Vehicle Information
KTM 450 SMS Dirt Bike (2004)
The 2004 KTM 450 SMS, also known as the 450 SMC or 450 S/MC Supermoto, is a supermoto category motorcycle renowned for its robust single-cylinder, four-stroke engine. It features the 449.4 cc RFS (Racing Four Stroke) engine, a platform used from 2000 to 2007, delivering approximately 54.38 horsepower. The main trims offered in 2004 included the 450 S/MC SUPERMOTO and 450 S/MR SUPERMOTO, sharing the same engine base as off-road models like the 450 SX and 450 EXC, but configured for supermoto riding. The 2004 model received significant improvements over 2003, including an updated rear subframe, airbox, rear fender, side panels, fuel tank, seat, and exhaust manifold. Specific 2004 refinements, shared with the 450 SX, included a new pipe tuned for added mid-range and high RPM power, more reliable clutch plates, a lighter ignition cover, adjusted exhaust port timing for smoother power delivery, and a crankshaft with increased rotating mass for better traction. The 2004 model was primarily kick-start. FAQ:
