Technical features 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 ports, a constant heat exchange is ensured, therefore, a controlled intake temperature of the gases in the chamber and an optimal heat exchange at the exhaust. It has aerodynamically profiled cooling fins around the core, designed to be penetrated with the best possible efficiency by the cooling air. The major innovation lies in the totally revamped and coated ports, introducing the latest CVF,…

After much success with Piaggio crankcases, Malossi completes the task: Aluminium Ø47 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,…
