Concept and Features
Introducing the new R 1200 S -- BMW Motorcycles 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 Motorcycles 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 super-sports. 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 optimized 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 Has 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 millimeters or 0.20´´ to 52 millimeters 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
millimeters or almost 0.20´´ to
50 millimeters 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 aluminum 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 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 millimeters or 1.61´´ in diameter and wheel
travel of 110 millimeters 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 millimeters or 3.43´´,
instead of the former 100 millimeters or 3.94´´.
As a
result, the rider will hardly even notice that wheelbase
is up from 1,478 to 1,487 millimeters (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°.

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 aluminum, 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
millimeters 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 undulating surfaces.
Wheels and Tires
The sweeping, dynamic design of the aluminum 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 tire with particularly
good grip, while the 5.50 x 17-inch wheel
at the rear features a high-grip radial sports tire
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 tire.
ABS Brakes Optional
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 millimeters/12.60´´ in diameter and 4.5 millimeters/0.18´´
in thickness, and held in position when required by two
four-piston swing calipers.
This brake system
outperforms the brakes even the R 1100 S, which already
were quite outstanding with its brake discs measuring
305 millimeters or 12.01´´ in
diameter and 5.0 millimeters/almost 0.20´´ across.
The rear wheel, in turn, comes with a double-piston
floating caliper acting on a brake disc measuring 265
millimeters 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
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-flat screen. 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.

Design
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 optimized 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 harmonizes 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 aluminum 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
colors, 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.
Riding Position
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 millimeters 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 millimeters or 71.26´´.
