The Polini +15% torque spring is a high-end CVT transmission component designed for scooters and motorcycles equipped with GY6 125cc to 150cc engines, such as the Honda Ruckus GY6, as well as certain Kymco and Honda platforms sharing the same CVT architecture.
In a CVT (Continuously Variable Transmission) system, the torque spring acts on the rear pulley (Torque Drive). It determines how and at what RPM the rear pulley reacts to the centrifugal force of the belt based on engine speed and load. The +15% calibration means this spring is 15% stiffer than an original torque spring, which:
slightly delays the closing force of the rear pulley,
allows the engine to remain more frequently within its optimal RPM range before the final drive ratio changes,
increases belt traction and stability under load.
This compromise is particularly useful when the machine:
