The BMW R63 stands as a testament to a bygone era of motorcycle engineering and design. As the flagship model in BMW’s 1928 lineup, it was the first time the German manufacturer ventured into the realm of 750cc overhead valve (OHV) motorcycles. This machine was not just a motorcycle; it was a statement of luxury and advanced engineering, placing it in the same price bracket as a Brough Superior in the UK. Its rarity, especially in the USA, only adds to its allure and high value among collectors today. The technical specifications of the R63 were indeed remarkable for its time; 750cc OHV engines were a rarity on public roads in 1928, particularly in the American market, with only a select few high-end or sports models in Europe and the UK boasting such powerful engines.

The Allure of Bauhaus Design in the R63
Beyond its technical prowess, the BMW R63 captivates with its distinctive styling. Embodying the Bauhaus design ethos, the R63 is characterized by its spare, light lines and functional beauty. The ‘flat tank’ design, nestled neatly between the frame rails, along with the purposefully designed engine, contributes to its aesthetic appeal. This design language sets the R63 apart, giving it a lighter and more athletic appearance compared to BMW models that followed in the 1930s, which adopted pressed-steel frames and a more Art Deco style. The R63 remains highly sought after not only for its engineering but also for its iconic and timeless design.
A Personal Encounter and the Reality of a Restored Classic
My own experience with a BMW R63 began with high expectations, fueled by its stunning appearance in photographs. Having sold a Brough Superior SS100 and other motorcycles to purchase a house in San Francisco in 2001, I found myself with enough funds to acquire what seemed to be a beautifully restored 1928 BMW R63 from Germany. However, reality soon struck a discordant note. Despite its visual appeal, it became clear that the restoration was skin deep, aimed at display rather than actual riding. The mechanical cacophony emanating from the engine was likened to a cement mixer, the handling was clumsy, the brakes were ineffective and noisy, and the gearbox emitted a persistent whine. My disappointment was profound. Although the vendor had advised a test ride, the distance made that impractical, and I proceeded based on trust and visual appeal, a decision I came to regret. The rapid resale of the bike by the vendor, despite its flaws, underscored the strong demand for R63s, even those imperfectly restored.
What a beauty! The BMW R63 is from the ‘flat tank’ era of BMW design, with the fuel tank nestled beneath the top frame rails. A spare, Bauhaus-style design, with a 750cc OHV motor that was the most powerful machine available from BMW.
Reflections on Riding a True 1920s BMW
My initial negative experience, however, was not indicative of the potential of 1920s BMW motorcycles. Having since ridden other, well-sorted BMWs from the same era, including the R16, a more nuanced understanding emerged. While even well-maintained R63s might feel somewhat less refined compared to later BMW models starting from the R5 in 1936, they possess their own distinct character and capabilities. The R63 features a leaf-spring front fork with a substantial 7-inch front brake, while the rear brake, a less effective clamp on the shaft drive coupling, leaves something to be desired, especially in wet conditions. The three-speed gearbox can be challenging with its “graunchy” shifts, a characteristic BMW improved upon much later. Nevertheless, the 24hp 750cc engine delivers ample torque and achieves a respectable top speed of around 75mph. While this might not be groundbreaking compared to some high-performance British bikes of the same period – such as the AJS K7, Sunbeam Model 90TT, and Norton Model 18 – the R63 was likely on par with American motorcycles of the era in terms of handling. The British bikes, particularly Nortons and Sunbeams, were renowned for their superior handling and lighter, quicker nature, dominating racing circuits at the time.
The Grand Touring Spirit of the R63 and its Racing Legacy
In conclusion, the BMW R63 is not designed to be a high-speed racer but excels as a beautiful grand touring machine. Its strengths lie in its robust engine, distinctive design, and historical significance, rather than outright performance compared to sportier contemporaries. The R63 also served as the foundation for BMW’s successful WR750 racing machines, which, with supercharging and streamlined bodies, achieved speeds of up to 135mph, demonstrating the inherent potential within the R63’s design.
Lest we forget: Ernst Henne in September 1929 on a BMW WR750 supercharged for record-breaking: he reached 134.67mph on the Ingolstadt autobahn.
The enduring appeal of the R63 is undeniable. The image of a German mechanic regularly riding his R63 from Munich to Turkey exemplifies the reliability and touring capability of this classic machine. For those who appreciate vintage motorcycles, the BMW R63 remains a coveted piece of engineering and design history, offering a unique riding experience steeped in the Bauhaus aesthetic and early BMW innovation.
