The PGO PA-100 and PA-125 are lightweight scooters produced by the Taiwanese manufacturer PGO (PGO Motor Co. Ltd.) in the early 2000s. These stylish and compact scooters were designed for urban commuting and recreational riding, catering to a broad audience, particularly younger riders. The PA-100 and PA-125 share a similar design and chassis, with the main difference lying in their engine displacement. As indicated by their names, the PA-100 features a 100cc, single-cylinder, air-cooled engine, while the PA-125 boasts a slightly larger 125cc engine, offering more power and performance. Both engines are known for their fuel efficiency and reliability, making them suitable for daily use. The PGO PA-100 and PA-125 are characterized by their lightweight construction, typically less than 100kg, making them easy to maneuver and handle. They feature a comfortable and ergonomic riding position, with a wide, comfortable seat and a low center of gravity for stability. Although lacking in advanced features found in modern scooters, the PA-100 and PA-125 are practical and functional, equipped with essential features like a front disc brake and rear drum brake for safe stopping, a luggage rack for carrying small items, and a fuel gauge for monitoring fuel levels. They are also relatively inexpensive to maintain, making them an attractive option for budget-conscious riders. While these scooters may not be as powerful or feature-rich as newer models, they still offer a reliable and enjoyable riding experience, especially for urban commuting or short-distance rides.
