At the heart of the 2017 Yamaha MT-09 Tracer sport motorcycle, Yamaha 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 8,900 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 1,100 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 Tracer measures 210 kg (463 lbs) wet (curb), translating to a power-to-weight ratio of 0.55 HP/kg (1.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
