The BMW R90, produced from 1978 to 1996, is a classic motorcycle that embodies the German brand's reputation for engineering excellence and timeless design. This air-cooled, boxer-twin motorcycle was a mainstay in the BMW lineup for nearly two decades, winning over riders with its smooth power delivery, robust construction, and exceptional handling. The R90 was a versatile machine, equally at home on winding roads, long-distance touring, or even light off-road adventures. Its iconic silhouette, featuring a low-slung fuel tank, a distinctive twin-cylinder engine protruding from the frame, and a simple yet functional design, has become synonymous with classic BMW motorcycles.

The R90's engine, a 900cc air-cooled boxer-twin, delivered a smooth and responsive power output, making it a comfortable ride for both commuting and touring. The motorcycle featured a robust telescopic fork and swingarm rear suspension, offering a comfortable ride that was surprisingly capable in handling diverse terrain. The R90 was available in various iterations, including the base model, the luxurious RT (touring), and the rugged GS (off-road). Its popularity stemmed from its reliability, ease of maintenance, and its ability to adapt to a wide range of riding styles. The R90's simple design and robust construction made it a favorite among both experienced riders and those new to motorcycling, solidifying its place as a timeless classic in the world of motorcycles.
