The whip cracking KTM 125 SX has been at the front for years. With phenomenal performance on tap, it will be there for many more seasons to come. A compact chassis and the lowest weight out there is teamed up with a high performance 125cc 2-stroke engine for a surefire trophy collection. Get shredding, youngsters.
The engine of the 125 SX has been known to be the most powerful and most competitive engine of its class and it is clear two-strokes are going to have a successful future at KTM thanks to outstanding power-to-weight ratio, a low operating cost and simplicity. The 2018 KTM 125 SX produces better power all over the rev range while being more compact and significantly lighter than all others. Improvements such as aluminum head stays, redesigned radiator guards and new suspension damping settings further elevate the READY TO RACE game of the 125 SX.
