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. Cylinders made of selected lamellar cast iron alloys with recalculated cooling surface. Strengthened pistons made of aluminium alloys with high silicon content,…

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,…

The most powerful thermal unit ever produced by Malossi: over 32 HP at 14,000 RPM. With its large displacement and flanged design, this kit is exclusively for liquid-cooled scooters. Specifically designed for top-level racing, it features the latest evolution of Malossi’s iconic 7-port technology. The standout feature is the support provided to the main rear transfer ports through the use of two ports opposite the exhaust, combined with the advantage of eliminating the space taken up by the through-studs, which are now shorter and positioned externally. This allows full utilization of the…
