BMW R 100R (1991 – 92)

BMW R 100R (1991 - 92)

The BMW R 100R is a thought-provoking exercise in contrasts, blending the old with the new in a way that’s uniquely BMW. At its heart lies a 1000cc boxer engine, a design dating back to the 1920s, yet updated with modern fuel injection and an emissions afterburning circuit. Paired with Showa suspension and Brembo brakes, this retro-styled bike is anything but antiquated.

Its rounded-off valve covers and distinctive design make the R 100R a true standout in the world of motorcycling. The 40mm Bing carbs provide a perfect blend of power and control, while the paralever and electronic diagnostic equipment add a layer of sophistication. Whether you’re drawn to its nostalgic charm or its cutting-edge technology, the R 100R is an experience unlike any other.

The result is a bike that defies categorization, sitting comfortably in the space between old and new, retro and modern. With its unique blend of heritage and innovation, the BMW R 100R is a true original, a testament to the brand’s willingness to push boundaries and challenge conventional wisdom. It’s a bike that will leave you questioning what a motorcycle should be.
