Modifications
We strongly advise you not to remove any original equipment or modify your
motorcycle in any way that would change its design or operation. Such changes
could seriously impair your motorcycle's handling, stability, and braking,
making it unsafe to ride.
Removing or modifying your lights, exhaust system, emission control system, or
other equipment can also make your motorcycle illegal.
