With KTM’s reputation for quality and engineering excellence, the 450 SX-F perfectly blends lightness and power, making it a formidable contender in any motocross or trail scenario. Whether you're tackling rugged trails or competing in races, this motorcycle stands ready to deliver an exhilarating ride. At the heart of the KTM 450 SX-F is its robust 449.30 ccm single-cylinder, four-stroke engine. With a high compression ratio of 12.5:1 and a bore and stroke of 97.0 x 60.8 mm, this powerhouse generates impressive torque and horsepower, providing riders with quick throttle response and exhilarating acceleration. The liquid-cooled engine is fed by a Keihin MX FCR 41 carburettor and is managed by a Kokusan digital DC-CDI ignition system, ensuring reliable performance in diverse conditions. Paired with a 4-speed gearbox and a hydraulic wet multi-disc clutch, the bike offers smooth gear transitions and responsive handling, allowing riders to navigate both technical trails and open tracks with confidence and agility. The 2008 KTM 450 SX-F is equipped with a cutting-edge chassis and suspension system that enhances its off-road capabilities. The central double-cradle frame, crafted from durable 25 CrMo4 steel, provides exceptional stability and strength, while the WP USD front suspension (with 300 mm of travel) and WP monoshock PDS rear suspension (featuring 335 mm of travel) effectively absorb bumps and obstacles, ensuring a comfortable ride over rough terrain. The braking system, equipped with single discs measuring 260 mm in the front and 220 mm in the rear, delivers reliable stopping power, allowing for precise control and safety. With a seat height of 960 mm, this bike is designed for maneuverability, catering to riders who demand agility and performance on the trail. **
