2009 Yamaha Black X-Max 125 Technical Analysis & Specification Breakdown

Positioned in Yamaha's scooter motorcycle lineup, the 2009 Yamaha Black X-Max 125 relies on a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 13.9 HP (10.1 kW) at 8,750 rpm while maximum torque reaches 11.3 Nm (8.4 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 111.5 HP per liter and a 2,250 rpm working window between peak torque (6,500 rpm) and peak power (8,750 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 Black X-Max 125 measures 166 kg (366 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (11.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,525 mm (60 in) wheelbase engineered for planted straight-line stability. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
