Built around Yamaha's sport motorcycle platform, the 2021 Yamaha MT09TR GT utilizes a 847 cc (51.7 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 115 HP (83.9 kW) at 10,000 rpm while maximum torque reaches 87.5 Nm (64.5 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 135.8 HP per liter and a 1,500 rpm working window between peak torque (8,500 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 MT09TR GT measures 227 kg (500 lbs) wet (curb), translating to a power-to-weight ratio of 0.51 HP/kg (1.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,501 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.5 L/100 km provides an estimated theoretical range of roughly 327 km (203 miles) between fill-ups.
