2013 BMW S1000RR HP4, More Performance Super Sportbike

Eager to capitalize on the success of this year's premium brand and other sports Limited Edition BMW has its name-spec 'HP' (High Performance) at the S1000RR superbike. In addition to the exclusive 2013 BMW S1000RR HP4 provides superior performance and control.

The function of the electronics of the motorcycle is a large part of the packaging HP4. Is highlighted by the use of a semi-active suspension for a first sport bike production. Doubled, Dynamic Damping Control (DDC), the fork and shock absorber damping automatically while driving on the basis of data from sensors and control inputs of the driver.

In addition, the channels of the train and rebound can be adjusted electronically with one touch. Preload is manually adjusted but simple and easy access to the body of the shock button. Wedges are used to increase the clearance as a function of the geometry of the tire or the driver's preference. A classical types gypsy is placed on the right fork leg used for the setting.

On the Jerez circuit, the damping characteristics felt almost perfect for a driver in the fast lane calibrated. Both the fork and shock read thick precision and road conditions were controlled as each race moved into its components. When one end of the choke was greatly (shock) or braking load losses (area) was not sufficient to cause an excessive height of the chassis.

Although it is not the answer "feel every pebble in the road" of a well-tuned bike still performed at a high level, even in the more self-confidence control inputs during the session of the afternoon with the installation fabulous Pirelli Diablo Supercorsa running smoothly. The real test will be, but how the system reacts on bumpy, stop-and-go-American race track in Jerez, it performs flawlessly.

The power mode control motor and also benefit from a new program. As a standard 2013 BMW S1000RR HP4 uses the four energy / gas unique cards: Rain, Sport, Race and Slick (for use with the least tread racing tires). Rain mode now provides access to the full power of the engine, but with a smoother distribution of torque to traction on wet surfaces or limited soil use. The remaining three parameters are all. Using fresh maps for precise engine response and delivery of linearly through its 14,200 rpm speed range performance In addition, the torque curve of the engine 6000-9750 rpm has been increased for better acceleration.

Although the reaction of the accelerator pedal and the fuel supply to the engine was never a problem with the standard model '12, the new HP4 provides finer than before. Flat out, it's smooth, linear powerband feeling we experienced S1000RR. It's crazy, because the bike is almost slower due to its less aggressive high-end hit. But it's not always on the bike wheelies performance in the first four reports. Power seemed beefier midrange, which certainly helps the bike fast corners where the engine is not running on his grand 10th

Calibration of Dynamic Traction Control (DTC) is also modified to receive on the basis of data from the BMW World Superbike team. Revised parameters reduce accuracy of the motor with excessive wheel spin torque is detected. In addition, the activation of the DTC provides a ready-setting (14 lanes and fly) with the button on the left side of the handlebar.

The control parameters Wheelie also been tweaked to provide a more flexible and more accurate response if the power wheelies are detected. The electronic launch control and are now also equipped with velocity template (aka Quickshifter e) Shift. ABS has finally re-encoded Racing system with the parameters from the participation of the Bavarian brand in the national series race IDM Superbike derived. The device's screen gets a new police inside the analog speedometer styles and additional features for the new launch control, DDC and adjustments DTC Slick mode. The new menus are intuitive and easy to reach.

Just like the '12 machine BMW has managed to refine the operation of the DTC on the  BMW S1000RR HP4. It is more accurate if excessive wheel slip is determined and if the engine torque modulated discretely. The ability to refine DTC in Slick mode is also great advantage that the driver to compensate for tire wear, track temperature and allows fatigue.

Perhaps the biggest improvement is the operation of the wheelie control. As before BMW did a great job of detecting a rising front, but where the old power cutoff system when it suddenly snapped the front wheel on the ground of the new electronic system, set the front wheel on the ground smooth. This allows the driver noticed out of the corner at full throttle without bury the bike loop for power wheelies worry.

For use in road racing or drag racing HP4 starts now has a launch control. The module system, the engine torque in first gear to maximize acceleration of a death sentence. Compared to other systems, the HP4 is easy to use, with the rider holding the start button for a few seconds when the engine is at a standstill. The scoreboard shows that the mode has been activated. Remove the shift lever into first gear and the accelerator and electronics keep the engine speed at 8,000 rpm. Run the clutch quickly and the bike to move forward, clean, without the worry of the engine bogging down too much, or wear out the clutch prematurely. Overall, the system is working very well, but the engine has not easily sink. Better to manually start an experienced driver, but it will be difficult to match the consistency offered by the electronic system.

With the exception of fresh ECU programming and engine / fuel injection maps 999cc liquid-cooled inline four-cylinder engine, the HP4 is identical to the first-class entity in the S1000RR. However, the HP4 factory is equipped with a full Akrapovic titanium exhaust system. The tube shaved more than 10 pounds of the bearing configuration, even with the installation of a noise control valve and catalyst. As always, the S1000RR psychotic impressive performance of his engine. But as already mentioned, the biggest feature how sweet it is at all speeds and the additional midrange below 10,000 rpm. Do not worry if the engine is still a healthy dose of character for a four-cylinder in-line engine, and it's still all the right noises when you are whining about the distance you hover with the speedometer needle near the red zone .

BMW has some subtle but important changes to the 2012 S1000RR frame and fork bridges in an effort to improve their handling skills. The brand continues to refine the propeller lighter wheels towards the HP4 by installing a pair of seven-spoke forged aluminum anodized black. Note also the use of a medium lighter sprocket. This battery with smaller casts further six pounds from the weight of the bike.

Apart from the electronics is one of the most important areas for improvement. The lighter wheels do wonders to change in relation to the steering forces with the HP4 power, much more responsive direction despite the new slightly wider profile Pirelli Diablo Supercorsa SP rear tire (200/55-17). There is so much more agile as a runner with the S1000RR need time to acclimate quickly as it maneuvers, especially mid-corner.

The older two-part brake calipers and Brembo monobloc calipers generation for robust style floating discs (320mm diameter) with a low friction material tailored to the BMW spec pads replaced along with a new set of nine buttons. The standard S1000RR has never been available in the off state, but new brakes facilitate feelings and consistency are you in round 1 or 10 In relation to the operation of the ABS, we were not revealed to actively activate at a fairly quick pace as the discrete system is the most runners on the track.

To further emphasize the pedigree of road HP4 from tourism accommodation and adds a lower fascia that extends around the rear wheel it. Not only does it look slimmer, it improves aerodynamics, too. LED indicators are also included, such as a windshield is tinted. Each bike has a special HP Racing Blue Metallic / Light colors. And for those who want something more exotic looking, the competition package adds body parts carbon fiber rims Racing blue anodized metal and a sticker set, the bike look like World Superbikes making plant. It is also equipped with racing style footrests are adjustable rotor brake and clutch levers are turning into less likely to be damaged in an accident.

In fact, the formula improves 2013 BMW S1000RR HP4 function around the circuit. But the look, as we are by the way is much more refined thrilled a motorcycle is like a package. Synergy powertrain, chassis and electronics allows the rider to ride at a pace that they might not be as comfortable on a different brand. And that is what distinguishes the HP4 beyond anything else on the market. As technology and the astronomically high performance of this machine is capable of its going to be an absolute steal if BMW is able to sell it for anywhere near its estimated $ 25,000 in the United States.
