Primary gears HTQ Malossi S.p.A. is pleased to offer its new series of final transmission gears. These new gears were created by exploiting our 20-year experience in designing and building gears. The new HTQ gears were designed and built with straight/helical teeth to minimise losses through friction and stress on the supports. Moreover, our gears increase ratios slightly enabling you to exploit the full power of your vehicle, thus significantly increasing its original performance potential.

PRIMARY GEARS WITH FLEXIBLE COUPLING 6716313 z 27/69 6717308 z 24/72 The power generated by an engine, whether standard or elaborate, will end in itself if it is not transmitted to the wheels in the most efficient and effective manner, without unnecessary friction and a waste of mechanical energy. Malossi, a leader in the production of high performance components for the world of motor scooters, has concentrated all its know-how in completely redesigning the primary transmission for the classic “small frame” Vespa, to ensure that maximum power is turned into road performance. The new Malossi…

Malossi is pleased to offer their customers its new final transmission gear assembly... THIRD SUPPORT Malossi, always attentive to rider's observations and requests, has focused on Minarelli-Yamaha, considering the CVT system has shown some deficiencies. At high RPMs, the driven pulley generates strong vibrations and oscillations to the primary gear shaft. To remedy this problem, an additional bearing, inserted into the original crankcase cover is used creating a third support for a redesigned longergear shaft. This modification prevents the gear shaft from flexing thus allowing the CVT…

Malossi is pleased to announce a new rear wheel axle, completing the set of primary and secondary gears! This rear wheel axle is a result of Malossi's twenty years of experience in gear designing and production for road and racing scooters. The rear wheel axle was designed and manufactured to be assembled into the original gear box without any modifications. The Malossi engineers have worked to reduce the rotating masses, hollow the wheel axle and increase rigidity and strength of the axle. Ideal match: MHR gear box cover, exaggerated performance! Technical Specifications Material: special…

Transmission gears made of special steel with straight teeth and recalculated ratio. They completely eliminate all the axial pressures, thereby reducing stress on the bearings. They are constructed using high-precision machine, casehardened, tempered and ground to provide silent running and long life.

Primary gear shaft We went as far as modifying the primary gear shaft to accommodate a pulley and clutch/bell assembly derived from the scooter world. Having become the connecting element between the newly designed components, this shaft has been reinforced with an increase in the shaft Ø to 13.5 and is supplied with a nut, oil seal and roller shell for mounting. Attention: in order to fit the primary gear shaft included in the kit, it is necessary to have fitted Malossi primary gears art. ( 6718630 out of prod.) or 6719286 or 67 7021 .

Ruote eseguite con acciaio speciale da cementazione, le ruote sono ottenute con macchine dentatrici al CNC e le ruote sono rettificate nelle superfici di contatto. Nelle superfici di contatto tra gli ingranaggi abbiamo ottenuto delle piccole sacche utili al trasporto dell’olio per aumentarne e garantire la lubrificazione tra le pareti che scorrono tra loro. I numeri di denti sono stati calcolati per dare un rapporto di trasmissione ottimizzato. In tutte le ruote dove era possibile eseguirli sono stati praticati dei fori di alleggerimento tranne che nella zona di sezione di contatto tra ruota…

VESPA SMALL FRAME GEAR CLUSTER AND GEARWHEEL KIT Although it shares several elements with the motorcycle world, such as the gears, the Vespa can be considered the forefather of the scooter, yet it poses a number of challenges. Lacking a conventional front and rear sprocket, the Vespa does not allow for the variation of its wheelbase. This makes it complicated to carry out any necessary modifications to support every performance increase – with the correct final drive ratio. Initially, at Malossi, we sought a solution by creating a new gear kit that coupled with the stock components ( art.…
