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,…

BIG DEPS 4 MHR Ø 47 Cylinder kit The cylinder draws its peculiar characteristics from the BIG DEPS range: the same aluminium alloy, barrel with nickel-chromium coating, the same redesigned central core and identical ring washing strategy. The support surface in the front part of the cylinder continues to be worked with high precision diamond tools and has 4 holes for fixing of the exhaust flange. The result has translated into a further and significant increase in performance! Finally, the most reliable and safe strategy of coupling and centring between cylinder and head has also been applied…

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…
