Positioned in Honda's scooter motorcycle lineup, the 2011 Honda PS150i relies on a 149 cc (9.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 11.5 Nm (8.5 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 52.4 x 57.8 mm (2.1 x 2.3 inches) with a 11.0:1 compression ratio.
On the scales, the PS150i measures 157 kg (346 lbs) dry. Rider ergonomics and chassis geometry center around a 776 mm (30.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
