2003 Husqvarna SM 125 S Technical Analysis & Specification Breakdown
Engineered by Husqvarna for the super motard motorcycle segment, the 2003 Husqvarna SM 125 S relies on a 124.8 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 53.3 x 53.3 mm (2.1 x 2.1 inches) with a 8.8:1 compression ratio.
On the scales, the SM 125 S measures 112 kg (247 lbs) dry. Rider ergonomics and chassis geometry center around a 872 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,479 mm (58.2 in) wheelbase engineered for balanced agility and highway composure. The 11.2-liter (3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
