BIG DEPS 4 MHR Ø 47 Cylinder kit The cylinder draws its peculiar characteristics from the BIG DEPS range: the same aluminium alloy, barrel with nickel-chromium coating, the same redesigned central core and identical ring washing strategy. The support surface in the front part of the cylinder continues to be worked with high precision diamond tools and has 4 holes for fixing of the exhaust flange. The result has translated into a further and significant increase in performance! Finally, the most reliable and safe strategy of coupling and centring between cylinder and head has also been applied…

Fun without complications (6 transfer ports – 2 ring piston) Malossi cast iron thermal units, the first and simplest step to modifying your motorcycl’s engine, are the best choice for continued use of the exhaust system of an approved series or type . For these thermal units, the elevated feature of durability of cast iron is combined with the almost manically high quality standards of Malossi, one of the few companies to demand the most from even this class of thermal units. Into this is inserted the most rigid selections for the joining of the cylinder and the piston, strictly maintained…

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…

CAST-I-CYLINDER KIT Ø 63 CYLINDER The cylinder has a bore of 63 mm with a displacement of 178 cc and completely revised internal fluid dynamics. New port mapping allows for a high degree of coupling both with linked sumps and with completely new sumps, and includes a special profiling designed to optimise flow and obtain significant increases in performance, without the need to carry out any additional work on the vehicle. TRANSFER PORTS The transfer ports have a profile designed to correctly orientate the incoming flow and obtain a high degree of turbulence, thus ensuring improved combustion…

CYLINDER KIT MHR TECHNICAL FEATURES CYLINDER Material: special aluminium alloy with high percentage of silicon and titanium that guarantees exceptional strain strength even at high temperatures. Heat treatment: special quenching and stabilizing treatment that gives the material increased toughness and strength, guaranteeing that mechanical and size specifications will remain unaltered for temperatures of up to 250 °C. Chip-forming machining: carried out on NC machining centres with extremely-limited size and shape tolerance (roundness, perpendicularity). Inner surface coating: effected using…

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…
