MHR REPLICA CYLINDER KIT The MHR Replica line of cylinder was created especially for the International Scooter Trophy - 70cc Automatic Class. These cylinder kits were designed to guarantee maximum performance in this category, while at the same time assuring extremely long product life. In order to guarantee these special characteristics, Malossi MHR Replica cylinder kit have pistons with two chrome-plated rectangular segmants and a compression ratio of 13.8:1, plus torque value of 7.35 N.m. (o.75 Kgm) at 8.000 rpm and power of 6.6 Kw (9 C.V.) at 8.500 rpm. The MHR line is the results of…

After being a protagonist for 30 years, the everlasting Ø 61 cast-iron cylinder kit, art. 31 4093, updates! Constantly refined over the years, the legendary Ø 61 has now a new code, after undergoing further upgrade concerning above all the main and rear transfer ports. It is the one and only cylinder kit of its kind using an o-ring as sealing gasket between head and cylinder, in order to guarantee better sealing and heat dissipation. By improving torque at low RPMs, this cylinder kit further increases performance. With this development Malossi technicians went beyond all expectations once…
