The BMW R 69S: a motorcycle that defies convention with its unique blend of power and practicality. Imagine a machine that effortlessly soars across the road surface, its horizontally-opposed twin cylinders resembling stubby wings. This is the essence of the R 69S, a traveling man’s machine that excels at long-distance touring.

The R 69S boasts a potent 593cc engine, featuring 9.5:1 compression, larger carburetors, and more radical cam timing. The result is a peak horsepower figure of 42 DIN at 7,000 rpm, making it the punchier of BMW’s 600cc offerings. However, this is no fireball solo machine – its true strengths lie in its reliability and reserve power, making it an ideal companion for the seasoned traveler.

With its massive, non-sporting design, one might expect the R 69S to be a sedate machine. Yet, it has a fantastic legend among the touring community, thanks to its ability to deliver all-day cruising at the legal limit, or higher if one dares. The R 69S is a testament to BMW’s commitment to building motorcycles that are both rugged and refined, and for those who value reliability and power, it is the ultimate touring companion.

The BMW R62, a motorcycle of unparalleled exclusivity and performance, was the crown jewel of BMW’s lineup in the late 1920s. With a top speed of 70 mph, it was a lightning pace for its time, and its hefty price tag made it a luxury item for the wealthy few who could afford it.

Only 4,355 units were produced, and those who were lucky enough to own one were often doctors, businessmen, and other members of Germany’s upper echelons. The R62’s impressive 745cc engine, producing 18 horsepower, was a marvel of engineering, and its Baukastensystem design, which shared components with the less expensive R52, was a testament to BMW’s innovative approach to manufacturing.

From an industrial design perspective, the R62 is a stunning example of the German Bauhaus philosophy, incorporating elements of architecture, art, and sculpture into its sleek, modernist design. With its 6-leaf spring front suspension and coil spring rear suspension, the R62 was a bike that handled the rough roads of the time with ease.

Today, the BMW R62 remains an iconic symbol of BMW’s rich history and a testament to the company’s commitment to performance, innovation, and style, and it remains a sought-after collector’s item for motorcycle enthusiasts around the world.

The BMW R 65, a quintessential middleweight motorcycle, boasts a 650cc engine that distills the essence of traditional BMW engineering. While its 82mm-bore barrels are shorter than those of its larger brethren, the heads are comparable, resulting in a more compact powerplant. This narrower engine design eliminates the traditional concern of dragging cylinder head covers on the pavement.

The R 65’s engine features a single camshaft, situated below the crankshaft and driven by a single-row roller chain, which transfers motion to the cylinder head-mounted, needle-bearing-suspended rockers via four steel-capped aluminum pushrods. BMW’s innovative design of new valve lifters, where the pushrods sit inside the hollow lifters, practically beside the cam lobes, is a testament to the company’s commitment to precision engineering.

The R 65’s power delivery is smooth and refined, courtesy of a lightweight, single-plate dry clutch and a spring-loaded cush drive assembly. The modular gearbox, identical to that found in 1979 BMWs, provides seamless shifting, while a second cush drive mechanism in the final drive shaft ensures a silky-smooth transmission experience. With its 3.44:1 ratio, the R 65 is perfectly suited for a mix of urban commuting and spirited country roads, making it an ideal choice for riders seeking a balance of comfort and performance.
