2019 Yamaha XTZ 125 Technical Analysis & Specification Breakdown

Engineered by Yamaha for the enduro - offroad motorcycle segment, the 2019 Yamaha XTZ 125 utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.5 HP (9.1 kW) at 8,000 rpm while maximum torque reaches 11.6 Nm (8.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 100.8 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 rpm), 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 XTZ 125 measures 118 kg (260 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.44 kg per horsepower). Rider ergonomics and chassis geometry center around a 840 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
