Turn the rear wheel until it
reaches the position with the
lowest amount of chain sag.
