Vehicle Information
KTM 250 XC Dirt Bike (2006-2026)
The KTM 250 XC, an iconic two-stroke off-road motorcycle, has undergone significant evolutions between 2006 and 2026. This model is renowned for its robust performance and versatility in cross-country riding. Throughout this period, it has maintained a 249cc liquid-cooled, single-cylinder, two-stroke engine, but has benefited from major updates in fuel delivery and chassis design. Initially carbureted (2006-2017), the 250 XC saw its chassis and engine reworked multiple times, notably in 2010, 2011, 2013, and 2017, with the introduction of a new frame and improved engine architecture. From 2020, it adopted Transfer Port Injection (TPI), followed by Electronic Fuel Injection (EFI) in 2023, offering more precise throttle response and better engine management. These changes refined power delivery and reduced vibrations, while maintaining its sporty character. Q : How can I ensure parts fit my KTM 250 XC?
