The MHR Replica is a fully-fledged racing cylinder, made of aluminium with a state-of-the-art ceramic coating.

Thermally the aluminium cylinders are far superior to their grey cast iron counterparts. The ultra-hard Nikasil coating ensures a long service life of the kit.

According to Malossi's manufacturer's statement, the cylinder compressed at 13.8:1 has 6.6 KW at 8,500 rpm. At this performance level a carburetor and exhaust should be installed.

A carburetor with at least 17.5 mm should be installed to ensure sufficient internal cooling of the cylinder.

The MHR cylinders are the result of years of intensive testing on the race tracks of the Scooter Trophy and thus offer full performance and excellent durability.
