Supermotard 125
2003 Siamoto Supermotard 125 Technical Analysis & Specification Breakdown
Positioned in Siamoto's super motard motorcycle lineup, the 2003 Siamoto Supermotard 125 relies on a 124 cc (7.6 cu in) single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 13 HP (9.5 kW) at 8,000 rpm. With a specific output of 104.8 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 Supermotard 125 measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,460 mm (57.5 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
