Polini 70cc Corsa cylinder for Piaggio AC

The POLINI 70cc CORSA is the factory-tuned version of the 70 Sport. The CORSA not only offers all the advantages of the Sport, it also plays an important role in the very sporty Midrace class.

Compared to the Sport, the timing has been raised significantly, the compression has been increased and the polished exhaust is a feast for the eyes. This allows the CORSA to mobilize up to 3 hp more. With the right components, the CORSA achieves rear-wheel outputs of up to 11 hp.

In addition to a racing shaft, a carburettor with a 19 mm passage and a suitably designed racing exhaust are recommended to enjoy the power over the long term. Due to the higher power output, the CORSA requires a bit of tuning work, but this will pay off in full and catapult you into the seventh heaven of the mechanics.
