2010 Husqvarna SM 125S Technical Analysis & Specification Breakdown
Positioned in Husqvarna's super motard motorcycle lineup, the 2010 Husqvarna SM 125S features a 124.8 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 15 HP (10.9 kW) at 9,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120.2 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the SM 125S measures 113.5 kg (250 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.57 kg per horsepower). 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 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
