2018 KTM 50SX MINI

Built for the smallest of racers, the 50 SX Mini incorporates much of the technology of the 50 SX with a more friendly power delivery, smaller wheels and a lower seat height. It is a genuine dirt bike that, like its bigger siblings, is produced with top-quality components. This makes the 50 SX Mini the best choice for a young rider’s first KTM. The 2-stroke engine delivers steady, controllable power, incorporating an automatic clutch that allows the rider to concentrate on the terrain, not shifting. Just like the entire READY TO RACE KTM product line, the 50 SX Mini has slim bodywork for the best possible ergonomics, looking just like the biggest and baddest 450 SX-F.
