Vehicle Information
KTM 380 MXC Dirt Bike (1998-2002)
The KTM 380 MXC, produced from 1998 to 2002, was a prominent two-stroke off-road motorcycle designed for cross-country riding. It shared its liquid-cooled, single-cylinder, 368 cc two-stroke engine and chassis with other KTM models like the EXC and SX. The engine, with a bore and stroke of 78 x 77 mm, featured a Twin Valve Control (TVC) exhaust system and a KTM Torque Chamber, known for delivering strong low-end and mid-range power. The 2002 380SX, which used the same engine, was rated at 55 horsepower. During its production, the 380 MXC underwent several refinements. The 380cc engine was introduced in 1998, replacing the earlier 360cc model. For the 2000 model year, KTM redesigned the engine cases, realigned the reed cage, and improved the braking system with a new front master cylinder, a smaller hydraulic line, a new rotor, and a larger piston in the rear master cylinder. Models from 2000 to 2002 also featured newer, lighter upside-down forks and a higher-output ignition system, with the 2002 model specifically equipped with WP Extreme forks. FAQ:
