Engineered by Yamaha for the super motard motorcycle segment, the 2011 Yamaha DT50X pairs a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 2.8 HP (2.1 kW) while maximum torque reaches 3.3 Nm (2.4 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches) with a 12.0:1 compression ratio.
On the scales, the DT50X measures 104 kg (229 lbs) wet (curb). 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 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
