Malossi MHR 70 cc - Racing cylinder for Piaggio 2-stroke AC

The Malossi Hyper Racingcylinder is a high-end cylinder developed in the Trophy Cup. As is typical for Malossi, the casting quality and coating are beyond reproach.

The surfaces of the ports and the timing have been specially adapted for racing use. With an output of up to 22 hp (16 kW) and speeds of up to 15,000 rpm, it goes without saying that Malossi uses only the best materials to manufacture these cylinder kits. As with the Evolution series from Polini, the MHR should not be seen on its own, but rather as a complete kit. After all, a tuning can only ever be as successful as the weakest link in the chain allows.

The MHR impresses with top workmanship, a beautifully divided exhaust (T-shape) and large overflow ducts to which the housing should be adapted.

The combustion chamber geometry is designed in such a way that a compression ratio of 15.8:1 can be achieved.
This is how we ensure, that reviews come from real consumers.
