With the modern BMW Motorrad Concept R 18 /2 Custom Cruiser, BMW Motorrad adds a new facet to the Heritage concept.

The BMW Motorrad Concept R 18 – a purist, historically inspired version of the big boxer – was presented by the BMW Group at the Concorso d’Eleganza in the Villa d’Este at Lake Como in the early summer. Six months later, at the world’s biggest motorcycle show – the EICMA in Milan – BMW Motorrad now presents its second sensational concept bike based on a big boxer engine: the BMW Motorrad Concept R 18 /2 (pronounced: “Slash Two”). It is the stylistic opposite of the Concept R 18: a modern, dynamic custom cruiser with a performance appeal that is somewhat rougher round the edges. As such, the BMW Motorrad Concept R 18 /2 demonstrates yet another potential expression of the Heritage concept, providing an impressive example of the flexibility and wide-ranging customisation options offered by this basic architecture.
The presentation at the EICMA will take place exclusively by means of films and photographs.

“In contrast to the classic, elegant BMW Motorrad Concept R 18, the Concept R 18 /2 draws on its large boxer engine and frame to create a modern custom concept. The Concept R 18 /2 is uniquely extrovert. Elements from the past and future of BMW Motorrad merge here to create a captivating cruiser, making a powerful statement: “It’s a highly emotional bike designed for active riding. At the same time, the Concept R 18 /2 reflects the range of characterisations and customer dreams that we are able to realise using the same backbone,” explains Edgar Heinrich, Head of Design BMW Motorrad.

A performance cruiser à la BMW.
The BMW Motorrad Concept R 18 /2 celebrates the fascination of cruisers in an interpretation that is both sporty and modern. Minimalist handlebar trim together with the deep, elongated proportions promises a dynamic driving experience. The fairing, tear-drop fuel tank and seat form a flowing line that finds its perfect conclusion in the shortened rear wheel cover. All body parts are finished in Candy Apple Red metallic, an expressive red tone that highlights the flowing movement on the side. This luminous custom red with lots of depth is a real eye-catcher, changing from bright red to almost black depending on the incidence of light. Another striking feature is created by the graphic lines on the painted body parts, which extend from the side and top view of the fuel tank to the wheel cover and are visually prolonged across the seat. These give the Concept Bike a distinctive appeal.

The large boxer at the centre.
As in the Concept R 18, the centrepiece of the BMW Motorrad Concept R 18 /2 is a large 2-cylinder boxer engine with 1800 cc, including modern air/oil cooling and designed in a 1960s aesthetic. The engine is finished in a warm grey tone and has a sporty look, with an integrated breast cover, valve covers in a high-gloss black finish and a black frame. The engine badge bears the name of the Concept Bike, adding a high-quality accentuation.
After “Departed” by the Japanese customizer CUSTOM WORKS ZON, “The Revival Birdcage” by Revival Cycles in Austin, Texas and the BMW Motorrad Concept R 18, the BMW Motorrad Concept R 18 /2 is now the fourth interpretation of the large-volume BMW Motorrad boxer engine.

Attention to detail.
As a genuine BMW, the BMW Motorrad Concept R 18 /2 not only features a boxer engine, loop frame and tear-drop fuel tank, it also has a classic and elegantly showcased universal shaft. The striking cast iron wheels with 19” at the front and 16” at the rear create an equally discreet and dynamic dragster look, authentically rounding off the bike’s overall appearance. Meanwhile features such as high-performance Brembo brake calipers and Hattech stainless steel tailpipe system reflect the close attention to detail with which the BMW Motorrad Concept R 18 /2 was designed.

Multitude of possibilities.
The BMW Motorrad Concept R 18 /2 puts forward a new interpretation of a dynamic performance cruiser that not only taps into an area previously unexplored by BMW Motorrad but also demonstrates the true versatility of the “big boxer” platform. “After the BMW Motorrad Concept R 18, our aim with the Concept R 18 /2 is to demonstrate how flexible the basic engine and suspension are as a starting point for customisation, and how easy it is to authentically realise different styles. And I have to admit: we were very impressed at how it was possible to bring this boxer concept forward from the 30s via the 80s into the 2020s,” says Bart Janssen Groesbeek, BMW Motorrad Vehicle Designer for the Big Boxer Concepts.

Against the backdrop of a bustling mix of the traditional and the modern on show at the Concorso d’Eleganza Villa d’Este, BMW Motorrad presents an engaging alternative for a time that is being increasingly characterised by rapid technological change. You could see it as a return to the brand’s core, but given a modern twist: the BMW Motorrad Concept R 18 transports the essence of the big BMW Motorrad classics into the modern age, or in other words, it is taking a historical motorcycle design and giving it a modern, custom attitude. Dr. Markus Schramm, head of BMW Motorrad, describes the design as follows: “With this dream bike, BMW Motorrad presents its own version of an emotional and authentic offer for the large cruiser segment.”

