Technical Overview
2004 KTM 450 SMC USA Technical Analysis & Specification Breakdown
Built around KTM's super motard motorcycle platform, the 2004 KTM 450 SMC USA relies on a 449.4 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 55 Nm (40.6 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 95.0 x 63.4 mm (3.7 x 2.5 inches) with a 12.0:1 compression ratio.
On the scales, the 450 SMC USA measures 106.3 kg (234 lbs) dry. Rider ergonomics and chassis geometry center around a 914 mm (36 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,481 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
