VIDEO: 2017 KTM 250 SX First Impression

June first marked the start of new bike season with KTM’s 2017 250 SX intro. The exciting news is that KTM is still investing in and developing its two-strokes, and this premiere class motocross bike is all new from the ground up, including a brand new engine with a new powervalve system and an emphasis on reducing vibration – a clear shot at the four-strokes on the track. We put in some laps and shot some video, and here are our first impressions of the bike.
