Polini Aluminum Cylinder 70cc Minarelli vertical

This is a powerful aluminium cylinder, manufactured by GILARDONI.

The key advantage of aluminium cylinders is their resistance to high temperatures. Thanks to the chromed running surface, both the piston and the cylinder last longer.

The 70cc aluminium is a reliable cylinder suitable for daily use, allowing you to reach around 10-11 HP of power.

We recommend a carburettor of at least 17.5mm.

Polini recommends a BR9HS spark plug
