Overview

Introducing the 2005 KTM 450 MXC USA, a robust contender in the cross-motocross arena that has captivated riders with its blend of power, agility, and ruggedness. Designed specifically for the demanding terrains of the United States, this machine embodies KTM's commitment to performance and innovation. With a purpose-built chassis and a potent engine, the 450 MXC USA is aimed at both serious competitors and recreational riders who crave the thrill of off-road adventures. Its vibrant orange frame and distinctive styling not only make it a head-turner on the track but also a symbol of KTM's racing pedigree. At the heart of the 450 MXC USA is a single-cylinder, four-stroke engine that displaces 447.90 cc, delivering exhilarating power and torque for any off-road challenge. With an impressive compression ratio of 11.0:1 and a precise Keihin MX FCR 39 carburettor, this motorcycle offers responsive throttle control and a thrilling acceleration that keeps riders engaged. The liquid-cooled engine is coupled with a 6-speed transmission, allowing for smooth gear changes and optimal performance across various terrains. The bike’s lightweight design, at just 112.2 kg (247.4 lbs), further enhances its agility, making it a nimble partner on tight trails and rocky climbs. Riders will appreciate the balanced handling and confidence-inspiring stability provided by the WP-USD 48 mm front suspension and WP-PDS shock absorber at the rear, designed to absorb impacts and deliver a comfortable ride. The 2005 KTM 450 MXC USA is packed with advanced features that elevate the riding experience. Its chromium molybdenum frame not only contributes to the bike's strength and durability but also ensures a precise feel when navigating challenging courses. The dual-disc brake system—featuring a 216 mm front disc and a 260 mm rear disc—provides reliable stopping power, instilling confidence even in the most technical sections. Plus, the convenience of both electric and kick starters means that starting the bike is hassle-free, whether in the pit or on the trail. With a fuel capacity of 13 liters, riders can tackle longer rides without frequent stops, allowing for uninterrupted exploration of off-road landscapes. **
