Positioned in Honda's sport motorcycle lineup, the 2020 Honda CB125E relies on a 124.1 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 56.5 x 49.5 mm (2.2 x 1.9 inches) with a 9.0:1 compression ratio.
On the scales, the CB125E measures 137 kg (302 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 767 mm (30.2 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,286 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
