Positioned in Honda's scooter motorcycle lineup, the 2011 Honda SH150i relies on a 153 cc (9.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 58.0 x 57.8 mm (2.3 x 2.3 inches) with a 11.0:1 compression ratio.
On the scales, the SH150i measures 137 kg (302 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,356 mm (53.4 in) wheelbase engineered for quick, flickable steering geometry. The 6.81-liter (1.8 US gal) fuel tank paired with a rated consumption of 2.58 L/100 km provides an estimated theoretical range of roughly 264 km (164 miles) between fill-ups.
