Polini Corsa 70cc Cylinder Kit - Aerox/ Minarelli L/C


Add to Basket

The Polini Corsa 70cc kit makes approx 25-30% more power than the Polini sport. It's still cast iron which means it's very strong and can be rebored but runs at higher revs, very similar performance to the aluminium Malossi MHR rep kit

Realistically this is about the limit of what can be used with any degree of reliability for everyday use. As with the MHR rep 70cc kit the oil mixture should ideally be increased to 33:1 either by an adjustable ratio oil pump (see engine category) or by pre-mixing. Will also need a decent high end sports exhaust e.g. Yasuni R

An up-rated crankshaft is recommended with this kit.

Champion RN2C spark plug included (NGK BR9ES equivalent)

Fits... Yamaha Aerox/ Minarelli liquid cooled engines

This kit produces peak power at 11500rpm, Includes gaskets, spark plug.
