Technical Overview
2000 Yamaha WR 400 F Technical Analysis & Specification Breakdown
At the heart of the 2000 Yamaha WR 400 F enduro - offroad motorcycle, Yamaha relies on a 399 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 45 HP (32.8 kW) at 9,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 112.8 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 WR 400 F measures 114 kg (251 lbs) dry, translating to a power-to-weight ratio of 0.39 HP/kg (2.53 kg per horsepower). Rider ergonomics and chassis geometry center around a 991 mm (39 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
