1999 Yamaha XJ 600 S Diversion Technical Analysis & Specification Breakdown

Engineered by Yamaha for the sport touring motorcycle segment, the 1999 Yamaha XJ 600 S Diversion relies on a 599 cc (36.6 cu in) air-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 61 HP (44.5 kW) at 7,500 rpm while maximum torque reaches 54 Nm (39.8 lb-ft), 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, 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 216 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.54 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 5.8 L/100 km provides an estimated theoretical range of roughly 293 km (182 miles) between fill-ups, while factory top speed is listed at 168 km/h (104 mph).
