Final Drive Belt

!
For safety and to prevent excessive wear the
drive belt must be checked, adjusted and
renewed in accordance with scheduled
maintenance requirements. Checking and
adjustment must be carried out more
frequently for extreme conditions such as
salty or heavily gritted roads.
If the drive belt is badly worn or incorrectly
adjusted (either too loose or too tight) the
belt could jump off the drive belt pulleys or
break. Therefore, always replace worn or
damaged drive belts using genuine Triumph
parts supplied by an authorised Triumph
dealer. The drive belt requires no lubrication.
