Overview

Introducing the 1964 Aermacchi Chimera 250: a striking representation of Italian craftsmanship and engineering that captures the spirit of the early '60s motorcycle culture. This sport motorcycle, born from the collaboration between Aermacchi and Harley-Davidson, was designed to appeal to the burgeoning market of young riders seeking both performance and style. With its sleek lines and agile demeanor, the Chimera 250 positioned itself as a nimble contender in the sport segment, offering an exhilarating riding experience that still resonates with enthusiasts today. At the heart of the Chimera 250 is its robust single-cylinder, four-stroke engine, boasting a displacement of 246 cc. With a power output of 13.7 horsepower at 6,500 RPM, this engine delivers spirited performance that allows riders to reach a top speed of 120 km/h (74.6 mph). The well-tuned air-cooled powerplant features a compression ratio of 7.0:1, providing a balanced mix of torque and responsiveness. Riders will appreciate the smooth delivery of power, thanks to the Dell'Orto carburettor that ensures optimal fuel mixture. The lightweight chassis, weighing in at just 125 kg (275.6 pounds), enhances the Chimera's agility, making it an ideal motorcycle for navigating tight corners and city streets with ease. The Aermacchi Chimera 250 is not just about performance; it also incorporates thoughtful design elements that enhance the riding experience. The motorcycle features classic drum brakes at both the front and rear, providing dependable stopping power that is well-suited for spirited riding. Its kick starter adds an element of nostalgia, harkening back to a time when riders truly connected with their machines. The combination of a chain final drive and a compact bore and stroke of 66.0 x 72.0 mm ensures that the Chimera can deliver a thrilling ride whether you're commuting or enjoying a weekend escape. The marriage of aesthetics and engineering makes the Chimera a standout piece of motorcycle history. **
