FZS FI

2017 Yamaha FZS FI Technical Analysis & Specification Breakdown

Built around Yamaha's naked motorcycle platform, the 2017 Yamaha FZS FI utilizes a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 13.2 HP (9.6 kW) at 8,000 rpm while maximum torque reaches 12.8 Nm (9.4 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 88.6 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 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 FI measures 132 kg (291 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (10 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 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
