At the heart of the 2012 Husqvarna SMS125 super motard motorcycle, Husqvarna pairs a 124.8 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 54.0 x 54.2 mm (2.1 x 2.1 inches) with a 8.8:1 compression ratio.
On the scales, the SMS125 measures 111 kg (245 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 929 mm (36.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,462 mm (57.6 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
