Positioned in Kawasaki's custom - cruiser motorcycle lineup, the 2019 Kawasaki Vulcan S ABS Cafe pairs a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 48 HP (35 kW) at 5,700 rpm while maximum torque reaches 62.8 Nm (46.3 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 74 HP per liter, 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 ABS Cafe measures 228 kg (503 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 706 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 supports practical everyday commuting and weekend road stints.
