Overview
Introducing the 2009 KTM 250 SX-F, a formidable contender in the enduro-offroad category that perfectly encapsulates KTM's racing heritage and commitment to performance. This lightweight powerhouse is designed for serious riders who crave agility and responsiveness on challenging terrains. With its striking orange and black color scheme, the 250 SX-F doesn’t just look the part—it embodies the spirit of competition that has propelled KTM to the forefront of off-road motorcycle racing. At the heart of the 250 SX-F lies a potent single-cylinder, four-stroke engine boasting a displacement of 248.60 ccm. With a compression ratio of 12.8:1, this engine delivers an exhilarating performance that keeps riders on the edge of their seats.

The central double-cradle-type frame made from robust 25CrMo4 steel, combined with an aluminum subframe, provides a perfect balance of strength and lightness, weighing in at just 98 kg (216.1 pounds). The WP USD front suspension with 48 mm forks offers a generous front travel of 300 mm, while the WP PDS shock absorber at the rear with 335 mm of travel ensures that riders can tackle rough terrain with confidence. Coupled with powerful braking systems—260 mm front and 220 mm rear discs—this motorcycle delivers exceptional stopping power, allowing riders to push their limits while maintaining control. **
