After much success with Piaggio crankcases, Malossi completes the task: Aluminium Ø47 BIG D.E.P.S. 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,…

VESPA NEVER DIES Aluminium cylinder kit Ø 68,5 Afurther upgrade for the timeless Ø 68.5 cylinder kit! 1983 The aluminium cylinder with 68,5 mm diameter - turning point in Vespa tuning - was born. Made of Nicasil aluminium, with super light piston and 1.2 mm semi trapezoidal rings, it becomes a legend, a real musthave for all Vespa fans. 2008 The cylinder is updated, by adding the head with hemispherical combustion chamber and central spark plug. 2013 The cylinder, always made of Nicasil aluminium, has been completely changed concerning both main and rear ports and exhaust port as well.…

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…

CAST-IRON CYLINDER KITS Malossi is glad to present the new line of cylinder kits which have been designed for the latest generation scooters. They are unique tools able to defeat the traffic black-out of our cities. They are highly reliable and they have an exceptional torque. They have been studied to support a prolonged stress and can offer high accelerations even on highly pendent roads. They do not know neither fatigue nor wear.
