KTM 450 EXC Racing
Key specifications
Overview
The 2005 KTM 450 EXC Racing motorcycle stands as a hallmark of precision engineering in the cross-motocross segment, designed for the discerning off-road enthusiast who demands performance, agility, and durability. Blending the raw power of a racing machine with the ruggedness needed for tough terrains, the 450 EXC is a favorite among competitive riders and weekend warriors alike. Its lightweight construction combined with cutting-edge technology positions this bike as a formidable contender on any track or trail, appealing to those who seek both competitive edge and adventure in their riding experience. At the heart of the KTM 450 EXC is a robust single-cylinder, four-stroke engine with a displacement of 447.92cc. This powerhouse delivers an impressive torque band and acceleration, thanks to its high compression ratio of 11.0:1, and a finely-tuned Keihin MX FCR 39 carburetor that optimizes fuel delivery for peak performance. Riders will appreciate the smooth power delivery throughout the 6-speed gearbox, allowing for seamless transitions between gears, whether conquering steep inclines or powering through the straights. With a wet multi-disc hydraulic clutch, control is precise and responsive, giving riders confidence in demanding situations. The bike's lightweight frame, clocking in at a mere 113.5 kg (250.2 pounds), ensures that it remains agile and easy to maneuver, making it a pleasure to ride in technical sections. KTM has outfitted the 450 EXC with features that enhance both its performance and rider experience. The frame, constructed from chromium molybdenum, offers exceptional strength without compromising weight. The WP-USD 48mm front forks and WP-PDS rear shock absorber provide excellent suspension travel, allowing the bike to absorb bumps and maintain stability over rugged terrain. Add to this an electric starter for convenience and a kickstarter as a backup, and you have a machine that is equipped for any challenge. The bike’s 8-liter fuel capacity ensures extended rides without frequent refueling, while its generous ground clearance of 380mm allows for confident navigation over obstacles. **
