Engineered by Honda for the naked motorcycle segment, the 2020 Honda CB300R features a 286 cc (17.5 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 76.0 x 63.0 mm (3.0 x 2.5 inches) with a 10.7:1 compression ratio.
On the scales, the CB300R measures 143.8 kg (317 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,354 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 10.22-liter (2.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
