or loss of life.
WARNING

The use of any nonstandard parts, including fasteners, could result in
serious injury.
WARNING
Do not exceed the Gross Vehicle Weight Rating of your motorcycle.
The Gross Vehicle Weight Rating (GVWR) is shown on the information
plate, located on the frame Down tube. (GVWR is the sum of the weight
of the motorcycle, accessories, and the maximum weight of the rider,
passenger and cargo that may be safely carried.) Exceeding GVWR may
lead to instability of the motorcycle, which could cause an accident and
result in serious injury.
