ISRT is a professional Supercross and Motocross race team based in Edwardsville, Illinois. Bubba Pauli, who competed professionally for 13 consecutive seasons, founded the team in 2017. ISRT showcases athletes and partners from the United States and around the world.
ISRT has proudly been equipped with Kawasaki motorcycles from Southeast Sales Powersports for numerous years. Southeast Sales, a Kawasaki dealership in Milwaukee, Wisconsin, continues to power the team today.
Built on faith, strong values, integrity, and hard work, ISRT was created to be more than just a race team. Following his retirement at the conclusion of the 2025 season, Bubba set out to take ISRT to the next level—building a team capable of competing at the highest level of professional motocross.
Winning is only part of the mission. ISRT is committed to building the right culture, treating people the right way, and remaining true to the values and faith that have shaped the organization from the beginning.
We compete to win. We lead with purpose. We represent something bigger than ourselves.
