XJ 900 F

1994 Yamaha XJ 900 F Technical Analysis & Specification Breakdown

At the heart of the 1994 Yamaha XJ 900 F motorcycle, Yamaha pairs a 891 cc (54.4 cu in) in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 92 HP (67.2 kW) at 9,000 rpm while maximum torque reaches 75.5 Nm (55.7 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 103.3 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), 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 XJ 900 F measures 218 kg (481 lbs) dry, translating to a power-to-weight ratio of 0.42 HP/kg (2.37 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. The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
