BMW R60/5: Production & Legacy

The Enduring Appeal of the BMW R60/5

The BMW R60/5 stands as a significant milestone in the history of BMW Motorrad. As the first model to be entirely assembled at BMW's then-new Berlin facility, it represented a new era for the German manufacturer. Introduced as part of the /5 series, which also included the R50/5 and R75/5, the R60/5 quickly established itself as a capable and well-regarded motorcycle. This article delves into the production figures of the R60/5, its place within the broader /5 and /6 lineage, and what makes these 'Airhead' BMWs so special to enthusiasts and custom builders alike.

Production Figures: How Many R60/5s Were Built?

A key question for many classic motorcycle enthusiasts is the rarity and production numbers of their beloved machines. For the BMW R60/5, the numbers are quite substantial, indicating its popularity during its production run. In a period of five years, a total of 22,721 R60/5 models were manufactured. This figure underscores the success of the /5 series and BMW's commitment to expanding its motorcycle production capabilities in Berlin.

The /5 Series: A New Beginning in Berlin

The /5 series, launched in 1969, marked a pivotal moment for BMW. Prior to this, BMW motorcycles were largely built at their Munich plant. The relocation and expansion to the Berlin facility allowed for increased production capacity and the introduction of new models. The R60/5, with its 599cc boxer-twin engine, offered a balance of power and touring capability that appealed to a wide range of riders. It was a departure from earlier BMW models, featuring a more modern design and improved performance. The horizontally-opposed twin engine, a hallmark of BMW motorcycles, was refined for the /5 series, laying the groundwork for decades of development.

Evolution to the /6 Series: The R60/6 Emerges

The /5 series paved the way for the next generation of BMW boxers, the /6 series. The BMW R60/6 was first released in 1974, succeeding the outgoing /5 models. While BMW is known for its incremental improvements rather than radical redesigns, the /6 series brought notable updates. The R60/6 shared many components with its predecessors but featured enhancements that improved performance and reliability. The /6 range included the R60/6, R75/6, R90/6, and the sporty R90S. The nomenclature itself tells a story: the first two digits indicate engine displacement (approximately), and the number after the slash denotes the generation. Thus, the R60/6 is a 600cc '6-series' model.

Technical Specifications and Performance of the R60/6

The R60/6, despite being the smallest in the /6 family, was a popular choice for those seeking a versatile middleweight motorcycle. Its 599cc boxer-twin engine produced a respectable 40 horsepower and 36 lb-ft of torque. With a top speed of around 103 mph and the ability to comfortably cruise at 80 mph on the Autobahn, it was well-suited for both commuting and longer journeys. The engine design, while relatively simple, was renowned for its bulletproof reliability. Like all /5 and /6 series bikes, it featured a unit construction engine, shaft drive, telescopic front forks, and twin rear shock absorbers. The frame design also bore a resemblance to the iconic Norton Featherbed frame, hinting at its capable handling characteristics.

Production Lifespan of the /6 Series

The /6 series BMWs were produced from 1974 until 1976, making way for the /7 series in 1977. Despite this relatively short production run, the /6 models remain a common sight on the roads and are highly sought after by collectors and custom builders. Their enduring appeal lies in their classic styling, dependable performance, and the vast availability of aftermarket parts, making them ideal platforms for customization.

The 'Airhead' Phenomenon: More Than Just a Motorcycle

The term 'Airhead' refers to BMW motorcycles from the mid-1970s through the early 1990s that featured air-cooled boxer engines. These motorcycles, including the R60/5 and R60/6, have cultivated a dedicated following. Their unique character, robust engineering, and the sheer joy of riding them have cemented their place in motorcycling history. The engine, perfected over decades, is not just a mechanical component but the heart and soul of the bike.

Restoration and Customisation: A Case Study of the R60/5

The world of classic motorcycle restoration often presents a mix of immense satisfaction and daunting challenges. One owner's journey with a 1973 R60/5, nicknamed Beatrice, highlights this perfectly. Purchased as a winter hack, the R60/5 eventually became the subject of an extensive rebuild. The process involved addressing common issues such as smoke on the overrun, ring gap, and the need for more power. Modifications included a big bore kit, twin-plug conversion, deep sump, and upgraded ignition systems. The restoration also involved significant bodywork and paint preparation, including a replica R90S paint scheme.

Challenges and Triumphs in Restoration

Working on these vintage machines often involves unexpected hurdles. This particular R60/5 project encountered issues with fork seals, brake upgrades, and even a damaged fuel tank that required specialist repair and a courier-induced repaint. The sheer weight of the boxer engine also posed a significant challenge during reinstallation, requiring creative solutions. Despite these setbacks, the owner persevered, driven by the desire to create a unique and personalised machine. The final result was a beautifully restored R60/5, a testament to the owner's dedication and the inherent charm of the 'Airhead' platform.

Custom Builds: The Vintage Steele R60/6 Example

The versatility of the R60/6 as a base for custom builds is exemplified by the work of Vintage Steele. For a customer seeking a scrambler-styled, daily-rideable motorcycle, Vintage Steele undertook a project that pushed creative boundaries. This build featured a significant upgrade to the front end, incorporating forks, hub, and brakes from a 2011 Suzuki GSXR 600 for improved handling and stopping power. The rear suspension geometry was adjusted, and Öhlins piggyback shocks were fitted. A new wiring loom, LED headlight, and modern gauges, including a GPS speedometer, were installed.

Unique Touches: Glass Emblems and Bespoke Paint

What truly set this Vintage Steele R60/6 apart were the bespoke design elements. The owner, a professional glassblower, collaborated with an artist to create a unique paint scheme and custom glass emblems for the fuel tank. These subtle yet distinctive touches transformed the classic BMW into a truly one-of-a-kind machine. This approach showcases how the R60/6, with its iconic engine and timeless design, continues to inspire creativity within the custom motorcycle scene.
