Built around Suzuki's atv motorcycle platform, the 2016 Suzuki KingQuad 400ASi pairs a 376 cc (22.9 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 82.0 x 71.2 mm (3.2 x 2.8 inches) with a 9.0:1 compression ratio.
On the scales, the KingQuad 400ASi measures 285 kg (628 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
