KTM 450 SX-F 2014: POWER FOR ALL

With the 450 SX‑F, KTM has a winning motorcycle in its range, which derives its potential from a high-capacity engine and a chassis perfectly tuned to the power unit. Ryan Dungey won the 2012 title in the AMA MX1 class with this machine and he saw no reason whatsoever to change bikes for his title defence. No wonder; the compact SOHC engine guarantees brutal yet controllable power with its revolutionary injection technology. Above all, the 450 SX‑F scores highly compared with other large four-strokes in terms of performance and handling. It's the right choice for every motocross rider in the MX1 class for whom torque and performance combined with controllable rideability are pivotal.
