The first sportbike with real aerodynamic downforce? We'd like to see just how much downforce the front fairing and rear seat fairing with side wings generate in a windtunnel at high speed.

BMW's First Superbike Hits the Streets
BMW S 1000 RR Production Bike
Monza, Italy , May 5h, 2009 - BMW introduced their new BMW S 1000 RR today on the legendary Monza Racing Circuit, BMW Motorrad is for the first time launching an absolutely innovative supersports with a straight-four power unit. With this world debut, BMW Motorrad is indeed establishing a true milestone in the world of sports machines, combining 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.
The decision to present this unique performer in Monza was by no means a coincidence. For since the beginning of this year Team BMW Motorrad Motorsport has been playing an active role in the World Superbike Championship, 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. And obviously the Royal Park in Monza is the ideal place for a presentation of this calibre.
Maximum performance and riding dynamics.
The consistent concept of the S 1000 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 like in a BMW Formula 1
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.
Following the example of BMW ’s Formula 1 engines, 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 muffler) 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 ABS.
The new S 1000 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 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.
