Description
[Product Description]
The center spring of a two-class scooter is designed for a two-seater drivetrain,
Too stiff center spring will be a resistance for one rider and tuning of each part.
1: When shifting gears, the shape and angle of the torque cam groove determine the shifting characteristics, and it is the job of the center spring to apply the optimum tension to the belt during shifting.
Excessive hardness of the center spring will cause extreme reduction in maximum speed.
2: It is to push back the gearshifted torque cam to the low speed side when the accelerator is turned off.
It is closely related to the groove angle.
The reaction force (groove angle) on the gearshift side is also effective when returning.
The longer you sleep, the harder it is to get back to the center.
3: When accelerating, the belt grip is secured by the reaction force of the torque cam and the belt clamping force of the center spring.
If belt slippage does not occur in various driving situations, the hardness of the belt is sufficient, and increasing the hardness more than necessary will cause resistance.
Please select the rate to make the drivetrain more dynamic depending on the stage of driving and the specification of the engine.
Check the belt grip of pulley side and torque cam side, and change the center spring hardness according to the engine specification and riding condition.
