RED FILTER more oxygen to the engine The quality which confirms the success Too often we neglect the simplest and most obvious component of our engine, whereas minor modifications increase efficiency, improve performance and extend service life of the engine. Let's consider for instance the fuel system, which supplies the "burst" of air and petrol that is closely related to the engine's performance. The filter task is of vital importance. In fact, on one hand it must prevent any impurity (which could cause serious damage in short time) from getting into the engine; on the other hand it must…

BIG BORE Testa Rossa 94 cc The new generation BIG BORE engine! Stud bolts, only for liquid-cooled scooters (7 ports and exhaut crossbar - piston with 1 segment - modular head - required boring of original case or C-One Malossi case - engine shaft with connecting rod different from the original). Deriving directly from seven port technology, which animates the revolutionary Flanged Mount, BIG BORE Testa Rossa cylinders represent the latest success achieved thanks to the efforts and studies that Malossi has continued to devote to engines intended for original Piaggio and Yamaha cases and, with…

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…

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…

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…

ALUMINIUM Ø 65 CYLINDER KITS Malossi aluminium cylinder kit: the best balance between component performance and life of the component. The aluminium cylinder kit produced by Malossi s.p.A. is designed and manufactured with the specific objective of obtaining high combustion efficiency, long life, and a reliability that suits the Malossi name. Owing to the experience gained in the preparation of cylinder kits for race, Malossi engineers have developed the thermodynamics of aluminium cylinder kit to the fullest and designed the inner fuid mechanics of the cylinder kit with fanatical precision…

The Malossi 180 H2O cylinder kit was born from years of direct development in competition, on the same scooters for which it was originally designed, the Gilera Runner . It's the component for you if you want to convert a 125cc liquid-cooled 2-stroke engine into a 180cc one. Reliable and robust, it ensures effective thermal dissipation even under prolonged stress, keeping the engine at constant temperature and performance over time. The geometry of the head – completely redesigned with a truncated cone dome with a central spark plug, an enlarged exhaust duct, and a third transfer port open at…
