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
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 in
diameter and wheel travel of 110 millimetres. 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: Measuring 66°, the steering head angle is 1°
steeper than on the former model, while front wheel castor is now
just 87 mm, instead of the former 100 mm. As a result, the rider
will hardly even notice that wheelbase is up from 1,478 to 1,487mm.
What the sports rider will notice - and appreciate immediately - is
that the R 1200 S allows a lean 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 mm of spring
travel.
Travel-dependent damping operates as a progressive system. The
further the spring strut moves in, the stronger the counteracting
damper forces become. Thus 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.
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. 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 sports machine when it comes to
wheel dimensions: The 3.50x17-inch wheel at the front runs a 120/70
ZR17 radial sports tyre, while the 5.50x17-inch wheel at the rear
features a high-grip radial sports tyre measuring 180/55 ZR17. And
as an option, the R 1200 S is available straight from the factory
with a six-inch rear wheel running on a 190-profile 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 mm in diameter and 4.5 mm in thickness, and held in
position when required by two four-piston swing callipers. This
brake system outperforms the brakes on the R 1100S, with its brake
305mm discs.
The rear wheel, in turn, comes with a double-piston floating
calliper acting on a 265 mm brake disc.
Benefiting from brakes of this standard, even the sports rider
out on a racetrack 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 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 the ABS when riding on a racetrack.
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.
BMW’s new sports Boxer comes with the single-wire system
(SWS) on-board electronics already featured on the R 1200GS. Having
already proven its merits in the car industry, 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 riding distance
available on the remaining fuel. 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 standard, so to start the engine
the rider requires more than a key with just 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.
