Engineered by Yamaha for the scooter motorcycle segment, the 2009 Yamaha Zuma pairs a 49 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. 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.
On the scales, the Zuma measures 93.9 kg (207 lbs) wet (curb). 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 paired with a rated consumption of 1.91 L/100 km provides an estimated theoretical range of roughly 297 km (185 miles) between fill-ups.
Within MotoLibrary's Yamaha archive, this model family spans 6 indexed model years from 2004 to 2013, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
