2011 BMW S 1000 RR
  
  

The new BMW S 1000 RR is a highly innovative
straight-four supersports motorcycle from BMW Motorrad
now making its world debut.
This true milestone in the world of
sports machines combines engine output of 142 kW (193
hp) with overall weight of just 204 kg (450 lb) including
fuel (183 kg/403.5 lb dry weight, 206.5 kg/455.3 lb
overall with Race ABS).
Specifications of this calibre make
this supersports machine not only an absolute highlight
in terms of its power-to-weight ratio and performance,
but also, equipped with Race ABS and DTC Dynamic Traction
Control, a new benchmark in terms of riding dynamics,
safety and innovation.
Team BMW Motorrad Motorsport has been
playing an active role in the World Superbike Championship
since the beginning of the 2009 racing season, the
new S 1000 RR setting the foundation for the production-based
racing machines ridden by BMW Motorrad’s two
works riders Troy Corser and Ruben Xaus.
The Challenge for BMW Motorrad.
To successfully enter the World Championship
with a Superbike today, a manufacturer needs a production
model with the right kind of overall concept consistently
applied in all areas. The essential factors, therefore,
are supreme power, a wide range of engine speed, fast
revving capacity also over a long period, optimum
chassis stiffness, and perfect set-up of the engine.
Other features absolutely essential
more than ever particularly in the top league of supersports
motorcycles are simple and straightforward rideability,
lightfooted handling, absolutely outstanding all-round
performance as well as safety features such as rider
assistance systems like ABS and traction control giving
the customer precisely what he needs.
Developing the RR, BMW Motorrad has
entered completely new, unchartered terrain. Clearly,
this meant a huge range of new challenges and responsibilities
for the entire Development Team, but also gave the
Team enormous motivation in seeking to set new standards.
The specific targets in developing
the S 1000 RR were therefore clear:
- To achieve output and performance of the highest
standard.
- To make the suspension absolutely stable, with
top handling and supreme traction.
- To give the new machine that unmistakable, dynamic
design of BMW Motorrad.
- To reduce the weight of the motorcycle to an
absolute minimum.
- To ensure top quality typical of BMW .
Unique against the competition.
Over the years and decades, the principle of combining
a straight-four power unit with an aluminium bridge
frame has been consistently developed and has become
the dominating technical concept particularly in the
supersports segment. The reason, quite simply, is
that a motorcycle of this kind offers significant
benefi ts in terms of riding dynamics, long-distance
endurance, and straightforward production.
Precisely this is why the new S 1000 RR also applies
this concept with its proven fortes and advantages.
But even while the S 1000 RR, in its concept teaming
up a straight-four power unit and an aluminium bridge
frame, may appear at fi rst sight to have similarities
with some competitors, the Development Team at BMW
Motorrad has succeeded in enhancing the existing status
of this concept in virtually every respect.
As a result, the S 1000 RR offers not only a wide
range of USPs in terms of technology, performance,
and design, but also, through its particularly compact
overall layout, clearly demonstrates the high school
of European engineering in the supersports four-cylinder
segment.
Maximum performance and riding dynamics.
The consistent concept of the RR supersports is
borne out in particular by the truly fascinating,
innovative high-performance technology and incomparable
riding dynamics of this new machine. The result is
an exceptional combination of supreme riding precision
and agility, on the one hand, with unparalleled
engine power and performance, on the other, providing
an overall package truly unique in the market.
Never before has a BMW motorcycle been conceived
and built more consistently for supersports riding
in terms of its concept and overall construction.
But at the same time the new S 1000 RR retains many
of the virtues so typical of every BMW to this day:
Extreme sportiness and riding dynamics combined with
supreme everyday riding qualities, playful handling
together with supreme riding stability, outstanding
performance combined with unparalleled active safety,
as well as dynamic, unmistakable design in conjunction
with optimum ergonomics and aerodynamics.
Free choice of engine characteristics as well as
Race ABS and DTC Dynamic Traction Control
The new S 1000 RR also excels through features and
qualities typical of BMW such as a long running life,
superior quality of production and optimum environmental
compatibility thanks to the use of the most advanced
exhaust management with two fully controlled three-way
catalytic converters also able to fulfil future standards
and requirements.
Active safety when braking is signifi cantly enhanced
by Race ABS developed especially for the S 1000 RR
as a genuine supersports and available as an option
straight from the factory. A further most signifi
cant feature likewise contributing to active safety
of the highest standard is DTC Dynamic Traction Control
also available as an option and masterminded electronically
for supreme precision and practical value.
Facing various riding conditions such as wet roads
(“Rain”), regular road conditions (“Sport”),
a race track with supersport tyres (“Race”),
or a race track with slicks (“Slick”),
the rider also has the choice of various engine characteristics
and set-ups available at the touch of a button. And
last but not least, Race ABS
and Dynamic Traction Control are combined with the
respective riding modes and coordinated with one another
to ensure a supreme standard of performance and safety
all in one.
