Built around Yamaha's sport touring motorcycle platform, the 2002 Yamaha XJ 900 S Diversion features a 892 cc (54.4 cu in) air-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 89.5 HP (65.3 kW) at 8,250 rpm while maximum torque reaches 83.3 Nm (61.4 lb-ft) at 7,000 rpm. With a specific output of 100.3 HP per liter and a 1,250 rpm working window between peak torque (7,000 rpm) and peak power (8,250 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 S Diversion measures 239 kg (527 lbs) dry, translating to a power-to-weight ratio of 0.37 HP/kg (2.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,505 mm (59.3 in) wheelbase engineered for balanced agility and highway composure.
