Malossi MHR Replica Cylinder Kit 77 ccm for Minarelli AM – Aluminum Racing for Strong Performance

The Malossi MHR Replica is a 70ccm aluminum racing cylinder whose performance level can be well compared to the Polini Corsa. The big advantage: unlike the Corsa, the MHR Replica is made of aluminum – this gives you significantly better thermal properties, as aluminum dissipates heat noticeably better than gray cast iron.

Durability is ensured by the hard-chromed nickel-carbon-silicon bore, which is designed for a long service life. To ensure the internal cooling is correct and you get a clean performance output, you should run at least a 17.5 mm carburetor.

The setup also fits when choosing an exhaust: the Stage6 Pro or the Nardo from Top Performances are recommended. A Yasuni C16 revs out far, but does not deliver the same peak values.
