Fox + Son is, hands down, the top Rotax builder in North America. Fox built Rotaxes dominate every category and send drivers to the Rotax World Championships every year. We have spent years of research on the dyno and the track to get every ounce of power from the Rotax powerplant, and with National and Regional championships every year, our results speak for themselves.

The Rotax concept is unique: with simple, reasonably priced upgrades, you can use the same engine all the way from Micro Max to Senior Max. Besides the parts, the only engine work required to move a Rotax up though the classes is a simple reset of the squish gap and replacing the cylinder when moving up to Senior. In the Rotax tuning section you will find information regarding what is required to upgrade an engine from one class to the next.
