The BMW R 75/5 is a testament to the company’s 46-year history of innovation in motorcycle design. The iconic horizontally opposed twin engine, first introduced in 1923, has become synonymous with smooth, quiet, and reliable performance. Its unique layout offers a blend of cooling and lower center of gravity, resulting in exceptional handling and durability. With its cast iron-lined aluminum cylinders and precision engineering, the R 75/5 boasts an impressive 82mm bore and a reputation for unequaled reliability.
The latest model has undergone a significant redesign, shedding nearly 50 pounds while gaining an electric starter and 150cc’s to boost the engine size to 750cc. The result is a high-performance solo sports bike that has shed its sidecar-hauling image. The one-piece drop-forged crankshaft, plain bearings, and shaft drive ensure a seamless power delivery, while the electric starter adds convenience to the riding experience.
Whether carving through twisty roads or cruising down highways, the BMW R 75/5 delivers a rich, satisfying experience that embodies the essence of motorcycling.
