Built around Honda's scooter motorcycle platform, the 2008 Honda Metropolitan pairs a 49 cc (3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 39.0 x 46.0 mm (1.5 x 1.8 inches) with a 10.5:1 compression ratio.
On the scales, the Metropolitan measures 79.8 kg (176 lbs) dry. Rider ergonomics and chassis geometry center around a 719 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,191 mm (46.9 in) wheelbase engineered for quick, flickable steering geometry. The 4.99-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
