Polini Cylinder Corsa 70cc Minarelli horizontal LC

This is the improved version of the Polini Sport 70cc cylinder.

Thanks to an optimized control timing, a polished outlet, and increased pre-compression, the Polini Corsa provides 2 to 3 HP more power than the Sport 70cc. 11.5 HP at 10,000 revolutions with a good adjustment of your bike.

The 2-segment piston (one metal and one chrome) has a special coating that makes it more resistant.
In order to take full advantage of the cylinder's power, we recommend a Sport or even Racing type exhaust such as the Stage6 PRO or the Polini for Race.
You must use a carburettor of at least 21mm. The standard one is not suitable.

Polini recommends fitting a br9es or a br9eg spark plug
