Maximized acceleration, higher RPM's and craftmanship of the highest caliber is what you can expect from the Malossi Multivar Variator kit. With years of tuning experience behind them, Malossi sought to design a way for all scooterists to benefit from their racing legacy and be able to tune and bolt on power quickly and easily.

Scooter West has been a proud distributor of Malossi products since 1995. We 
keep more Malossi part numbers in stock than any other company in North America. 
When it comes to quality performance scooter parts, MALOSSI is the long-standing 
industry leader for price, selection, and quality. All Malossi components are 
made 100% in Italy. All final manufacturing, assembly, and research and 
development is done at their impressive facility in Bologna, Italy. Literally, 
just down the street from Ducati and a 20 minute drive from Ferrari. The quality 
of Malossi components is commonly far superior to comparable original equipment 
components. They are after-all, designed and race-track tested and approved.

Like many other Italian aftermarket companies, Malossi has humble beginnings as 
a small family business sprung from one man's passion. Mr. Ugo Malossi started 
tuning and manufacturing the best performance carburetors in the region under 
the tutelage of his mechanically accomplished father, Armando. In 1957, with the 
vision of Ugo, Malossi was formally born. Ugo's son and daughter are the active 
managers of the company and they share in their father's passion and vision to 
“Always improve.”

being said, we wouldn't sell anything that we wouldn't install on our own 
scooters. We are blessed to have a Robot running our service department that 
makes sure everything is installed correctly on our personal scooters ;).
