Performance and purpose of kit suspension (Differences compared with standard suspension on commercially available machines)
*Spring load: Depends on the stroke. Damping force: Depends on the stroke speed.
Spring characteristics
Commercially
available machine
specs
Purpose To increase comfort when riding in urban areas while
preventing bottoming even with two people on the bike.
Performance/characteristics
Combination of springs and bump rubbers.
Problem with circuit Easy to fully extend when braking. (high preload.)
Road-holding property of rear tire is easily lost during braking;
rear tire behavior (hopping, sliding, etc.) easily occurs.
Kit suspension specs Addition of a rebound spring near full extension alleviates the above problem.
Damping force characteristics
Commercially
available machine
specs
Purpose To maintain comfort when riding in urban areas and improve
road-holding properties when banking into bends.
Performance/characteristics
Limits reaction force to the minimum required damping load.
Problem with circuit Reduces machine stability. (excessive movement when
accelerating, passing over a gap, etc.)
Reduces turning performance (stroke volume is excessive
and the rear of the machine is lower than the front)
Kit suspension specs Limits excessive dipping by increasing the damping force on the compression side.
Others
Kit suspension specs Change in total length
Being assembled with a rebound spring, the kit suspension raises
the road-holding property of the rear tire when braking. (The total
length is changed according to the rebound spring setting.)
R1:293 mm (STD:290 mm)
R6:287 mm (STD:290 mm)
