Built around KTM's super motard motorcycle platform, the 2011 KTM 450 SMR pairs a 449.3 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 97.0 x 60.8 mm (3.8 x 2.4 inches) with a 12.5:1 compression ratio.
On the scales, the 450 SMR measures 111.5 kg (246 lbs) dry. Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 8.2-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
