General Frame Inspection; Bank Angle Indicators - Triumph Thunderbird Service Manual

Frame and Bodywork
General Frame Inspection
1.
Inspect the frame, bodywork and footrests for
accident and other damage, cracks, splits and
general dilapidation. Check all fixings for security. If
any faults are found, rectify as necessary. If any faults
with the frame are found, the frame must be
replaced; repairs to the frame are not permitted.
If the motorcycle is involved in an accident or collision it
must be taken to an authorised Triumph dealer for
inspection and repair before it is ridden again.
The frame must not be modified in any way. Any
modification to the frame, such as welding or drilling,
may weaken the structure causing an unsafe riding
condition leading to loss of control and an accident.
2. Check the operation of the side stand to make sure it
is securely held in the retracted position by the
spring. Rectify any faults.
If the return spring is faulty, the side stand could extend
whilst the motorcycle is being ridden. This will cause an
unsafe riding condition, which could lead to loss of
motorcycle control and an accident.
Bank Angle Indicators
1. Inspect the bank angle indicators on the rider's
footrests for wear. The bank angle indicators are
worn out when 5 mm of the bank angle peg
remains.

Bank Angle Indicators
Use of a motorcycle with bank angle indicators worn
beyond the maximum limit (when the bank angle
indicator is worn to a minimum 5 mm in length) will
allow the motorcycle to be banked to an unsafe angle.
Therefore, always replace the bank angle indicator pegs
when they are worn to 5 mm in length.
Banking to an unsafe angle may cause instability, loss of
motorcycle control and an accident.
The bank angle pegs must not be used as a guide to
how far the motorcycle may be safely banked. This
depends on many various conditions including, but not
limited to, road surface, tyre condition and weather.
Banking to an unsafe angle will lead to loss of
motorcycle control and an accident.
