Positioned in Yamaha's custom - cruiser motorcycle lineup, the 1986 Yamaha XJ700XS utilizes a 697.3 cc (42.6 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 86 HP (62.8 kW) at 9,500 rpm while maximum torque reaches 67.7 Nm (49.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 123.3 HP per liter and a 1,500 rpm working window between peak torque (8,000 rpm) and peak power (9,500 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 XJ700XS measures 232 kg (511 lbs) wet (curb), translating to a power-to-weight ratio of 0.37 HP/kg (2.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,520 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 5.7 L/100 km provides an estimated theoretical range of roughly 228 km (142 miles) between fill-ups.
