Built around Yamaha's naked motorcycle platform, the 2025 Yamaha MT-09 Y-AMT utilizes a 890 cc (54.3 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 119 HP (86.9 kW) at 10,000 rpm while maximum torque reaches 93 Nm (68.6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 133.7 HP per liter and a 3,000 rpm working window between peak torque (7,000 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 Y-AMT measures 196 kg (432 lbs) wet (curb), translating to a power-to-weight ratio of 0.61 HP/kg (1.65 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,430 mm (56.3 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 L/100 km provides an estimated theoretical range of roughly 280 km (174 miles) between fill-ups.
