The new complete cylinders for 50-250 4t engines complete with control unit are born! Force Master is the innovative control unit that allows you to vary the injection to perfectly adapt to the new thermal group 4 stroke Malossi. This control unit has been programmed with different mappings so that it can be perfectly matched to your vehicle, sia and its configuration! Complete cylinder I-Tech 4 Stroke Material: primary aluminum alloy with ad high reclaimed silicon content, barrel with silicon carbide carry-over in a galvanic nickel matrix and cross-sanding with two diamond passages with very tight tolerances. Machining: su machines with numerical control ad high precision. Piston cylinder couplings in selection of 0.05 mm Heat exchange surfaces recalculated and increased Central Force Master Carburetion adjustment +-20% per min/med/max Rpm limiter: +1000RPM 4 different super compact Piston mappings 3-segment material: special primary alloy of aluminum to low thermal latation silicon with distal on the sliding walls Machining su numerically control machines Lightened and reinforced Heat exchange surfaces increased Segments • Special ad high sliding and ad very high mechanical resistance. • I. compression segment in nitrided and chromed steel. • II. special cast iron segment. • Oil scraper in three pieces in special bonded and chromed steel.
