Built around Kawasaki's custom - cruiser motorcycle platform, the 2005 Kawasaki Vulcan 800 pairs a 805 cc (49.1 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 88.0 x 66.2 mm (3.5 x 2.6 inches) with a 9.5:1 compression ratio.
On the scales, the Vulcan 800 measures 225 kg (496 lbs) dry. Rider ergonomics and chassis geometry center around a 711 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,626 mm (64 in) wheelbase engineered for planted straight-line stability. The 15.14-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
