Overview

Introducing the 2005 KTM 400 EXC Racing motorcycle—an embodiment of performance and precision designed for the rugged terrains of cross-motocross racing. KTM has long been known for its commitment to producing top-tier off-road motorcycles, and the 400 EXC Racing is no exception. With its powerful single-cylinder engine, lightweight chassis, and advanced suspension technology, this bike caters to both the competitive racer and the passionate trail rider, making it a standout option in the off-road segment. At the heart of the 400 EXC Racing lies a robust 398.20 cc four-stroke engine that delivers an exhilarating combination of power and torque. With a compression ratio of 11.0:1 and a sophisticated Keihin MX FCR 39 carburetor, this motorcycle provides an immediate throttle response that is perfect for tackling steep inclines or tight corners. The six-speed gearbox allows riders to seamlessly navigate various terrains, while the liquid cooling system ensures optimal engine performance even during extended rides. Weighing in at just 113.5 kg (250.2 pounds), the bike's lightweight design further enhances its agility, allowing riders to experience nimble handling and confident cornering. KTM has equipped the 400 EXC Racing with cutting-edge features that elevate the riding experience. The chromium-molybdenum frame provides exceptional strength while keeping the overall weight down, enhancing the bike's durability on demanding trails. The WP-USD 48 mm front suspension and WP-PDS rear shock absorber offer superior handling and 335 mm of rear travel, absorbing bumps and ensuring a smooth ride over rough terrain. Additionally, the dual braking system, featuring a 216 mm front disc and a 260 mm rear disc, delivers precise stopping power, giving riders the confidence to push their limits. For added convenience, both electric and kick starters are available, ensuring you can get back on the trail swiftly when needed. **

Pros
