Technical Overview
1997 Yamaha FZ 400 Fazer Technical Analysis & Specification Breakdown
Engineered by Yamaha for the naked motorcycle segment, the 1997 Yamaha FZ 400 Fazer relies on a 399 cc (24.4 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 53 HP (38.7 kW) at 9,500 rpm while maximum torque reaches 38 Nm (28 lb-ft) at 9,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 132.8 HP per liter, 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 400 Fazer measures 199 kg (439 lbs) wet (curb), translating to a power-to-weight ratio of 0.27 HP/kg (3.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 2.86 L/100 km provides an estimated theoretical range of roughly 629 km (391 miles) between fill-ups, while factory top speed is listed at 180 km/h (112 mph).
