Engineered by Yamaha for the naked motorcycle segment, the 2005 Yamaha FZ1 relies on a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 146.8 HP (107.2 kW) while maximum torque reaches 106 Nm (78.2 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 147.1 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the FZ1 measures 221 kg (487 lbs) wet (curb), translating to a power-to-weight ratio of 0.66 HP/kg (1.51 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,450 mm (57.1 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, while factory top speed is listed at 246 km/h (153 mph).
Within MotoLibrary's Yamaha archive, this model family spans 13 indexed model years from 2005 to 2017, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
