In a sport where perfection is elusive, the KTM 350 SX-F continues to set high standards in motocross performance. Known for its lightweight design and agility, the latest iteration of the 350 SX-F has integrated enhanced horsepower, prompting riders to describe it as “perfect” — a term seldom used in competitive racing environments.
Engine Performance and Modifications
Master engine tuner Jamie Ellis of Twisted Development has played a pivotal role in unlocking the KTM’s potential. Renowned in the paddock for his modifications, Ellis has a track record of success, including powering Ken Roczen to a red plate. Key modifications for the 350 SX-F include:

- Re-Valve Shock with Bladder Kit: Ensures stability and comfort during high-speed maneuvers.
This meticulous tuning, along with the implementation of a TD Spec 4.1 Race Muffler System, results in a well-rounded package that maximizes speed while maintaining control.
Additional Upgrades
With an eye toward rider comfort and performance, the KTM 350 SX-F also features:
- Champ Bend Bars and Lock-On Grips: Enhance grip and control.
- Custom “Boys Night Out” Graphics: Add a personal touch to the aesthetics.
- MX34 Front and Rear Tires at 12.5 PSI: Ensuring optimal traction and durability on the track.
