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…

CYLINDER KIT Ø 63 ALUMINIUM completely new cylinder kit has been created, designed overall to obtain the maximum result in terms of performance and durability. Every aspect of the system has been studied to maximise the mechanical resistance, the fluid dynamics and improve combustion: the result is a top-of-the-range kit in terms of construction quality and technological development. TECHNICAL FEATURES Cylinder Built from scratch, in high-strength aluminium alloy and cylinder sleeve with nickel-chromium coating. Consisting of an even thickness central core around the cylinder sleeve and the…

Malossi, whose expertise in balancing a vast experience with the latest technology, embraced this new challenge: to bring to the racetrack a fuel injected two stroke engine. With the new INJECTION TECH range of products a new chapter is written, an answer, the racing world was anticipating, to satisfy the growing number of Malossi Trophy Races for 70cc scooters. Technical features Cast iron cylinder - Technology Material: special self-lubricating, wear-resistant, highly refined cast iron alloys, obtained by Shell Moulding gravity die-casting Machining: on numerically controlled high precision…

The most powerful thermal unit ever produced by Malossi: over 32 HP at 14,000 RPM. With its large displacement and flanged design, this kit is exclusively for liquid-cooled scooters. Specifically designed for top-level racing, it features the latest evolution of Malossi’s iconic 7-port technology. The standout feature is the support provided to the main rear transfer ports through the use of two ports opposite the exhaust, combined with the advantage of eliminating the space taken up by the through-studs, which are now shorter and positioned externally. This allows full utilization of the…

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 Malossi's many years of…
