Vehicle Information
KTM 250 MXC Dirt Bike (1983-2005)
The KTM 250 MXC, produced from 1983 to 2005, was a two-stroke, liquid-cooled off-road motorcycle designed for cross-country racing. With a consistent 249cc engine displacement, it was engineered for broad, tractable power delivery, making it ideal for varied off-road conditions, distinguishing it from the peakier power of its motocross (SX) counterparts. The MXC designation itself signifies "Motocross Cross-Country," positioning it as KTM's dedicated platform for GNCC and regional XC formats. Over its 22-year production, the 250 MXC underwent numerous significant updates. Early models (1983-1989) introduced the water-cooled 250cc engine, a new frame, and Pro Lever single-shock suspension, with a notable engine change and kickstarter relocation around 1989-1990. The mid-period (1990-1999) saw a "completely new 250 enduro bike" in 1990, followed by improvements in clutch and brakes, and a transition to orange plastics and a new Kokusan ignition system by 1997. The later years (2000-2005) brought major engine redesigns in 2000 (new bore/stroke for improved power and cooling) and 2002 (new 48mm WP-USD forks, WP shocks, swingarm, and internal engine enhancements), significantly evolving the platform. Q: How do I ensure I select the correct parts for my KTM 250 MXC?
A: Due to the numerous updates and generational changes between 1983 and 2005, it is crucial to select your specific model year using our year/edition selector to guarantee fitment.
