WMI Racing Development is a full service race shop. We specialize in motor modifications and custom suspension tuning for Honda, Yamaha, Kawasaki, Suzuki and KTM. We can also build you a complete race-ready bike.

You have probably seen us at the amateur nationals throughout the country. We travel to all the nationals because the only way to stay on top of the podium is to go head to head with the competition each week. After a race is the best time to analyze your equipment and perfect it for the next competition.

WMI MX is the official motor/suspension shop for the Butlerbrothersmx supercross race team.
