King of the Baggers 2027: rev limits and a control ECU
MotoAmerica caps Harley-Davidson at 7,000 rpm and Indian at 7,500, bans traction and lift control through a control ECU, and opens the class to other makers.

On 4 November MotoAmerica announced new technical rules for the Mission King Of The Baggers class. President Wayne Rainey said Harley-Davidson had decided to run in a spec exhibition series abroad, and not compete against the other manufacturers in America for a national championship. Indian Motorcycle is increasing its paddock presence, and the class is opening to other manufacturers.
Rev limits and a control ECU
Rev limits for 2027 are 7,000 rpm for Harley-Davidson and 7,500 rpm for Indian. The existing balancing framework between manufacturers stays in place. MotoAmerica says the changes aim for longer engine life and fewer rebuilds while keeping the racing close, and that it is working with several engine suppliers on access to competitive equipment.
Full-season competitors must use the MotoAmerica Maxx ECU Race unit with controlled firmware. The system prohibits traction control and lift control and collects the same data from every bike. Single-event entries and teams racing three rounds or fewer are exempt.
Other manufacturers can ask to enter production-based touring and bagger motorcycles, subject to technical and competitive evaluation. The final rules package and technical bulletins will be published before the 2027 season starts.
Seven rounds and a bigger purse
On 6 November MotoAmerica said the 2027 season has seven rounds and starts at the Daytona 200. The purse pays the top 12 in each race, with $3,000 for a win, and totals $300,020 for the season, which the series calls a 114% increase over 2026. With the Baggers Challenge and contingency money from Indian, Drag Specialties, Öhlins and Accossato Racing, up to $613,919 is available if every programme pays out in full.
