The BMW R850R and R850GS, launched in 1999, were significant motorcycles in the BMW lineup, marking a generational shift in the brand's renowned boxer-twin engine technology. The R850R, a naked roadster, offered a sporty and engaging ride for everyday use, while the R850GS, an adventure tourer, was built for tackling diverse terrain both on and off-road. These models were powered by a newly designed 850cc air-cooled, horizontally opposed twin-cylinder engine boasting fuel injection and a five-speed gearbox. The engine produced a healthy 75 horsepower, making these bikes both powerful and efficient. The R850R, with its low-slung design and sport-tuned suspension, provided a thrilling experience on winding roads, while the R850GS, featuring long-travel suspension, spoke wheels, and a high-mounted exhaust, was capable of tackling even the most challenging off-road adventures. Despite their distinct personalities, the R850R and R850GS shared several key features. Both models featured a double-loop steel frame, telescopic forks, and a single-sided swingarm with a monoshock rear suspension. The braking system utilized a dual disc setup at the front and a single disc at the rear, enhancing stopping power. The R850 series was also praised for its ergonomics, offering a comfortable and upright riding position with a spacious seat and well-placed controls. The inclusion of a fuel gauge and a digital clock added practicality to these bikes.
