ÖTSM
Austrian 4-Stroke Team Kart Championship
Austria’s team championship for 4-stroke karts: endurance racing on Saturday, sprints on Sunday – in 2026 over five race weekends in Austria, the Czech Republic and Slovakia. Right in the mix: the motorSPORTaktiv teams.
What is the ÖTSM?
The ÖTSM is the Austrian 4-Stroke Team Kart Championship, organised by the Austrian Kart Sport Association (Österreichische Kart Sport Vereinigung).
Teams race 4-stroke race karts. Every race weekend combines two disciplines: on Saturday the 6-hour endurance race is all about teamwork, driver changes and strategy; on Sunday short sprint races are all about pure speed.
It’s not only the team that is scored: there are also separate classifications, for example for the sprints and for juniors.
motorSPORTaktiv competes with three teams: motorSPORTaktiv.at, mSa keyman.at and mSa LASERTEC. The way into a team is our ÖTSM training in the series’ race karts.
