Vulcan S Tourer

2020 Kawasaki Vulcan S Tourer Technical Analysis & Specification Breakdown

Engineered by Kawasaki for the custom - cruiser motorcycle segment, the 2020 Kawasaki Vulcan S Tourer utilizes a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 60.4 HP (44.1 kW) at 7,500 rpm while maximum torque reaches 63 Nm (46.5 lb-ft) at 6,600 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 93.1 HP per liter and a 900 rpm working window between peak torque (6,600 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Vulcan S Tourer measures 228 kg (503 lbs) wet (curb), translating to a power-to-weight ratio of 0.26 HP/kg (3.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 705 mm (27.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,575 mm (62 in) wheelbase engineered for planted straight-line stability. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 4.4 L/100 km provides an estimated theoretical range of roughly 318 km (198 miles) between fill-ups.