Valve drive for maximum engine speeds, with
single cam followers and titanium valves.
The primary objective in developing the new S 1000
RR was to create a supersports with supreme engine
power combined with optimum rideability for the highest
conceivable standard of all-round performance.
The water-cooled four-cylinder inline power unit
chosen to provide these qualities is brand-new from
the ground up, developing maximum output of 142 kW
(193 hp) at 13,000 rpm and revving up to a maximum
speed of 14,200 rpm. Maximum torque of 112 Nm (82.5
lb-ft), in turn, comes at 9,750 rpm.
The two intake and exhaust valves per cylinder made
of extra-light titanium are operated by very small
and equally light single cam followers. In conjunction
with the short sprocket driving the camshaft via an
intermediate gear, this ensures supreme revving qualities
at the highest speeds as well as exact maintenance
of
valve timing combined with very compact dimensions.
The use of extremely small and light cam followers
furthermore gives the engineer greater freedom in
choosing the ideal valve lift curves and, accordingly,
in selecting optimum performance characteristics on
both road and track. All engine components are particularly
compact and light, limiting weight of the overall
engine without ancillaries to 59.8 kg (131.8 lb) and
keeping the entire power unit very slim and slender.
Innovative exhaust system with interference
pipe butterflies for optimum power and performance.
Made completely of stainless steel, the exhaust
system featured by the S 1000 RR is designed consistently
for optimum power and performance. It works according
to the 4-in-2-in-1 principle with four individual
manifolds of equal length fi rst merging into two
pipes beneath the engine block and then extending
into a large-volume pre-silencer. From there the exhaust
emissions flow through a very short and dynamically
designed rear-end silencer to the outside.
A homogeneous power and torque curve ensuring optimum
rideability is acknowledged as the requirement for
sporting performance on the road and fast lap times
on the track. Precisely this is why the exhaust system
featured on the S 1000 RR comes with two fully controlled
interference pipe butterflies housed in two connection
pipes for the two outer and two inner manifolds, in
the immediate vicinity of the exhaust ducts. As a
function of various parameters such as engine speed
and the position of the throttle butterfly, an adjuster
opens or closes these flaps, allowing exhaust gas
to flow freely between the two manifolds or, respectively,
interrupting the flow of gas. This coordinates the
sequence of oscillations in the exhaust gas mass flow,
reducing exhaust gas counter-pressure at the decisive
point (like on a racing muffl er) and increasing
the cylinder charge accordingly.
This factor alone makes a signifi cant contribution
to the very high standard of homogenous overall performance
offered by the S 1000 RR.
Lightest supersports with Race ABS.
The new RR offers the highest standard of technology
also on its suspension and running gear. Weighing
just 206.5 kg or 455.3 lb in road trim and with a
full tank, BMW ’s new supersports is by far
the lightest machine of its calibre displacing 999
cc and featuring Race ABS brakes.
One of the features that ensures this light weight
is the aluminium bridge frame integrating the engine
tilted to the front at an angle of 32° as a loadbearing
element for optimum torsional stiffness on minimum
weight. The front wheel runs on an upside-down fork
with a fi xed tube measuring an ample 46 milli metres
or 1.81" in diameter, while a torsionally stiff
swing arm made of aluminium holds the rear wheel in
position.
The spring and damping action required is provided
by a central spring strut pivoting on a guide lever.
The rear frame section of the S 1000 RR is a welded
light-alloy structure belted to the mainframe, combining
low weight with superior stability and a high standard
of robust strength particularly important to riders
and teams on the race track.
Putting the rider right in the centre.
The rider’s seating position leaning forward
towards the front wheel for an active style of riding
is simply ideal for the sporting rider with his particularly
dynamic style.
Developing the S 1000 RR, BMW Motorrad has given
particular attention to the superior ergonomics of
the machine, providing ideal qualities for both small
and tall riders and therefore focusing consistently
on the rider’s individual requirements.
The tank section is as slender as on a 600-cc machine,
giving the rider the assurance of excellent control
and handling at all times.
In the process of developing the S 1000 RR, BMW
Motorrad focused not only on a lightweight structure,
but also on minimum, highly compact dimensions as
an absolutely essential requirement.
To give the S 1000 RR an extremely slender front
silhouette but at the same time to ensure a highly
effi cient fl ow of cooling air, the engineers at
BMW Motorrad had to show all their skill, since, with
cylinder bore measuring 80 millimetres or 3.15”,
the power unit of the RR has the largest cylinder
bore in this segment with a correspondingly wide cylinder
head.
Technical challenges of this kind as well as a development
period of just four years made the S 1000 RR the ideal
project for consistent, all-out use of CAD (Computer-Aided
Design) technology as well as the most advanced calculation
methods, for example for the machine’s aerodynamics.
As the bottom line, the S 1000 RR is the absolutely
ideal motorcycle for the customers of BMW Motorrad
looking for new, unprecedented standards and qualities
in the supersports segment.
