The BMW R80, R90, and R100 motorcycles, produced between 1977 and 1996, represent a crucial chapter in the history of BMW Motorrad. These air-cooled, boxer-twin engined machines epitomize the brand's enduring commitment to engineering excellence and timeless design. The models, known collectively as the "Airheads," were the successors to the iconic /5 series and further honed the formula that had propelled BMW to motorcycle prominence. The R80, R90, and R100, however, went beyond mere refinements. These models saw the introduction of features that would become synonymous with BMW motorcycles, including the monoshock rear suspension, a fuel-injected version of the boxer engine, and a redesigned, more rigid frame. The R80, with its 798cc engine, was the entry-level model, while the R90 and R100 boasted larger displacements of 898cc and 980cc respectively, delivering punchier performance and greater touring capability. The R80, R90, and R100 were available in a variety of configurations, each tailored to specific rider needs. The "R" designation denoted a "Roadster" model, often considered the base configuration. This basic platform served as the foundation for other models like the "RT" (Touring), "GS" (Enduro/Adventure), and "RS" (Sport) variants. Each of these models incorporated unique features and modifications to further enhance their specific riding experience. The Airheads gained immense popularity for their reliability, rugged construction, and inherent simplicity. Their smooth and powerful boxer engine, coupled with comfortable ergonomics, made them ideal for both leisurely weekend rides and long-distance touring. The Airheads also established a reputation for their robustness and ability to tackle challenging terrain, thanks to their strong frame, durable suspension, and ample ground clearance. Today, these motorcycles are highly sought after by collectors and enthusiasts alike, serving as a reminder of a golden era in motorcycling history.
