Positioned in Yamaha's naked motorcycle lineup, the 2015 Yamaha FZ-09 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 10,120 rpm while maximum torque reaches 61.5 Nm (45.3 lb-ft) at 8,480 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 1,640 rpm working window between peak torque (8,480 rpm) and peak power (10,120 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 FZ-09 measures 187.8 kg (414 lbs) wet (curb), translating to a power-to-weight ratio of 0.61 HP/kg (1.63 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 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 5.35 L/100 km provides an estimated theoretical range of roughly 262 km (163 miles) between fill-ups.
