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…

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.

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…

Thus, the Over Range is renewed as well: new variator and new belt! This new system is based on Multivar MHR Next , which ? matched with the other parts - allows to achieve really unique performances! The torque driver (movable pulley) has a larger diameter compared to the original one and the very latest specifications, allowing to have a greater velocity-ratio range compared to the original pulley. 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…
