Michael Inderbitzin
Michael Inderbitzin announced his arrival as a Progressive American Flat Track race winner alongside the introduction of the AFT Production Twins class in 2018. The Modesto, California, rider not only swept the two races in the category’s limited ‘18 introduction, he did so in dramatic fashion both times out.
Inderbitzin chased down and blitzed the entire pack at the Springfield Mile I to claim the first-ever Production Twins checkered flag, and then pulled off another unlikely come-from-behind win when the series returned to the venue for the Springfield Mile II.
Inderbitzin built on that uptick in success in 2019, adding another AFT Production Twins top-five finish while scooping up his first-career AFT Singles podium with a runner-up result at the Perris Half-Mile.
He took another step forward in 2020, enjoying arguably his finest season as a professional. Inderbitzin earned top fives in both AFT Singles and AFT Production Twins action, the highlight being a AFT Singles runner-up in Dallas.
Inderbitzen followed that up with a six top-ten AFT Singles campaign in 2021, highlighted by a top five at the Chicago Half-Mile. He then added three more top tens in 2022, including top-five at the Texas Half-Mile.
He returned following a year away from the scene in 2023, earning three points-paying finishes in AFT Singles competition, including an eighth-place run at the Silver Dollar Short Track.
Inderbitzen stepped up to take on the best in the business in 2025, competing in the Mission AFT SuperTwins category for the first time, securing points-paying finishes on three occasions.
