Polini's HI-SPEED variators for 50cc engines are now also available as extensive variator kits. 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
