Cylinder -MALOSSI 70 cc MHR- Minarelli (vertical) - BOOSTER, BUMP50, BWS50, SLIDER50, SPY, SR50 (-1994), STUNT, ZUMA50, AMICO
Part no.:

Description
The Malossi Hyper Racing cylinder is a high-end cylinder developed in the Trophy Cup. The casting quality and the coating are typically Malossi above any doubt.
The surfaces of the channels and the timing have been specially adapted to racing use. With an output of up to 22hp (16kW) and speeds of up to 15000 rpm, it goes without saying that Malossi uses only the best materials to produce these cylinder kits. Like Polini's Evolution series, the MHR is not to be seen alone but rather as a complete kit. Because a tuning can only be as successful as the weakest link in the chain allows it to be.
The MHR convinces besides the top workmanship with a nicely split exhaust (T-shape) and large overflow channels, to which the body should be adapted.
The combustion chamber geometry is designed in such a way that a compression of 15.8:1 can be realized.
