2012 Sym Symphony SR 150 Technical Analysis & Specification Breakdown
Built around Sym's scooter motorcycle platform, the 2012 Sym Symphony SR 150 utilizes a 140 cc (8.5 cu in) air-cooled single cylinder, four-stroke layout.
On the scales, the Symphony SR 150 measures 100 kg (220 lbs) dry. Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank paired with a rated consumption of 2.17 L/100 km provides an estimated theoretical range of roughly 253 km (157 miles) between fill-ups.
