The following information is an English translation of the German press kit and some information and specifications may not apply to the U.S. models. This press release will provide you with general and technical information regarding the introduction of the new BMW R 1200 S, K 1200 GT and F 800 ST. Further information and dates of expected U.S. availability will be provided at a later date. ------------------------------------------ 1. Concept and Features. 2. Equipment. 3. Engine Output and Torque of the R 1200 S. 4. Specification.
1. Concept and Features.
Introducing the new R 1200 S, BMW Motorrad is proudly presenting the most
powerful production Boxer the world has ever seen - a machine standing out
clearly from all other models in the range. This new addition to the Boxer
series is following in the footsteps of the successful R 1100 S, with the focus
clearly on sporting performance and dynamic riding characteristics.
This expression of superior performance and sporting power is borne out from
the start by the athletic looks of the R 1200 S: From the front fairing with
the "kidney" grille so typical of BMW and the asymmetric dual headlights all
the way to the unmistakable silencer at the rear and the LED tail lights,
each and every line and feature of this new model simply exudes power and
dynamism all the way.
BMW Motorrad quite intentionally chose the former model as the benchmark in
creating the design of the new R 1200 S. And together with this distinctive
legacy, the responsible designers were able to successfully bring out a
particular touch of lightness and dynamism in the looks of the new machine -
not least thanks to its more slender and perhaps even more athletic silhouette
bearing clear testimony to the outstanding lightweight technology of the
R 1200 S: Overall weight of the new machine in road trim but without fuel is a
mere 195 kg or 430 lb, making it 13 kg or almost 29 lb lighter than its
1,100-cc predecessor. And with the tank full, overall weight of BMW's new
Sports Boxer is an equally impressive 213 kg or 470 lb.
Modified in numerous important features, the 1,170-cc engine offers
enormous power reserves reaching a peak of 90 kW/122 hp at 8,250 rpm. These
figures alone underline the sporting standard of the new model,
which nevertheless does not seek to be a supersports. Rather, one of the most
important objectives in developing the new R 1200 S was to achieve
a perfect synthesis of sportiness and everyday riding qualities enabling
the rider to take on a relaxed seating position for effortless riding enjoyment
even on long distances. And thanks to its slender waist - a result of the
seat configuration optimised around the rider's legs - the R 1200 S also
provides safe and secure ground contact when at a standstill.
It almost goes without saying that BMW's new Boxer comes with all the
features so typical of the brand, such as a fully controlled catalytic
converter, the single-wire system for the on-board network complete with an
electronic immobiliser, a smooth and easy-shifting six-speed gearbox,
maintenance-
free shaft drive with a single swinging arm, as well as Telelever front wheel
suspension. The specific set-up of the suspension and running gear ensures
extremely precise and smooth handling at all times further enhanced by
the high-performance brake system: Optional BMW Motorrad ABS anti-lock brakes
combine low weight and fast response simply perfect for the sports rider - in
this case without the integral function but with on-demand operation allowing
the rider to deactivate ABS on the race track.
The wide range of BMW options and accessories also reflects the customer's
wishes and special requests. The enthusiast seeking to highlight the looks
of his machine as a sporting performer, for example, while at the same time
enjoying each and every bend in the road, has - to mention just two examples -
the choice of an extra-wide rear wheel as well as the high-performance Öhlins
sports suspension with spring struts variable in length.
The most sporting and dynamic Boxer of all times is ready to go!

Boxer engine with even more power.
BMW's new Sports Boxer benefits from the innovations already featured on the R
1200 GS: Displacing 1,170 cc, the two-cylinder features four valves and two
spark plugs per cylinder, thus following the basic principle of the flat-twin
power unit of the GS model. But at the same time far-reaching modifications
ensure much higher peak output than on the RT and ST models. Particularly
the modified cylinder heads enable the R 1200 S to develop an impressive 90
kW/122 hp smoothly delivered to the crankshaft running in anti-friction
bearings. Power is transmitted via new, high load-resistant connecting rods
made of extra-strong steel alloy. The camshafts with modified control timing
and larger valve lift rotate no longer in two, but rather in three bearings
serving to further enhance the stiffness and precision of the entire valve
drive system. Harder valve springs and reinforced rocker arms take the high
speed of the engine of up to 8,800 rpm into account, a speed level incidentally
never seen before on a BMW Boxer.
