2008 Yamaha YBR125 Technical Analysis & Specification Breakdown

At the heart of the 2008 Yamaha YBR125 allround motorcycle, Yamaha utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.1 HP (7.3 kW) at 10,000 rpm while maximum torque reaches 9.6 Nm (7.1 lb-ft) at 2,100 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 81.5 HP per liter and a 7,900 rpm working window between peak torque (2,100 rpm) and peak power (10,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the YBR125 measures 113 kg (249 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.19 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
