Technical Overview
2017 Yamaha Zuma X Technical Analysis & Specification Breakdown
At the heart of the 2017 Yamaha Zuma X scooter motorcycle, Yamaha 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 X measures 91 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 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank paired with a rated consumption of 1.82 L/100 km provides an estimated theoretical range of roughly 247 km (153 miles) between fill-ups.