New pistons are also one of the significant changes made on the S power unit,
increasing the geometric compression ratio to 12.5 : 1 and thus marking
a new record for an air- and oil-cooled power unit. This enormous compression
ratio serves in particular to boost torque at low and medium engine speeds, the
flat-twin developing maximum torque of 112 Newton-metres or almost 83 lb-ft at
6,800 rpm, despite the emphasis on supreme peak power. On the road, this means
supreme engine response and muscle at all times, the flat-twin developing its
maximum output on premium plus (RON 98) fuel. And at the same time the engine
is also able to run smoothly on 95-octane premium thanks to its anti-knock
sensors, with only a minor reduction of power.
Throttle butterflies and intake manifolds enlarged in diameter by 5 millimetres
or 0.20'' to 52 millimetres or 2.05'' and interacting with the modified intake
funnel to boost the cylinder charge also serve to increase engine output. Due
to the large intake cross-sections, the throttle butterfly housings feature
special, progressively-acting kinematic control, the rider's commands in
calling up engine power being delivered to the throttle butterflies not on a
linear curve, but rather with a variable transmission ratio.
This sophisticated and well-conceived system ensures a harmonious flow
of power together with superior muscle and pulling force immediately when the
rider turns the gas handle to full load at low engine speeds.
It goes without saying that the machine's electronic intake manifold injection,
together with the engine management and exhaust manifolds, is specially
tailored to these modified flow conditions, the interior diameter of the
exhaust gas manifolds being increased by 5 millimetres or almost 0.20'' to
50 millimetres or 1.97'' on the new R 1200 S.
Despite its sporting character, the high-performance flat-twin power unit
offers the same running smoothness as the existing models in the R 1200 Series
-
a particular feature attributable, not least, to the balance shaft. The
dog-shift six-speed gearbox weighing just 13 kilos or not quite 29 lb as well
as lightweight shaft drive have already proven their qualities on the new Boxer
generation and are now being carried over without requiring any modifications
to the R 1200 S.
Refined frame.
Another proven concept is the multi-dimensional frame structure on the
R models integrating the engine into the chassis and suspension as a
load-bearing element: The R 1200 S features a three-piece frame specially
geared to the qualities and characteristics of this sports motorcycle.
The central and front sections of the tubular frame structure are made of
steel, while the rear frame bolted in place is made up of extra-light square
aluminium tubes. The advantages of this structure are not only low weight,
but also simple and low-cost repair of accident damage at the rear.
The passenger footrest supports also bolted on to the frame come off easily
within just a few moments, for example for riding the R 1200 S on a race track.
Stable Telelever with a steep steering head angle.
Steering precision is a particularly important requirement on a sports
motorcycle. But apart from an absolutely precise response to his steering
commands, the rider also expects clear feedback from the front wheel.
This is precisely why the Telelever front wheel suspension on the R 1200 S
comes with fixed tubes measuring 41 millimetres or 1.61'' in diameter and wheel
travel of 110 millimetres or 4.33''. Featuring longitudinal arms supported on a
specially matched spring strut, the Telelever does not require any maintenance
and reduces brake dive to a minimum.
The geometry of the suspension is new and has been specifically tailored to the
R 1200 S, even the basic data and configuration figures clearly highlighting
the agility and superior handling offered by this Sports Boxer on winding
roads, naturally in conjunction with low weight in road trim with a full tank
of just 213 kg or 470 lb: Measuring 66°, the steering head angle is 1° steeper
than on the former model, while front wheel castor is now just 87 millimetres
or 3.43'', instead of the former 100 millimetres or 3.94''. As a result, the
rider will hardly even notice that wheelbase is up from 1,478 to 1,487
millimetres (58.19 to 58.54''). What the sports rider will however notice and
appreciate immediately is that the R 1200 S allows him to lean over at an angle
2 per cent lower in bends than on the former model, enabling the rider to reach
an extreme position of up to 52°.
Spring strut with travel-dependent damping in support of the EVO Paralever.
The big advantages of the BMW Motorrad Paralever are well known and widely
acknowledged: Benefiting from its lifetime oil filling in the axle drive, the
lightweight driveshaft with single-arm wheel guidance requires absolutely
no maintenance and is hardly any heavier than a conventional swinging arm with
chain drive.
Made of cast aluminium, the entire structure rests on the frame of the
motorcycle via a modern gas-pressure spring strut with travel-dependent damping
(TDD) and offers 120 millimetres or 4.72'' spring travel.
