STAGE 1 TUNING KIT COMPONENT

These new gears were created by exploiting our 20-year experience in designing and building gears for competition and road scooters. The new H.t.q. gears were designed and built with straight 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 scooter, thus significantly increasing its original performance potential.

STAGE 1 TUNING KIT COMPONENT

The new range of MHR REPLICA exhaust systems has been studied by CAD systems and defined for all types of 50cc scooters.
The engineers at Malossi Engineering R&D Department have improved the vehicle’s performance according to laws, after strict testing with sophisticated and modern equipment at Malossi Engineering’s test department.
The MHR REPLICA exhaust systems address a sporting and demanding customer; they personalise your scooter with elegance and with a “performance sound”, completing the thermodynamic cycle of the famous Malossi MHR REPLICA cylinder kit.
