Built around Yamaha's scooter motorcycle platform, the 2008 Yamaha Zuma features a 49 cc (3 cu in) air-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 7.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.67-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
