Positioned in Yamaha's minibike, cross motorcycle lineup, the 2002 Yamaha PW 80 utilizes a 79 cc (4.8 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 4.8 HP (3.5 kW) at 5,500 rpm while maximum torque reaches 6.3 Nm (4.6 lb-ft) at 5,000 rpm. With a specific output of 60.8 HP per liter and a 500 rpm working window between peak torque (5,000 rpm) and peak power (5,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the PW 80 measures 57 kg (126 lbs) dry. 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.
