Malossi I-TECH aluminum cylinder D 49 piston pin 10

The Malossi I-TECH 4-stroke complete cylinder Ø 49 in aluminum is a high-quality product that offers numerous advantages. Made with a primary alloy of bonified high-silicon aluminum, it features a barrel with silicon carbide overlay in a galvanic nickel matrix and a cross-honed finish with two diamond passes, ensuring high strength and precision. The machining is done on high-precision CNC machines, with cylinder-piston couplings selected with a tolerance of only 0.05 mm. The heat exchange surfaces have been recalculated and increased, ensuring effective heat dissipation.

The Force Master ECU is an innovative ECU that allows for injection variation to perfectly adapt to the Malossi 4-stroke thermal group. Programmed with different mappings, it can be perfectly matched to your vehicle, regardless of its configuration. The ECU offers carburetion adjustment with a variation of ± 6% at min/medium/max and a rev limiter that increases by 1000 RPM. In addition, there are 3 different mappings available to suit different needs.

The piston, made with a special primary alloy of low thermal expansion silicon aluminum with tin overlay on the sliding walls, is super compact and reinforced. The machining is done on CNC machines, ensuring high precision. The heat exchange surfaces are increased, ensuring effective heat dissipation.

Finally, the rings are special high-sliding and high mechanical strength. The first compression ring is made of nitrided and chromed steel, while the second ring is made of special cast iron. The oil scraper consists of three pieces of special alloyed and chromed steel.

These complete I-Tech 4-Stroke cylinders offer high performance and superior durability, thanks to their construction quality and advanced technical features.
