Leave the flashy colors and sleek forms to the Italians — the history of BMW Motorrad has been one of form following function. This fully restored 1954 BMW RS 54 factory racer in the company's classic black is a perfect example of that philosophy. With its 45 hp, DOHC 500cc boxer two-cylinder engine, gear-driven solid-shaft final drive — no chains — and Earles-type front fork, the RS 54 sported some of the most advanced technology of the era. And all that engineering showed on the racetrack, with BMW factory riders winning multiple Tourist Trophies and sidecar world championships. Only 24 examples were produced in the 1954 model year, making the RS 54 a rare milestone in the history of motorcycling.
