SUSPENSION SYSTEM
The suspension system (both front and rear) is the fundamental ingredient in determining the handling capability of a
motorcycle. The suspension system is responsible for keeping the wheels on the ground and absorbing the shock as
the motorcycle passes over uneven surfaces in the road. Both the front suspension (telescoping front forks) and the
rear suspension (rear swing arm and shock absorbers) operate by compressing and extending as the motorcycle
passes over a bump, absorbing the shock of the bump to keep the motorcycle stable. The front and rear suspension
utilize springs for the up and down compression and extension, and suspension dampers to stabilize the up and down
movement. Without the suspension dampers, the springs in the suspension system would continue to bounce up and
down after each bump creating a "rocking horse" or “pogo” effect.
Vengeance Motorcycles uses telescopic front fork assemblies. Each assembly consists of two fork tubes which
contain springs, spring dampers and oil. The fork legs slide on the fork tubes, and the tube or leg extends and
compresses within itself as a shock absorber. The triple trees and fork stem hold the front fork tubes to the frame and
keep the tubes aligned. The fork stem is an integral part of the triple tree and fits through the steering head allowing
the forks to be turned to the right and left, and limited by internal stops.
The Vengeance Motorcycles rear suspension system is configured with hidden shock absorbers (on solid-mounted
powertrain models) or external shocks (on rubber-mounted powertrain models). The hidden shock absorbers are
located underneath the powertrain and are constructed of a spring mechanism in a container with a shaft at one end
and a frame mounting collar at the other. These shock absorbers are set at the factory and should be replaced with
new components when worn. External shock absorbers can be adjusted for dampening and rebound settings by a
qualified technician.
Vengeance Motorcycles are designed to operate with one driver and optionally, when properly equipped, with one
passenger riding directly behind the driver. The addition of accessories, additional weight loads, etc. has not been
taken into consideration in the vehicle design and must be strictly avoided.
