Positioned in Yamaha's scooter motorcycle lineup, the 2007 Yamaha C3 relies on a 49 cc (3 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 38.0 x 43.5 mm (1.5 x 1.7 inches) with a 12.0:1 compression ratio.
On the scales, the C3 measures 84.8 kg (187 lbs) dry. Rider ergonomics and chassis geometry center around a 737 mm (29 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.54-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
