Engineered by Suzuki for the atv motorcycle segment, the 2011 Suzuki QuadRacer R450 features a 450 cc (27.5 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 95.5 x 62.8 mm (3.8 x 2.5 inches) with a 11.7:1 compression ratio.
On the scales, the QuadRacer R450 measures 188 kg (414 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,285 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
