The Aprilia Rotax 655 EFI engine, a powerful and technologically advanced powerplant, was a hallmark of several Aprilia motorcycles produced in the early 2000s. This liquid-cooled, four-stroke, single-cylinder engine, renowned for its robust construction and responsive performance, was designed by the Austrian engine manufacturer Rotax, a subsidiary of Bombardier Recreational Products (BRP). The 655cc displacement, coupled with the fuel injection system, delivered a generous torque output, making these Aprilia motorcycles incredibly capable on the road. Though not widely known for extreme horsepower figures, the Rotax 655 EFI excelled in providing a smooth and consistent power delivery, making it ideal for everyday riding and longer journeys. The Rotax 655 EFI found its home in several Aprilia models, including the Pegaso Strada and the Pegaso 650, two popular adventure motorcycles. These motorcycles were highly regarded for their combination of on-road comfort and off-road capability. The 655 EFI engine's reliability and durability ensured that these adventure bikes could handle the rigors of long-distance travel, while its responsiveness allowed for spirited handling on twisty roads. While the Rotax 655 EFI has been discontinued in favor of newer engine designs, it remains a testament to Aprilia's commitment to crafting motorcycles with a blend of performance, practicality, and reliability. The availability of a Factory Service Repair Manual for this engine underscores Aprilia's dedication to providing the tools and resources necessary for owners to maintain their motorcycles to the highest standard.
