"OVER RANGE" Malossi transmission system This new transmission system takes full advantage of the Malossi components already on sale last year, by adding several new parts that make the entire system particularly suited to the enormous power available. This latest system hinges on the new Fixed Pulley of the torque driver that has a larger diameter and the very latest specifications. The larger diameter of this pulley allows one to have a greater velocity-ratio range compared to the original pulley that has a notably smaller external diameter.

"OVER RANGE" Malossi transmission system
This new transmission system takes full advantage of the Malossi components already on sale last year, by adding several new parts that make the entire system particularly suited to the enormous power available. This latest system hinges on the new Fixed Pulley of the torque driver that has a larger diameter and the very latest specifications. The larger diameter of this pulley allows one to have a greater velocity-ratio range compared to the original pulley that has a notably smaller external diameter.
Malossi engineers have also taken particular care in realising this pulley right down to the smallest detail, using special materials and a particular type of thermochemical treatment that ensures exceptional surface hardness and therefore excellent wear and abrasion resistance. This new fixed pulley has been designed to offer perfect running if coupled to the Malossi Torque Driver that is already available and has the same diameter as the fixed pulley itself. In order to fully exploit the range of the new torque driver unit and the power ratings currently offered by competition machines, a new notched K Belt has been introduced with larger section and revised length to ensure maximum performance under all running conditions.
To complete the renewal of the transmission system and take full advantage of its exceptional specifications, the Multivar variable-speed drive has also been upgraded by fitting it with new tracks for the rollers and a new hub. This new variable-speed drive represents the evolution of the previous generations, the result of many years experience on the race circuit and the currently available CAD-CAM technology that allows top-level specifications to be obtained.
The whole completion of the OVER RANGE system is given by the patented adjustable clutch Delta Clutch and the Malossi reinforced clutch cap Wing Clutch Bell.

Data sheet
X K Belt Racing use Malossi X K Belt is the top of racing transmission belts! Made with hard-wearing materials combined with Kevlar® inserts. Malossi trapezoidal X K belts provide a very high thermal and abrasion resistance. Worthy exponents of MALOSSI HYPER RACING product range. they are the result of decades of experience and of search for absolute performance in the racing field.
NEW MHR VARIATOR for OVER RANGE for Minarelli - Yamaha engines The never-ending (incessant) power increase drove us to design (project) an extraordinary variator! The innovative elements of this new MHR variator for OVER RANGE are: - far better running (running further improved); - rollers from Ø 16x13 to Ø 19x15.5 , to grant a longer gear curve; - reinforced variator structure on bushing side, to allow greater stability and length in gear curve. No wonder then if with a variator that features such sophisticated engineering, your scooter suddenly has that extra sprint, a consistency in…
VENTILVAR 2000 It’s a fixed half-pulley with a diamond finish of the belt-side pulley surface and a redesigned working angle to further increase the gearing range. This component completes the Multivar and renders it unparalleled. Specially designed for the line of variable-speed drives for scooters, it further improves the performance of the drive belt. It is not just a simple accessory, but a very important part for guaranteeing the long life of all the transmission components. The temperatures produced inside the crankcases where variators work with V-belts are prohibitive at critical…
Half-pulley made of aluminium alloy with silicon content, machined on very high precision CNC machines and diamond-finished, with recalculated profiling of the roller sliding guides.
K-DRIVE MALOSSI Malossi K-DRIVE is a lighter gear ratio than the original for the Yamaha Tmax 530 - 560 . Characterised by a sought-after appearance, the K-DRIVE crowns and pinions have different ratios to satisfy all the rider’s requirements. Pinion 6118805B Z 25 6118804B Z 27 6118814 Z 28 6118815 Z 29 Crown 6118806B Z 60 TECHNICAL SPECIFICATIONS The pinions are made from aluminium with hard oxidisation 25 microns deep. With this treatment Malossi has maintained a particularly light shape of the piece whilst guaranteeing high wear resistance. The central hub is made from a special steel…

TORQUE DRIVER The mobile driven split pulley comes from our racing department's many years of experience, and is manufactured with the best possible special nitrided steels in order to ensure a long life. This component called Torque Driver for its specific function of determining the exact shifting moment, was calculated to give the vehicle the maximum possible acceleration in connection with the specific power of any single engine. The spiral's peculiar shape was studied to fix the RPMs on the point of maximum power. It was expressly created to complete the development of boosted motors…
