Engineered by Husqvarna for the minibike, sport motorcycle segment, the 2012 Husqvarna SM50 pairs a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 39.5 x 40.0 mm (1.6 x 1.6 inches) with a 7.1:1 compression ratio.
On the scales, the SM50 measures 43.4 kg (96 lbs) dry. Rider ergonomics and chassis geometry center around a 680 mm (26.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 995 mm (39.2 in) wheelbase engineered for quick, flickable steering geometry. The 2.7-liter (0.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
