2019 Yamaha MT-09 Technical Analysis & Specification Breakdown

At the heart of the 2019 Yamaha MT-09 naked motorcycle, Yamaha features a 847 cc (51.7 cu in) liquid-cooled in-line three, four-stroke configuration. In factory specification, peak output is rated at 113.5 HP (82.8 kW) at 10,000 rpm while maximum torque reaches 87.5 Nm (64.5 lb-ft) at 8,900 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 134 HP per liter and a 1,100 rpm working window between peak torque (8,900 rpm) and peak power (10,000 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 MT-09 measures 193 kg (425 lbs) wet (curb), translating to a power-to-weight ratio of 0.59 HP/kg (1.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 5.5 L/100 km provides an estimated theoretical range of roughly 255 km (158 miles) between fill-ups.