Travel-dependent damping operates as a progressive system: The further the
spring strut moves in, the stronger the counteracting damper forces become. In
all, therefore, the system ensures a smooth and sensitive response to minor
bumps on the road as well as superior stability on bad or strongly ondulating
surfaces.
Light-alloy wheels in dynamic design with radial sports tyres.
The sweeping, dynamic design of the aluminium wheels has already attracted
attention on BMW Motorrad's sporting and dynamic K-models and is
now to be admired for the first time on the Boxer Series. Particularly the
stylish rear wheel is a genuine eye-catcher, the high-rising silencer allowing
a free, unobstructed view of the wheel.
The R 1200 S is also a genuine sportsman when it comes to wheel
dimensions: The 3.50 x 17-inch wheel at the front runs on a 120/70 ZR 17 radial
sports tyre with particularly good grip, while the 5.50 x 17-inch wheel
at the rear features a high-grip radial sports tyre measuring 180/55 ZR 17.
And as an option, the R 1200 S is available straight from the factory with
a six-inch rear wheel running on a 190-format tyre.
Sports brake system with ABS as an option.
The new BMW R 1200 S is an uncompromising performer also in its brake
technology: The front wheel comes with two brake discs measuring
320 millimetres/12.60'' in diameter and 4.5 millimetres/0.18'' in thickness,
and held in position when required by two four-piston swing callipers. This
brake system outperforms the brakes even the R 1100 S, which already were quite
outstanding with its brake discs measuring 305 millimetres or 12.01'' in
diameter and 5.0 millimetres/almost 0.20'' across.
The rear wheel, in turn, comes with a double-piston floating calliper acting on
a brake disc measuring 265 millimetres or 10.43'' in diameter.
Benefiting from brakes of this standard, even the sports rider out on a race
track can rely on smooth and consistent, precise brake response with operating
forces reduced to a minimum. Hydraulic control and superior operation
of the brake pistons is ensured by high-quality, steel-reinforced brake hoses.
Choosing an appropriate ABS anti-lock brake system, the engineers at
BMW Motorrad focused from the start on the sports-minded rider: The system used
on the R 1200 S is an upgraded two-channel ABS configuration
without an integral function or brake servo, excelling through low weight and
compact dimensions and thus adding just 1.5 kilos or 3.3 lb to the overall
weight of the machine.
This low weight is made possible by a newly designed, extremely compact
pressure modulator featuring linear-control intake valves for optimum brake
pressure at all times in the usual ABS control range, that is when applying the
brakes with the risk of the wheels locking. This superiority is ensured by
very fast and precise control intervals, the new control valves with their
infinitely variable cross-section also enhancing the feeling of smoothness for
the rider, who will feel only a minor pulse effect in the brake levers
A further advantage for the rider is the option to deactivate ABS when riding
on a race track.
BMW Motorrad's new ABS anti-lock brakes again come with an even wider range of
diagnostic functions, the wheel speed sensors, for example, automatically
supervising their distance from the sensor wheel and thus contributing to the
supreme standard of all-round safety offered by the system.
CAN-bus on-board network, cockpit with a wide range of rider
information, and electronic immobiliser featured as standard.
It almost goes without saying that BMW's new Sports Boxer comes with the
single-wire system (SWS) on-board electronics already featured on the R 1200
GS. Having already proven its merits a million times over in the automobile,
this superior technology offers a wide range of benefits: It reduces
the number and length of cables required, uses CAN-bus technology to connect
all control units, and in this way facilitates the process of diagnosing all
kinds of running conditions. A further advantage is that the system eliminates
the need for conventional melt-down fuses by automatically switching off the
component involved in the case of malfunction.
Using data provided by the single-wire system, the rider is able to retrieve
and call up lots of information via the Info-Flatscreen. As an example, the
digital display presents the gear currently in mesh, the amount of fuel left in
the tank, current oil temperature, the time of day, and the range remaining on
the
fuel still in the tank. And in presenting all this information with optimum
clarity, a photo-cell control unit even takes ambient light conditions into
account, automatically adjusting instrument light intensity to current
requirements.
Even the aficionado of analogue instruments will be thrilled at first sight by
the cockpit, two circular dials with white faces providing clear information on
the current speed of the machine and engine revolutions.
