Drive Chain Damage Inspection
WARNING
If the drive chain is found to have
damaged rollers, loose pins or stiff
links, the drive chain must be replaced.
Do not attempt to loosen any stiff
links. The stiff link may have damaged
or worn components.
Riding with drive chain stiff links, or
loosened stiff links, may result in a
broken drive chain or may cause the
drive chain to jump off the sprockets,
leading to loss of motorcycle control
which could result in serious injury or
death.
▼ Rotate the rear wheel and inspect
the drive chain for damaged rollers,
loose pins and stiff links.
1. Stiff link
▼ If the drive chain has any damaged
rollers, loose pins or stiff links, the
drive chain must be replaced by a
competent person with the specialist
knowledge and technical
understanding of motorcycles, such
as an authorised Triumph dealer.
Drive Chain Wear Inspection
▼ Stretch the drive chain taut by
hanging a 10 - 20 kg (20 - 40 lb)
weight on the drive chain.
1. Measure across 20links
2. Weight
▼ Measure the length of 20 links on the
straight part of the drive chain from
pin centre of the 1st pin to the pin
centre of the 21st pin. Since the drive
chain may wear unevenly, take
measurements in several places.
▼ If the length exceeds the maximum
service limit, the drive chain must be
replaced. Refer to the Specifications
section for the maximum service
limit.
