Welcome to! Your source for Rotax 2-Stroke self-start engines. The Rotax concept offers the karting enthusiast with a reliable world-wide engine platform program that offers level playing field competition and great performance. With a factory-direct motor warranty and official trained service centers throughout the country, Rotax engines provide more value than any engine package currently available in karting.

New Clutch & Balance Gears - NOW AVAILABLE! and associated dealers now have the all new centrifugal FR125 and DD2 clutch and balance shaft retrofit kits available and in-stock. The clutches are redesigned to improve durability, reduce maintenance costs and reduce rotating mass. The new gears are made of steel to make them longer lasting than the plastic gears they replace. NOTE: These clutches and gears are designed to be used together as the new clutch increases the load put on the gears reducing the life of the plastic gears.


Retrofit kits are available for both the FR125 engine (for Rotax Jr., Rotax Sr. and Rotax Masters classes) as well as DD2 engines. Individual parts will also be available by December 15, 2008.
