WORKING OF
NITROX REAR SUSPENSION
Function
• To suspend rear wheel to the frame with the
help of swinging trailing arm.
• To allow rear wheel to travel up and down
by absorbing shocks while passing through
ditches / bumps (comfortable ride for the
rider and pillion rider).
• To provide stability while graduating turns.
Advantage
The gas filled shock absorber enhances the
dampening performance by eliminating the
formation of foam. The foam formation is
eliminated by the nitrogen gas filled inside the
canister. The nitrogen gas is filled in canister at
a pressure which is 8 times greater than
atmospheric pressure.

Working : Gas Filled
Compression Stroke
In gas filled shock absorber, oil is completely filled in
inner, outer tube and canister. Nitrogen gas is filled in
membrane at a pressure of 6.5~7.5 Kg/cm .
During this stroke, oil flows freely from 'Upper Chamber'
to 'Lower Chamber' through piston valve. Simultaneously
oil also flows to canister assembly through base valve
and compresses the membrane filled with nitrogen gas.
At the end of the compression stroke, bump stop rubber
takes load and avoids hitting of lower eyelet mounting
against outer tube.
