Engineered by Atlas Honda for the sport motorcycle segment, the 2020 Atlas Honda CB250F pairs a 249.6 cc (15.2 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 71.0 x 63.0 mm (2.8 x 2.5 inches) with a 11.0:1 compression ratio.
On the scales, the CB250F measures 135 kg (298 lbs) dry. Rider ergonomics and chassis geometry center around a 784 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,386 mm (54.6 in) wheelbase engineered for quick, flickable steering geometry. The 16.5-liter (4.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
