Variator-Kit -POLINI Speedcontrol- PGO 50 cc (type Big Max)

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.

Thus the smooth running of the Speedcontrol is in no way inferior to the top driving values.
