2004 Husqvarna SM 125 S Technical Analysis & Specification Breakdown
At the heart of the 2004 Husqvarna SM 125 S super motard motorcycle, Husqvarna 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 54.0 x 54.5 mm (2.1 x 2.1 inches) with a 8.8:1 compression ratio.
On the scales, the SM 125 S measures 113.5 kg (250 lbs) dry. Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,470 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 10.5-liter (2.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
