Engineered by Yamaha for the scooter motorcycle segment, the 2018 Yamaha Zuma 50FX 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 43.6 mm (1.5 x 1.7 inches) with a 12.0:1 compression ratio.
On the scales, the Zuma 50FX measures 91.2 kg (201 lbs) wet (curb). 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 1,278 mm (50.3 in) wheelbase engineered for quick, flickable steering geometry. The 4.54-liter (1.2 US gal) fuel tank paired with a rated consumption of 1.78 L/100 km provides an estimated theoretical range of roughly 255 km (158 miles) between fill-ups.
