At the heart of the 2005 KTM 450 SMR super motard motorcycle, KTM features a 449.4 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, maximum torque reaches 42.5 Nm (31.3 lb-ft) at 3,250 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 SMR measures 108.5 kg (239 lbs) dry. Rider ergonomics and chassis geometry center around a 855 mm (33.7 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.
