With the SPEED CONTROL, Polini offers a sophisticated system that, in combination with a de-throttled engine, gives very good results.
In some combinations you can increase the top speed up to 15 km/h, with much better acceleration.
Polini has spared no effort and has done an enormous development work. The result is a High Tech Vario with newly calculated and hard chrome-plated tracks for the rollers, self-lubricating slide bush made of sintered steel and a hub made of high quality alloyed steel. The half disk consists of a high-quality silicon-aluminum alloy.
Thereby the running smoothness of the Speedcontrol is in no way inferior to the top riding values.
The 500cc motors use the enclosed 14gr. Weights, the 400cc version requires 12gr for optimal performance. Weights (25x17mm)
