Half belt pulley Ventilvar from Malossi
DESCRIPTION:
It is a fixed half pulley with a diamond surface of the pulley on the belt side and a redesigned working angle to further increase the transmission range. This component completes the Multivar and makes it incomparable. It has been specifically designed for the range of variable speed drives for scooters and further improves the performance of the drive belt. It is not just a simple accessory, but a very important component that guarantees the longevity of all transmission components. The temperatures generated in the crankcases of variators working with V-belts are intolerable at critical moments, and certain parts such as drive belts and variator pulleys sometimes suffer irreparable damage. There are cases where the rollers can even reach the melting point. The Ventilvar has, among other advantages, a higher cooling capacity than the original half pulley, which makes it indispensable for safe and sporty riding.

Malossi is one of the best-known brands in the scooter and motorcycle tuning sector. Since its foundation in Bologna in 1930, the Italian manufacturer has stood for uncompromising performance, innovative technology and a wide range of tuning parts. Whether cylinder kits, variomatics, clutches or exhaust systems - Malossi supplies everything that scooter and motorcycle riders need for more power, acceleration and riding enjoyment. Especially in racing and scooter tuning, Malossi is synonymous worldwide with quality and motorsport DNA.
Why Malossi is the first choice in tuning
- ✅ Italian engineering - developed with decades of experience in motorsport.
- ✅ Wide range of products - from basic tuning to high-end racing components.
- ✅ Quality & durability - robust materials and precise manufacturing.
- eCE-compliant parts - many components with road approval.
- ✅ Racing technology - parts derived directly from racing.
The most important product groups from Malossi
Cylinders & Big Bore Kits
Malossi is famous for its cylinder kits, which are available in various performance levels. From sports cylinders for everyday use to the MHR (Malossi Hyper Racing) kit for racing. These kits are made from high-quality aluminum, offer precise liners and high cooling capacity. Particularly popular: the 70cc cylinders for scooter riders who want maximum acceleration and speed. In combination with a reinforced crank drive and suitable components, they develop their full power.
Variomatic transmission & drive components
Another classic is the Malossi Multivar. This variator ensures better acceleration, smooth power transmission and a sportier response. The range is complemented by Kevlar drive belts, weights, overrange kits and clutches such as the Delta Clutch. Together they form a perfectly tuned drive system for everyday use, tuning or racing.
Exhaust systems
Malossi also offers sports and racing exhaust systems that are perfectly matched to the engine characteristics. They improve the exhaust gas flow, increase performance and provide the unmistakable racing sound. Especially in combination with cylinders and carburetors, drivers get the maximum out of their engine.
Clutches & centrifugal force systems
The Delta Clutch is one of the best-known clutches in the tuning sector. With adjustable springs and linings, it allows perfect tuning to individual requirements - whether for sporty road use or racing. In conjunction with Malossi bells and reinforcements, a durable, high-performance clutch system is created.
Carburetors & intake systems
Malossi supplies a wide range of carburetors, intake manifolds and air filters. These components enable optimum mixture formation and are essential for every tuning setup. A larger carburetor in combination with open air filters is a must, especially for performance-enhanced engines, in order to exploit the extra power.
Electronics & control units
Modern scooters often have electronic control units. Malossi offers CDIs, control units and electronic modules that remove the rev limiter or optimize the ignition. This allows engine characteristics and power delivery to be specifically adapted.
Crankshafts & internals
Malossi supplies reinforced crankshafts, connecting rods and bearings for high-end setups. These are developed for the high speeds and loads of racing engines. This creates the basis for reliable and stable high-performance engines.

Malossi Sport
The Sport line offers tuning parts that remain suitable for everyday use but enable significantly better acceleration and top speed. Ideal for riders who want more power without sacrificing reliability.
Malossi MHR (Malossi Hyper Racing)
The MHR series is designed for ambitious tuners and racers. High-performance cylinders, overrange kits and specially developed clutches bring maximum power to the road or race track. This series is the flagship of Malossi and a synonym for uncompromising racing.
