Built around Yamaha's scooter motorcycle platform, the 2011 Yamaha PW80 pairs a 79 cc (4.8 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 47.0 x 45.6 mm (1.9 x 1.8 inches) with a 6.6:1 compression ratio.
On the scales, the PW80 measures 61 kg (134 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 635 mm (25 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,055 mm (41.5 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
