Engineered by Honda for the enduro - offroad motorcycle segment, the 2009 Honda CRF50F relies on a 49 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches) with a 10.0:1 compression ratio.
On the scales, the CRF50F measures 49.9 kg (110 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 549 mm (21.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 914 mm (36 in) wheelbase engineered for quick, flickable steering geometry. The 2.64-liter (0.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
