For the youngest shredders

KTM 50 SX Mini, as the name suggests, is for the youngest shredders who want to take to the tracks from a young age. Built for 4 to 10-year-olds, this bike is the perfect addition to any family. But this small size doesn’t mean it is small in features too because this bike uses pretty much the same technology that powers the big bikes. The only difference is that it has smaller wheels and a lower seat size to suit these young children.

In addition, it has a child-friendly power delivery, so the young ones can control it all by themselves, without needing much help from the adults. In fact, this bike is one of the first choices that many parents make when they want to introduce their child to the world of dirt bike racing. 

Overall, it has been built with these young children in mind, so it comes with an engine that delivers steady and optimal power that can be handled by the children. Plus, it comes with an automatic clutch, high-quality WP XACT shock absorbers on the front and rear side, and graphics that are sure to look cool and appealing.
