Description

The POLINI 70cc CORSA is the factory tuned version of the 70 Sport.

So not only does the CORSA offer all the benefits of the Sport, but it also plays a significant role in the quite sporty midrace class.

Compared to the Sport, the timing has been increased significantly, the compression has been increased and the polished exhaust is a feast for the eyes. Thus up to 3 HP more are mobilized with the CORSA. With the right components, the CORSA can reach a rear wheel performance of up to 11 hp.

In addition to a racing shaft, a carburettor with 19mm passage and a correspondingly designed racing exhaust is recommended to enjoy the performance permanently.
BR> Due to the higher performance, a little tuning work is necessary with the CORSA, but it pays off completely and catapults you into the 7th screwdriver heaven.
