Racer X Films: 2019 KTM 300XC Build

  • Racer X Films: 2019 KTM 300XC Build

Photos/Video: Simon Cudby
Text: David Pingree
Build: Jay Clark

The goal of this project was to take the best trail bike out there and make it even better. The 2017-18 KTM 300XC is fast becoming the dream bike for most die-hard trail riders. The 2019 kept the fully updated engine with counter balancer that cuts vibration to nothing and it also got the updated chassis/plastic used on the SXF models.   

Jay Clark kept the modifications to the engine and suspension simple and concentrated on making the bike more durable in tough trail conditions. The performance is smile-inducing once you hit the dirt. The 300cc two-stroke is an excellent engine size; not too big to be unmanageable and not so small you feel like you need more. Plus, the Lectron carb eliminates the need to change jetting as you go up or down in elevation or temperature. This bike goes from great to amazing in this project.