An electronic immobiliser is naturally standard on all BMW motorcycles as an
appropriate reflection of their high class and quality. So to the start the
engine the rider intentionally requires more than a key with the right
contours, since the chip integrated in the original BMW key must in all cases
first transmit the right code to the annular aerial on the combined steering
and ignition lock, thus enabling engine management to clear the engine for the
starting process. This technology is currently the safest and most reliable
system protecting
a vehicle from theft.
Body design - slender and athletic all in one.
Even at very first sight, BMW Motorrad's new Sports Boxer boasts an even more
slender and dynamic figure than its predecessor, while nevertheless
taking up the unmistakable design language of the R 1100 S. The front end of
the new machine is dominated by an asymmetric dual headlight featuring
reflectors with geometrically optimised free-shaped surfaces carried over from
the GS model. High-intensity H7 bulbs ensure bright illumination, and the cover
lens made of scratch-proof polycarbonate coating new in its structure and
material qualities harmonises perfectly with the BMW kidney grille
further down guiding the air flowing by straight to the engine oil cooler.
The sporting windscreen likewise comes with a scratch-proof surface coating and
is fitted in position in the upper section of the fairing by means of
spring brackets facilitating, for example, the subsequent assembly of a tinted
windscreen available as an option. A further advantage is that the fastening
points are no longer visible from outside, making the entire front section
smooth and clean in design, with all features and components fitting together
perfectly. And last but certainly not least, the direction indicators
integrated
in the rear-view mirrors also make an important contribution to this superior
style and good looks.
Yet another striking feature is the fairing support made of light pressure-cast
magnesium. Finished in Graphite Grey metallic paintwork and fastened in
position by aluminium bolts, this important component is an integral feature of
the overall design concept and may be admired not only by the rider sitting
on the machine, but also by an outside observer.
Featuring a new silencer and exhaust emission outlets placed beneath one
another, the rear end of the motorcycle is accentuated particularly in its
vertical look. The extra-large, voluminous muffler is positioned below the rear
fairing smoothly and attractively integrating the direction indicators into the
overall design. A further feature boasted right at the top is the new tail
light with no less than 18 light-emitting diodes comprising both the reversing
and brake lights operating in two different levels of brightness. Compared with
a conventional tail light cluster, the light-emitting diodes require only about
10-20 per cent of the usual level of energy, while at the same time
offering a much longer service life and significant safety benefits thanks to
their even faster response time.
Focusing on technical features, the aerodynamic qualities of BMW Motorrad's
Sports Boxer deserve particular mention, especially after being perfected
in the wind tunnel: With sporting performance naturally being one of the main
considerations in the development process, greater significance has been given
in this case to the lowest possible drag coefficient as opposed to enhanced
protection from wind and weather. But this does not mean that the carefully
designed, low-slung windscreen on the R 1200 S does not give
the rider efficient protection around his upper body, thus effectively reducing
wind forces at high speeds.
The new BMW 1200 S stands out not only through its technical features,
but also through superior all-round harmony in design. Indeed, seen from above
the distinctive waist of the new model is almost a bit sensual.
BMW offers the R 1200 S in no less than four different colours, each of which
gives the machine a particular, individual touch. Paintwork in Night Black
non-metallic, for example, focuses your view on the essential and conveys an
immediate feeling of sporting elegance, while White Aluminium matt
metallic highlights in particular the design language and lines of the R 1200
S. A particularly striking touch is ensured by Yellow non-metallic with a dark,
matt-metallic centre stripe stretching from the front end of the machine via
the fuel tank all the way to the seat.
And last but certainly not least, an especially outstanding colour is twin-tone
paintwork in Red non-metallic/Titanium Silver metallic, creating a new touch
time and again from different perspectives and visually integrating the red
seat into the overall colour concept of the motorcycle.
Ensuring a relaxed and sporting posture.
A sports motorcycle must allow the rider to lean forward in a dynamic, "fast"
position in order to benefit in full from his - or her - preferred style of
riding. Indeed, the shift in weight provided in this way generates an optimum
load on the front wheel when braking and entering a bend, and keeps the wheel
even better on the road when accelerating.
Despite these important considerations, the handlebar remains at exactly the
right height to avoid any undue loads or forces acting on the rider's wrists.
Seat height of 830 millimetres or 32.7'' and the well-conceived arrangement of
the rider's footrests guarantee a comfortable knee angle allowing the rider to
keep his knees firmly on the tank. A further advantage is that the rider will
find it easy to reach the ground with his feet, the seat particularly slender
at the
front keeping the overall distance from one foot to the other on the ground
to a mere 1,810 millimetres or 71.26''.