The BMW Motorrad Concept R 18 shows how a forward projection of a 1960s boxer engine could look like today as a purist custom bike in combination with all the classic design icons of BMW Motorrad design. “With its clear aesthetics openly on display, the Concept R 18 embodies for me what motorcycling, at its core, is really about. It is all about feeling instead of thinking, and not using technology for self-staging, instead giving space for imagination. This concept bike appeals to something deep down – you just want to just get on it and ride off. But when you get off it again, you don’t just put it in the garage and walk away – you turn around again and give it a final parting glance”, explains Edgar Heinrich, head of BMW Motorrad Design.

Consistently purist design with timeless proportions.
The BMW Motorrad Concept R 18 is the essence of motorcycling, a bike in its original, natural form. In true custom style, it celebrates the art of leaving out what you don’t need and then concentrating on what is left. “The biggest challenge in the design is to render everything visible. Every part has a functional purpose. There are not many who would dare to take such an absolutely honest approach”, says Bart Janssen Groesbeek, designer of the concept bike. The BMW Motorrad Concept R 18 is immediately recognisable as a genuine BMW: boxer engine, cradle frame, exposed universal shaft and drop-shaped fuel tank with its black paintwork and hand-applied contrast lines interpret typical design icons of BMW Motorrad classics, while displaying confidence along with modern-style linearity. The balanced proportions are reminiscent of classics like the BMW R 5, and convey – even from a distance – the timeless beauty that comes about whenever things are consistently reduced to their bare essentials. The frame and tank create a common line all the way from the steering head to the rear wheel hub and lend a flowing elegance to the side view. The large spoke wheels (front 21 inch, rear 18 inch) provide a secure stance and perfectly balance the dominant power unit. The tyres are a further reference to history: just as it was in its day, this bike is again fitted with Metzeler tyres.

The BMW boxer tradition brings out new splendour.
The heart of the BMW Motorrad Concept R 18 is the large, newly designed, two-cylinder 1800 cc boxer engine. Its outward appearance is consciously reminiscent of the flat twin engines that BMW Motorrad used to build up until the end of the 1960s – but with a considerably bigger displacement and modern air/oil cooling. The big prototype boxer has been designed down to the last detail: the engine block and transmission are made of glass bead-blasted aluminium, providing an ideal stage on which to present the hand-polished aluminium components as well as the belt guard and valve covers. The engine badge bears the name of the concept bike and emphasises the overall quality. In addition, Solex dual carburettors – similar to those in the BMW 2002 – hark back to the brand’s construction history and add the final touch to the bike’s visual authenticity.

Another optical highlight is the exposed, chrome-plated universal shaft that connects the back wheel to the drive. There are no further covers anywhere on the motorcycle, which serves to keep its engineering clearly visible. Similarly, the electronics of the concept bike are reduced to no more than starter and lights, underlining its purist design.

The BMW Motorrad Concept R 18 is the third in-house interpretation of the large-capacity boxer engine to come from BMW Motorrad. Last December the model created by the Japanese customisers, CUSTOM WORKS ZON was presented at the Yokohama Hot Rod Show, on the basis of this new prototype engine. The ‘Departed’ won the biggest accolade of the event, the ’Best of Show Motorcycle’ award, thrilling motorcycle fans with its classic forms, modern production techniques and all manner of manual art and craft in the details. The next round was the interpretation by Revival Cycles.

The customisers from Austin, Texas created a spectacular bike with their ‘Revival Birdcage’ model, an ideal presentation platform for the Big Boxer. The specially developed titanium frame features an unobstructed view of the engine and drive from all angles. This American design created a furore at last month’s Handbuilt Show in Texas.

High quality details in fine custom work.
As for its colour design, the BMW Motorrad Concept R 18 shows itself to be a classic. The theme is typical BMW: the white, hand-applied lines on the fork and fuel tank in combination with the black base colour represent the classic BMW colour theme. A discreet yellow-gold varnish effect lends the bright twin lines an exclusive touch, and the black effect paintwork on the tank and fork rods similarly reveal, in the best custom style, an unusual depth when the sunlight strikes the large metallic particles in the various layers of the paintwork.

The visual design of the imprinted single leather seat is borrowed from the classics of the 1950s. Reinterpreted and somewhat more comfortable, its quality embossing sits perfectly within the overall purist and high-class design. The cantilever spring strut is integrated beneath the seat. The graphics of the headlamp design are also reminiscent of the 1950s. The classic U shape of the original glass cover components are now interpreted as LED lamp elements.

Every one of these details contributes to the unique character of the concept bike and underlines its overall statement. The BMW Motorrad Concept R 18 merges traditional and historic design language with the current functionalities of BMW Motorrad in a coherent and cohesive whole.

Moreover, an exclusive and suitably themed horse leather jacket, which recreates the aesthetics of those days, has been designed especially for the presentation of the concept bike at the Concorso d’Eleganza Villa d’Este. The leather jacket features a very smooth surface with only little grain and the protectors are integrated almost invisibly.

A counterpoint to contemporary times.
“For me, motorcycles like the BMW Motorrad Concept R 18 are a response to a growing need among the motorcycling community: instead of technology, the focus here is on simplification, authenticity and transparency. I observe an almost romantic yearning for real mechanical engineering. Our aim with this concept bike is to address this need and turn it into an analogue statement in a digital age. We have a rich history of iconic motorcycles, and they all bear the same design characteristics. We believe that this can still work well together today with the current technology,” says Edgar Heinrich in conclusion.
