The advantage of grey cast iron is its very good resistance to heat and wear, even with intensive use. Together with the "Due Plus" this 80cc Polini "Sport" cylinder for Minarelli AM6 is probably one of the most powerful cylinders in the sport cylinder range, especially thanks to its high torque.

For more power we recommend to install a 19mm carburetor and a sport exhaust system.
