At the heart of the 2017 Suzuki QuadSport Z400 atv motorcycle, Suzuki relies on a 398 cc (24.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 90.0 x 62.6 mm (3.5 x 2.5 inches) with a 11.3:1 compression ratio.
On the scales, the QuadSport Z400 measures 193 kg (425 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,245 mm (49 in) wheelbase engineered for quick, flickable steering geometry. The 9.1-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
