Introducing the 2011 KTM 250 SX-F, a standout in the competitive world of enduro and off-road racing. Renowned for its exceptional agility and power-to-weight ratio, this bike is designed to dominate both challenging trails and motocross tracks alike. KTM has long been celebrated for pushing the boundaries of performance, and the 250 SX-F is no exception, embodying the perfect blend of cutting-edge technology and robust engineering that appeals to both seasoned riders and newcomers alike. At the heart of the KTM 250 SX-F lies a potent 248.60 ccm single-cylinder, four-stroke engine that delivers exhilarating performance. With a compression ratio of 13.2:1, this powerplant boasts a responsive throttle and remarkable torque across the rev range. The 76.0 x 54.8 mm bore and stroke configuration, combined with a 6-speed gearbox and a hydraulic-operated wet double disk clutch, creates seamless power delivery and allows riders to tackle steep inclines and tight turns with confidence.

KTM has equipped the 250 SX-F with an impressive array of features that elevate its performance. The bike's central double-cradle frame, crafted from 25CrMo4 steel, provides unparalleled rigidity while keeping weight to a minimum. The WP USD 48 mm front forks and WP-Monoshock rear suspension, both offering 185 mm of travel, soak up bumps and ensure a comfortable ride over rough terrain. The braking system, comprising a 260 mm front and a 220 mm rear disc, delivers powerful stopping power, instilling confidence in every rider. Plus, with a fuel capacity of 7.5 liters, the 250 SX-F is ready for extended adventures without frequent stops. **
