L’éveil électrique du moteur boxer.
Munich. For more than 90 years, the 2-cylinder
boxer engine has been a key element of the BMW Motorrad identity,
in both technological and visual terms. But as the BMW Group
consistently pursues electrification, the question arises as to
what a BMW motorcycle might look like that is electrically
powered? And how would it reveal itself at first sight to be a
BMW? One possible answer to these questions is provided by the BMW
Motorrad Vision DC Roadster, a highly emotional naked bike with
“The boxer engine is the heart of BMW Motorrad – an absolute
stalwart of its character. But BMW Motorrad stands for visionary
zero-emissions vehicle concepts, too. In view of this, one
question that arises is: what would happen if we were to replace
the boxer engine with an electric motor and the required battery?
The Vision Bike shows how we’re able to retain the identity and
iconic appearance of BMW Motorrad in distinctive form while at the
same time presenting an exciting new type of riding pleasure,”
explains Edgar Heinrich, Head of Design BMW Motorrad. “After all:
anyone who’s ever tried it out in practice knows very well that
riding on two wheels is just as exciting when its electrically
powered! The high level of torque right at set-off makes for
breath taking acceleration. This almost brutal power delivery
creates a whole new experience of dynamic performance. And the BMW
Motorrad Vision DC Roadster puts a face to this experience.”
New drive, familiar appearance.
In a motorcycle, the motor is the centrepiece – it is the
fundamental element, providing the basis for the entire
architecture. But electrical drive components have completely
different requirements in terms of installation space. While in a
conventional motorbike the size of the engine is mainly determined
by its capacity, it is the battery that takes up most space in the
case of an electrically powered vehicle. The electric motor itself
is relatively compact. Starting from this new basis, the BMW
Motorrad Vision DC Roadster is able to make this transfer –
retaining the iconic appearance of a boxer while filling it with a
new function. This is why the Vision Bike is instantly
recognisable as a BMW motorcycle, revealing its electric nature on
Replacing what would previously have been the
engine, there is now a vertically fitted, longitudinally oriented
battery. For cooling purposes, two side elements protrude with
cooling ribs and integrated ventilators. As in the boxer engine of
the BMW R 32 – the development of which was masterminded by Max
Friz in 1923 – the cooling elements are placed in the air stream.
The cylinder-shaped electric motor is positioned underneath the
battery and is directly connected to the universal shaft. The BMW
Motorrad Vision DC Roadster thus demonstrates a clever drive
architecture that visually echoes the history of BMW Motorrad
while at the same time taking it a step further.
Dynamic performance reflected in the proportions.
In the side view, the BMW Motorrad Vision DC Roadster presents a
highly dynamic gesture with clear front-wheel orientation. The low
front section and the short, high rear convey a sense of agility.
Instead of the fuel tank, a flat, finely-wrought tubular structure
spans the vehicle corpus. Its further shaping integrates the seat
in a modern form, thereby creating the flyline of a sporty
roadster. The frame structure is a key factor in defining the
dynamic side view.
The large battery with its laterally protruding cooling systems
is positioned at the centre of a frame milled from aluminium. The
three-dimensional surface finish on the battery trim conveys a
contemporary aesthetic appeal with its precise contours. The
cooling elements echo the slight forward tilt of the battery
silhouette, giving the side a dynamic momentum. When starting the
electric motor, these cooling elements move out slightly,
indicating that the bike is ready to go.
High performance with a light touch.
The overall appearance of the BMW Motorrad
Vision DC conveys a sense of lightness so as to emphasise driving
dynamics. Elements such as the seat and the cooling system appear
to hover around the battery. On the frame itself, lengthwise
milled grooves create a fascinating visual effect, reducing the
perceived volume and highlighting the bike’s longitudinal
dynamics. This impression is further underscored by means of
openings in the milled aluminium frame and the tubular frame
structure arranged above it. High-tech materials such as carbon
fibre and aluminium reduce the overall weight and give the BMW
Motorrad Vision DC Roadster a technical aesthetic. Meanwhile, red
contrast elements and brushed aluminium at selected points such as
the battery, frame and cool systems emphasise the bike’s
High-quality details on closer inspection.
A key element of the BMW Motorrad Vision DC Roadster’s
captivating overall appeal is the elaborate finish to be found in
all its details. Within the mainly dark colour concept, it is the
mechanical elements such as the exposed universal shaft and the
Duolever fork that add striking accentuations. In this case, the
two classic BMW features are re-interpreted and elaborately
showcased. In the same way, the suggested triangular frame echoes
a typical feature of earlier BMW motorcycle models, even
recapturing its white lines, which in this instance fluoresce in
the dark. The minimalist design of the front and rear lights is an
iconic implementation of the hallmark BMW Motorrad lighting,
reflecting maximum reduction in modern style. The headlamp shows
the LED daytime riding light in a dynamic, flat U shape, while two
compact LED lenses on each side provide the low and high beam.
This creates a hallmark lighting design that makes the concept
vehicle instantly recognisable as a BMW motorcycle – both during
the day and at night. The rear light consists of two C-shaped LED
elements which are integrated in the aluminium rear carrier in
minimalist, technically high-quality form. On the flanks of the
tires exclusively made by Metzeler for the Vision Bike, five
fluorescent elements, each about the size of a postage stamp, are
integrated. They combine innovative design with safety aspects:
standing and moving, the lighting elements create an exciting
graphic effect. In darkness, they increase the visibility from the
side and thus providing more security. They also convey dynamics
when in motion.
Smart rider equipment.
The functional two-piece suit is not instantly recognisable as
protective clothing: it is an outfit that primarily stands as a
modern, emotional fashion statement. The light jacket with large
graphics in iridescent colouring and the casually styled black
trousers combine fashion sense with new functionalities. The
protectors are sewn in almost invisibly, while integrated
technologies enable various light functions as well as the digital
connectivity of the future. An asymmetrical rucksack vest rounds
off the rider equipment for the vision vehicle. Fixed to the
jacket by means of magnets, it provides storage space and
additional functionality. The permanent magnets means that the
rucksack is quick to put on and take off.
Symbol of a new generation.
The BMW Motorrad Vision DC Roadster is a visionary symbol of the future of BMW Motorrad with alternative drive forms. It showcases the electrically powered driving experience in honest, authentic form, in particular creating a new, distinctive aesthetic appeal that is still firmly rooted in the finest BMW tradition.
