MXA VIDEO: FIRST RIDE ON THE 2021 KTM 125SX TWO-STROKE
This is the state of the art 125cc, two-stroke, race bike. It weighs 194 pounds (compared to the YZ125’s 200 pounds), makes 37.52 horsepower (compared to the YZ125’s 33.99 horsepower). It is a blast to ride because it feels torquey (thanks to 17.69 pound-feet of torque compared to the YZ125’s 16.01 pound-feet). This is great bike that unfortunately was build after the glory days of 125 two-stroke Nationals and Supercross events. That doesn’t mean that you can’t enjoy it and run the 250 four-strokes ragged.
