Piaggio Malossi Primary Gear Up Kit 15/38


Add to Basket

Malossi primary gear kit for Piaggio 50cc scooters produced 2000 onwards.

Malossi is pleased to offer its new series of transmission gears for scooters, These new gears were created by exploiting 20-years 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, These gears increase ratios slightly enabling you to exploit the full power of your scooter, thus significantly increasing its original performance potential.

15/38 teeth.
This will increase standard gearing by 40% (except on Piaggio Zip)

On Piaggio Zip this will increase standard gearing by 30%.

You would need at least a mid-race setup to run a gearup kit this tall!
