Overview

Introducing the 2007 KTM 250 SX-F, a powerhouse in the world of cross-motocross motorcycles that captures the essence of competitive racing. Renowned for its agility and lightweight frame, this bike is designed for serious riders who crave performance on the track. With its powerful four-stroke engine and cutting-edge suspension technology, the 250 SX-F has established itself as a top contender in the motocross category, appealing to both amateur racers and seasoned professionals alike. At the heart of the KTM 250 SX-F lies a potent 249.5cc single-cylinder engine that delivers thrilling acceleration and impressive torque. With a compression ratio of 12.8:1 and a sophisticated Keihin MX FCR 39 carburettor fueling the fire, this engine is engineered for responsiveness and power delivery. Riders will appreciate the 6-speed gearbox that allows for seamless shifting, whether navigating tight corners or blasting down straights. The liquid cooling system ensures optimal performance even in the heat of competition, while the hydraulic wet multi-disc clutch affords precise control, making this bike a joy to ride on challenging terrains. The 250 SX-F features a robust central double-cradle frame crafted from 25CrMo4 steel, which enhances its durability while keeping weight to a minimum. With a total weight of just 98.5 kg (217.2 pounds), it’s incredibly nimble, making it easy to maneuver through technical sections of the track. The WP USD front suspension and monoshock PDS rear suspension provide a plush yet responsive ride, with 115 mm of front travel and an impressive 185 mm at the rear. Adding to its competitive edge, the bike boasts a ground clearance of 380 mm (15 inches) and a seat height of 925 mm (36.4 inches), allowing riders to navigate obstacles with confidence. **

Pros

  • Lightweight and Agile: At 98.5 kg, the 250 SX-F is easy to handle, allowing for quick changes in direction and improved cornering.
  • Powerful Engine Performance: The single-cylinder, four-stroke engine delivers robust power and rapid acceleration, ideal for competitive racing.
  • Advanced Suspension Technology: The WP suspension system ensures superior handling and comfort, absorbing bumps and providing excellent traction.
