BMW’s awesome S1000RR, the overall winner of our “Class of 2012” superbike comparison and our choice for Sportbike of the Year, wasn’t exactly lacking performance. That didn’t stop the German manufacturer from developing this limited-production, HP4 edition that delivers even more high-speed potency. The HP4 uses the same 999cc, 193-horsepower inline four as the base S1000RR, recalibrated to boost torque between 6000 and 9750 rpm. An all-titanium Akrapovic exhaust cuts 9.9 pounds, and forged-aluminum, 7-spoke wheels slash another 5.3 lbs. Dry weight is claimed at just 372 lbs. (with Race ABS), which singles out the HP4 as the lightest four-cylinder literbike ever, according to BMW.
The big news here, however, is the suspension. The HP4 debuts BMW’s revolutionary Dynamic Damping Control (DDC) active suspension system, making it the first production motorcycle to automatically alter its damping characteristics in direct response to changing riding conditions. Electronically actuated valving that instantly and constantly adjusts compression and rebound damping should result in theoretically perfect suspension action at all times, capable of absorbing big hits without compromising small-bump compliance or high-speed stability.
Dynamic Damping Control is a quantum leap ahead of BMW’s existing Electronic Suspension Adjustment (ESA), or even Ducati’s Öhlins-built electronic suspension. Unlike those systems, which alter damping (and spring preload, in the case of ESA) only when the rider pushes a button, DDC automatically adjusts damping in response to changing riding conditions without any rider input. Adapted from existing BMW automotive technology, DDC utilizes an electronic valve with a variable piston ring to alter the flow of damping fluid in milliseconds, instantly optimizing damping response. Preload is still adjusted manually, using conventional tools.
DDC combines input from spring-travel sensors with data on road speed, lean angle, throttle position and more, then adjusts damping response according to proprietary suspension action “maps.” Baseline settings are 15-level-adjustable to suit various rider weights and riding styles. From there, DDC sensitivity varies in accordance with the riding modes: settings in Rain and Sport modes blend performance and comfort; Race and Slick modes prescribe tighter settings that favor crystal-clear chassis feedback.
BMW made numerous other improvements to the S1000RR’s already comprehensive suite of electronic rider aids, further optimizing the Dynamic Traction Control (DTC) and switchable Race ABS systems for improved functionality. The four distinct ride modes remain—Rain, Sport, Race and Slick—each cueing DDC, DTC and ABS settings specifically tailored for the specified riding conditions. Unlike the base S1000RR that’s programmed to cut power and blunt throttle response in Rain and Sport modes, however, the HP4 delivers full power and the same aggressive throttle curve in all four modes, for more consistent racetrack performance.
The HP4 finally offers tunable traction control, addressing our biggest complaint about the standard S1000RR that only provides four preset traction-control levels—one for each ride mode. HP4 owners can choose among 15 levels of traction-control sensitivity (in Slick mode only), adjustable on-the-fly using a paddle on the left switchgear, to fine-tune TC intervention according to rider preference or changing conditions. The Slick-mode ABS parameters have also been refined to allow even more aggressive braking, without sacrificing the security of anti-lock brakes. Lastly, an all-new launch control system actively limits torque to eliminate wheelspin and wheelies to enable the most efficient race launches possible.
An all-new dash incorporates additional screens for DDC set-up, DTC adjustment and launch-control activation. BMW’s electronic “shift assistant,” which cuts fuel and spark to allow instant, full-throttle, clutchless upshifts, is standard equipment, as are heated grips, too! No word yet on HP4 pricing, but we anticipate it will be much higher than a fully optioned S1000RR that sells for $16,995. Expect the HP4 MSRP to be closer to the $23,995 Ducati 1199S Panigale, which features electronically adjustable—but not active—suspension.

Also from CycleNews:
BMW has introduced its HP4, the company's first four-cylinder in the HP family and - with a dry weight of 373 pounds, including ABS - the HP4 is five pounds lighter than the S 1000 RR that it's based on.
Weighing just 439 pounds with a 90 percent full fuel tank, BMW claims the HP4 is the lightest four-cylinder supersports bike in the 1000cc class. The HP4 joins the boxer model HP2 Enduro, HP2 Megamoto and HP2 Sport in the HP (as in High Performance) family that started in 2005.
The new HP4 gets what BMW calls a first for production motorcycles: Dynamic Damping Control (DDC). The DDC is a semi-active suspension system that changes the front and rear damping based on the mode selected, lean angle and speed.
In addition to the DDC, the HP4 gets a more developed and refined Race ABS system that works in conjunction with Brembo monoblock brakes. The ABS has four different modes for wet surfaces (Rain), roads (Sport), racetrack with DOT tires (Race) and racetrack with slicks (Slick). In "Slick" mode, a new IDM setting (based on experience gained from racing in the Germany Championship) with "refined regulation impulses now gives the skilled rider the option of maximum possible deceleration." The Slick mode features an additional adjustment range of minus 7 to plus 7 and it's all controlled via a paddle on the left handlebar.
The HP4 is also the first BMW motorcycle to have a Launch Control function which provides active support for the rider in "Slick" mode to achieve maximum acceleration from standing - for example on race starts. The system limits torque so the rider basically controls acceleration by the clutch and not the throttle. The system also has wheelie control.
The HP4 also has a quickshifter (the shift assistant) so you can bang upshifts on the racetrack.
A lot of the weight loss comes via new seven-spoke wheels made from lighter forged alloy and a lighter sprocket carrier. The exhaust system is made entirely of titanium with a weight savings of 9.9 pounds over the S 1000 RR. The new exhaust system has a resonance pipe between cylinders two and three, a controlled acoustic valve and a closed-loop catalytic converter. BMW says the torque curve has been improved thanks to the new system.
Unlike the S 1000 RR, the inline four-cylinder engine in the HP4 provides the full output of 193 horsepower at 13,000 rpm in all modes - "Rain," "Sport," "Race" and "Slick" - with an identical throttle curve.
A "Competition Package" is also available for the HP4, which features carbon parts - including a long, closed HP engine spoiler in carbon. It also features an adjustable HP rider footpeg system, folding HP brake and clutch levers, wheels finished in Racing Blue Metallic and a factory sponsor sticker kit provide additional enhancement of the new HP4.
Here's BMW's breakdown of the technical highlights of the new HP4:
• Fork bridge with engraved number and HP4 logo.
• Lightest 1000 supersports bike with four cylinders: 439 lbs (199 kg)
(90% DIN unladen weight).
• Innovative suspension with Dynamic Damping Control (DDC).
• Race ABS with IDM setting.
• Dynamic Traction Control (DTC) with fine tune adjustment in "Slick" mode.
• Launch Control.
• Adapted wheelie detection.
• New rear wheel tires, 200/55 ZR 17.
• Shift assistant as standard equipment.
• Light titanium exhaust system with controlled acoustic valve and resonance pipe.
• Forged light alloy wheels, anodized in black.
• Radial monoblock brake calipers by Brembo with special brake pads.
• 9x floating brake discs at front.
• Extended, dual-section engine spoiler.
• Seat in monoposto look with passenger seat cover.
• Lighter 7 Ah battery.
• Performance-oriented engine set-up.
• Increased torque in the medium engine speed range.
And The Competition Package:
• Long, closed engine spoiler made of carbon.
• Sponsor sticker kit included.
• Wheels in Racing Blue Metallic.
• HP Carbon badge carrier.
• HP Carbon tank cover.
• HP brake lever, hinged.
• HP clutch lever, hinged.
• HP rider footrest system, adjustable.
