MXA VIDEO: WE TEST THE 2025 KTM 150SX TWO-STROKE

For the last two years, the 150SX two-stroke has been missing from KTM’s lineup, but now it’s back! Ever since KTM came out with their all-new fuel-injected two-stroke platform in 2023, the 150SX has been missing off the list. Now it’s back, and it comes with the new generation 2025 KTM chromoly steel frame, it has the updated linkage and the mapping has been tailored specifically for this bike. In this video, MXA’s Josh Mosiman has test riders Jake Alvarez and Tristun Alvarez ride the 2025 KTM 150SX and the 2024 KTM 125SX back-to-back at Perris Raceway.
