Positioned in Dafier's super motard motorcycle lineup, the 2011 Dafier STM 125 features a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 9.5 HP (6.9 kW) at 8,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 76.2 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the STM 125 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.11 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 375 km (233 miles) between fill-ups, while factory top speed is listed at 108 km/h (67 mph).
