King of the Baggers Cuts Traction Control and Caps Revs
Share
Big changes are coming to King of the Baggers here in the U.S. for 2027. MotoAmerica President Wayne Rainey shared new structural and technical regulations that will alter how these heavyweight race machines run.
Rider aids are taking a backseat. Full-season entries will run a standardized Maxx ECU Race control unit with locked firmware. That setup strictly prohibits traction control and lift control. To improve engine reliability and lower rebuilding expenses, MotoAmerica is also capping motor speeds. Harley-Davidson engines get a rev cap fixed at 7,000 rpm, while Indian engines are limited to 7,500 rpm.
The grid is also opening entry to additional manufacturers. Indian Motorcycle has already locked in a larger paddock and grid presence, committing to field more machines for 2027. King of the Baggers has quickly become one of the most popular road racing classes in the country, putting heavily modified American V-twins head-to-head on high-speed circuits. The locked revs should help motors last longer, while cutting traction control puts full power management back in the rider's right hand.
Will ditching electronic safety nets make the V-twin battles even wilder? We will see how teams handle the new setup once 2027 arrives.
