TENSIONING THE CHAIN
To ensure the drive chain a longer life, it is
advisable to periodically check its tension.
Always maintain the chain clean and lu-
bricated.
If the chain play exceeds 20 mm, tension
the chain by following these steps:
• Loosen the nuts on both arms of the rear
fork.
• Turn nut B until the desired chain tension
is obtained.
• Perform the same operation on nut B on
the other side of the swing arm until the
wheel is perfectly aligned.
• Clamp the counter-nut A on both arms of
the rear fork.
