The Aprilia Pegaso 650, a motorcycle that graced the roads from 1996 to 2009, embodied the spirit of adventure and versatility. This single-cylinder, fuel-injected machine was built around a robust steel trellis frame and a 650cc, four-stroke engine renowned for its robust torque and eagerness to rev. It was available in two variants: the standard Pegaso 650 and the more off-road oriented Pegaso 650 Trail. The former offered a more road-oriented character with its 17-inch wheels and less aggressive suspension, while the latter, with its 19-inch front and 17-inch rear wheels, was designed to tackle rough terrain with greater ease. This versatility, coupled with a comfortable, upright riding position, made the Pegaso 650 a popular choice for commuters, weekend adventurers, and even seasoned off-road enthusiasts.

The 2003 model year saw a significant update to the Pegaso 650, with a revised engine, a new fuel injection system, and a redesigned exhaust system. These changes aimed to enhance performance, improve fuel efficiency, and reduce emissions. The engine, now with a larger bore and shorter stroke, delivered a smoother power delivery and a more responsive throttle. The revised exhaust system not only contributed to increased performance but also added a unique, throaty sound to the Pegaso's character. The redesigned fuel injection system, coupled with the improved engine, ensured a more consistent and efficient fuel burn. These modifications, along with the Pegaso's already proven reliability and its comfortable ergonomics, solidified its place as a well-rounded and capable motorcycle, ready to tackle any adventure thrown its way.
