Vehicle Information
KTM 450 XC Dirt Bike (2006-2007)
The KTM 450 XC from 2006 and 2007 is a high-performance off-road motorcycle designed for cross-country riding. These models featured a 447.92 cc single-cylinder, 4-stroke, SOHC engine in 2006, increasing to 449.4 cc in 2007. Known for its robustness and power, the 450 XC offered a dynamic riding experience, notably with its six-speed transmission and electric start. The 2007 model year introduced significant updates. The transmission evolved to a semi-close-ratio version for the 450 XC, and a new 450 XC-W model with a wide-ratio transmission was introduced. Suspension components were updated with new fork internals for improved stiffness, and the chassis received reinforcement. Black rims became standard, and brake discs were redesigned. The RFS (Racing Four Stroke) engine, known for its torque, saw its final year of production in 2007 for these models, benefiting from refinements based on racing development.
