2023 MotoAmerica Supersport Championship

The 2023 MotoAmerica Supersport Championship season was the 9th season of the MotoAmerica Supersport class. The defending class champion was Josh Herrin, who vacated his title during 2023 to race in MotoAmerica Superbike.

Introduction of Extended Race Format
For the 2023 Supersport championship season, MotoAmerica piloted an extended race distance concept at the Barber Motorsports Park and Laguna Seca events. The extended races were double distance; therefore, worth double the points. The extended distance required the teams to make a pistop of minimum prescribed time to refuel the bike and make tire changes. Xavi Fores and the Warhorse HSBK Ducati team won both of the extended Supersport races during the 2023 season.

Josh Hayes Achieves Record AMA Career Wins
During the 2022 Supersport season, Josh Hayes tied Miguel Duhamel's record for all-time career wins in AMA Pro Road Racing by taking a double victory at New Jersey Motorsports Park. An unfortunate injury at Barber Motorsports Park during the final round of the 2022 season ended Hayes' attempt for the record that season, but Hayes returned for another season of Supersport competition with the SquidHunter Racing Team in 2023. On July 29th, 2023, Hayes took victory in Race 1 at Brainerd International Raceway to score his 87th career victory, taking sole possession of the record for career wins in AMA Pro Road Racing competition. Hayes added his 88th career win in the final race of the 2023 season at New Jersey Motorsports Park.
