At the heart of the 2010 Dafier STF 50 enduro - offroad motorcycle, Dafier utilizes a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 6.3 HP (4.6 kW), transferring power to the rear wheel through chain final drive. Internal engine geometry specifies a bore and stroke of 41.2 x 39.0 mm (1.6 x 1.5 inches) with a 7.0:1 compression ratio.
On the scales, the STF 50 measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 8.3-liter (2.2 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 415 km (258 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).

Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
