FZS

2009 Yamaha FZS Technical Analysis & Specification Breakdown

Built around Yamaha's naked motorcycle platform, the 2009 Yamaha FZS relies on a 153 cc (9.3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 14 HP (10.2 kW) at 7,500 rpm while maximum torque reaches 14 Nm (10.3 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 91.5 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the FZS measures 137 kg (302 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (9.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,335 mm (52.6 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 560 km (348 miles) between fill-ups, while factory top speed is listed at 130 km/h (81 mph).
