Built around Yamaha's scooter motorcycle platform, the 2009 Yamaha Zuma 125 pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 52.4 x 57.9 mm (2.1 x 2.3 inches) with a 10.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 6.05-liter (1.6 US gal) fuel tank paired with a rated consumption of 2.64 L/100 km provides an estimated theoretical range of roughly 229 km (142 miles) between fill-ups.
Within MotoLibrary's Yamaha archive, this model family spans 17 indexed model years from 2009 to 2026, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
