In what is an engaging mix of the traditional and the modern, BMW Motorrad has revealed a return on two wheels to the brand’s core but with a modern twist. The BMW Motorrad Concept R18 transports the essence of the big BMW Motorrad classics into the modern age, or taking a historical motorcycle design and giving it a modern, custom attitude.
According to Dr Markus Schramm, head of BMW Motorrad, “With this dream bike, BMW Motorrad presents its own version of an emotional and authentic offer for the large cruiser segment.”
The Concept R18 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 R18 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,” says Edgar Heinrich, head of BMW Motorrad Design.
Purist design with timeless proportions
The BMW Motorrad Concept R18 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 R18 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 R5, 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.
Boxing it all out
The heart of the BMW Motorrad Concept R18 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 R18 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 R18 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.
