Overview

Introducing the 2008 KTM 250 SX, a formidable contender in the enduro-offroad segment that perfectly balances lightweight agility with robust performance. This motorcycle is designed for riders who crave the thrill of tackling challenging terrains and mastering tight trails. With its rich heritage in off-road racing, KTM has crafted the 250 SX to not only endure the rigors of competition but to thrive in them. This model is ideal for both seasoned riders and those looking to elevate their off-road experience, making it a popular choice among enthusiasts seeking a blend of performance and reliability. At the heart of the KTM 250 SX lies a potent 249cc single-cylinder, two-stroke engine, renowned for its quick revving capability and impressive power delivery. With a bore and stroke of 66.4 x 72.0 mm, this engine is expertly tuned to offer spirited acceleration and a thrilling ride. The Keihin PWK 36 S AG carburettor ensures optimal fuel delivery, while the Kokusan digital magneto CDI ignition system provides precise timing for maximum performance. Riders will appreciate the smooth shifting from the 5-speed gearbox, complemented by a hydraulically-operated wet multi-disc clutch that allows for seamless engagement and responsiveness. Whether you’re blasting through muddy trails or navigating rocky hills, the liquid-cooled engine and lightweight chassis provide the perfect combination for exceptional handling and control. The chassis of the KTM 250 SX is meticulously engineered with a central double-cradle-type frame made from durable 25CrMo4 steel, offering both strength and a low weight of just 95.4 kg (210.3 pounds). This bike features a cutting-edge WP suspension setup, including a 48mm WP USD fork in the front with an impressive 300 mm of travel, and a WP monoshock PDS in the rear with 335 mm of travel, ensuring that it absorbs the toughest bumps with ease. The braking system, featuring a 260 mm front disc and a 220 mm rear disc, provides reliable stopping power, while the 385 mm ground clearance and adjustable seat height of 960 mm enhance rider comfort and control over various terrains. The kick starter adds a classic touch, ensuring that the bike is always ready to roar back to life, even in the most remote locations. **
