We are getting tired of having to stick up for the 350cc power plant just because most professional racers don't race one, so we are just going to be blunt here. A majority of casual to even serious moto riders don’t need and can’t use all of the brute force of a modern 450. And yes, the KTM 350 SX-F really does have the the positive characteristics of both the 250 and 450 SX-Fs. If you are in the market for a new bike to ride at you favorite tracks, give a 350 a good hard look. For 2017 KTM gave the same changes to all of the SX-F bikes and they are: WP AER 48 fork, aluminum upper engine mounts, softer rear spring, traction control, stiffer top triple clamp, 10mm longer brake pedal, and new handlebar clamps.
