The BMW R80, R90, and R100 motorcycles, produced from 1979 onwards, represent a significant chapter in the history of BMW Motorrad. These air-cooled, boxer-twin engined machines were successors to the highly successful R75/5 and R90/6 models, and marked a shift towards more refined and technologically advanced motorcycles. The R80, with its 797cc engine, offered a perfect blend of performance and practicality, making it a popular choice for both commuting and touring. The R90, boasting a 900cc engine, provided a step up in power and torque, making it ideal for longer journeys and more demanding riding conditions. The R100, with its 980cc engine, was the top-of-the-line model, known for its impressive power and ruggedness. These models were known for their robust construction, featuring a double-loop tubular steel frame, telescopic front forks, and a swingarm rear suspension. They incorporated several advancements over their predecessors, including an improved alternator, a redesigned fuel tank, and a more comfortable rider position. The R80, R90, and R100 were available in a variety of configurations, including standard, “RT” (Touring), “GS” (Enduro), and “S” (Sport) models, allowing riders to choose a bike that best suited their needs. These motorcycles gained a reputation for their reliability, durability, and comfortable riding experience, making them popular among touring riders, commuters, and enthusiasts alike. They became iconic symbols of German engineering excellence and continue to be highly sought after by collectors and riders today.
