Technical data Material: alluminium Cooling: air Bore: 39 mm Stroke: 41,8 mm Capacity 49,9 Compression ratio: 12.5:1 Timing system : 6 ports

Technical features 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 silicon carbide on a…

After much success with Piaggio crankcases, Malossi completes the task: Aluminium Ø 47 BIG DEPS Cylinder and Head Kits are now available again! The only CIAO/SI cylinders on the market with a split exhaust port and symmetrical transfer ports!!!! Threaded type exhaust header offers two major advantages: Increased strength and the possibility for replacement due to failure. Possibility to increase the exhaust size hence increasing the performance. These results are possible due to a smaller decompression valve, compared to the Piaggio original, which is supplied with the kit. Centred,…

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…
