Motive Power Industry, maker of PGO scooters, was established in Taiwan in the mid-1960s, making it one of the older names in the island's two-wheeler industry. Over the following decades the company produced machines under its own brand and for other markets, building a reputation for distinctive, characterful designs rather than volume-model uniformity.

PGO became known for sporty scooters at a time when few makers chased real performance, with the G-Max range offering genuine handling, while the PMX served riders wanting compact agility. Retro-styled machines such as the Ligero and the unusual Bugracer buggy show the breadth the range has covered, and the two-stroke versions in particular earned a following among tuning enthusiasts.

A PGO workshop manual covers two-stroke and four-stroke engines in full detail, from cylinder and piston work to complete rebuilds, together with CVT transmission service, carburettor or fuel-injection settings, brakes, suspension and steering. Electrical chapters include wiring diagrams, and torque specifications and service intervals are given for each model. Routine jobs such as belt replacement and roller inspection are described in detail.

Scooter enthusiasts, commuters and workshops servicing Taiwanese machinery will all find the correct data here. Because PGO often adopted interesting engineering solutions, accurate documentation is particularly valuable when diagnosing faults or restoring these characterful machines, and it helps confirm exactly which variant is fitted before parts are ordered.
