1998 Yamaha XJ 600 S Diversion Technical Analysis & Specification Breakdown

Built around Yamaha's sport touring motorcycle platform, the 1998 Yamaha XJ 600 S Diversion utilizes a 599 cc (36.6 cu in) air-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 61 HP (44.5 kW) at 8,500 rpm while maximum torque reaches 53 Nm (39.1 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 101.8 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 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 600 S Diversion measures 187 kg (412 lbs) dry, translating to a power-to-weight ratio of 0.33 HP/kg (3.07 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
