They are of high quality and feature an optimised ramp design. Furthermore, every kit includes a torque spring that prevents belt slip and thus ensures better power transmission. The really cool thing is, however, the evo slider, a kind of guide plate that tackles the problem of twisting torque springs. Depending on which kit you get, there may also be a set of reinforced clutch springs included that will make the clutch engage later. Scope of delivery: variator, drivebelt, 2 torque springs, 2 sets of weights (5.6 + 6.9g), 1 set of clutch springs\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Polini\u003c\/li\u003e\n\u003cli\u003eSKU: U241.670.2\u003c\/li\u003e\n\u003cli\u003eAvailability: In stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNotes and Safety Polini Hi-SpeedThe famous Polini brand lists their \"Hi-Speed\" CVT as part of their catalog for many years.
