The BMW R80, R90, and R100 motorcycles, produced from 1977 to 1996, represent a pivotal era in BMW's motorcycle history, marking a transition from the traditional air-cooled boxer engine to a more modern and refined design. These models, particularly the R100, became iconic for their reliable performance, durability, and distinctive styling. Powered by a 980cc air-cooled, horizontally opposed two-cylinder boxer engine, these motorcycles offered a smooth and torquey ride, making them popular among both commuters and weekend riders. The R80, with its smaller 797cc engine, provided a more nimble and fuel-efficient option, while the R90 offered a balance between the two. The R80, R90, and R100 series boasted a range of features that contributed to their success. They featured a telescopic front fork paired with a BMW Paralever rear swingarm, which offered a comfortable and stable ride. The motorcycles were also equipped with a shaft drive system, eliminating the need for a chain and reducing maintenance. These models were known for their robust construction and long service life, making them popular with riders who prioritized reliability and longevity. The R100 in particular achieved cult status, becoming a symbol of classic motorcycle design and engineering in the 1980s and 1990s. With its distinctive boxer engine, chrome accents, and simple yet effective design, the R100 became a sought-after motorcycle, retaining its value and appeal even today.
