BMW HP4 RACE.
The HP4 RACE is more than the sum of its parts. This bike is pure emotion. From the development right up to the racetrack, passion is what has made this race bike what it is. An innovation driver, designed to push the limits. The HP bike is the first motorcycle in the world to offer a fully carbon frame and fully carbon wheels. With 158 kW (215 HP) of power, it weighs just 146 kilos (dry weight). A handmade dream come true for 750 enthusiasts.
Pure performance 750 times over
The HP4 RACE is a masterpiece of engineering prowess. Each and every one of the 750 limited-edition racing machines was handmade by our specialists and fitted with a numbered sticker. For those who have no limits and always go further. There are only a few like this. More precisely: seven hundred and fifty.
Fully carbon - all or nothing
New benchmark in lightweight construction.
The frame of the HP4 RACE is made of endless carbon fibre and is a continuous component from the steering head to the swing arm pivot. Compared to the standard frame, it saves a full four kilos in weight. For the BMW HP4 RACE's carbon technology, it's not about how it looks, but rather its characteristics. They facilitate the precalculation and incorporation of function-dependent torsion and rigidity. As rigid as aluminium, as hard as steel. All advantages of the carbon material were fully exhausted on the wheels. They remain particularly flexible.
The design of the HP4 Race
Perfection right down to the smallest detail.
Developed for the racetrack through and through, the HP4 RACE has a self-supporting carbon front that practically devours the headwind with its aggressive splitface with the ram air behind. The dome-shaped windscreen offers riders optimal protection and keeps them in the streamline. The perfect interplay between paintwork and carbon material makes the HP4 RACE an absolute highlight when it can be admired at a standstill. A new era is dawning for colour too. With the HP4 RACE, we present the new HP motorsport colours Light white uni uni / Racing blue metallic / Racing red uni uni.
Four-cylinder four-stroke in-line engine
Built by hand. Configured for maximum performance.
Built by hand. Configured for maximum performance.
Made by hand in Berlin, the HP4 RACE engine is a further development of the engine from the long-distance WM and the World SBK. It produces 158 kW (215 HP) and the maximum rotational speed was increased to 14,500 rpm. The maximum torque of 120 Nm is at 10,000 rpm. The first service, including an oil change, is carried out after the engine has been run in and recorded on the test stand by our specialists. The engine is endoscoped and the control times and valve clearance are adjusted. Meaning that the HP4 RACE is ready to reach its full potential on the racetrack right from delivery.
Experience the sound of the HP4 Race
The highlights of the HP4 RACE
Power and perfection. The engine housing was "HIPed", the smallest air pockets were eliminated from each individual part under overpressure. The light and high-strength motorsport steel connecting rods are paired to 0.5 g and move in the finely balanced crankshaft. The four pistons are paired and optimised for withstanding the increased rotational speeds and loads. The maximum regulated oil pressure of the oil pump was reduced from 6 to 5 bar and, in combination with thin-bodied 0W40 oil, generates significantly less power loss. Each HP4 RACE Motor engine is tolerated to firing capacity. After retracting the engine, the combustion chamber is endoscoped in order to detect any collisions of the piston on the combustion chamber roof. The engine retracted on the test stand is fully resilient right from the word go.
Brake performance at the top level. The Brembo GP 4 PR brake calliper is well-known from Moto GP. It encompasses a T-floated racing brake disc with a diameter of 320 mm. With a thickness of 6.75 mm, it can withstand the highest loads. The monobloc brake calliper is particularly temperature resistant and the reduced-friction titanium pistons round off the brake line. The brake callipers are fitted with Brembo /04 racing pads.
Footrests + shift assistant
The 6-speed EVO gearbox has shortened shift travels and includes a secondary transmission. The gearbox is controlled via the HP RACE shift Shift assistant Assistant proPro. The rider receives clear feedback with each gearshift due to the lack of a spring actuator. As is usually the case in racing sport, part switching is eliminated and the first gear is located at the top. Gears 2-6 are shifted downwards. If necessary, the gearshift mechanism can be converted to street format. The wheelie control and the maximum engine torque are attuned to the respective riding modes WET, INT, DRY1, DRY2. The pit lane limiter is ready for use when the first gear is selected. When at a standstill, the launch control also starts automatically. This ensures that riders are able to focus their full concentration on the race start.
Steering head + fork bridge
Every HP4 RACE has its own consecutively numbered carbon plate that is countersunk into the fork bridge. The functional chassis of the HP4 RACE can be adjusted for any type of racetrack. Using the variable offset adjustment, riders can adjust the factory settings of 30 mm with depositor stones in 26-32 mm and 30-28 mm. The steering head angle is 0.5° flatter than on the standard model at 65.5°. It can be adjusted from +0.5° to +1°. Thanks to the settings, the an after-run of 95-112 mm can be achieved.
A milled aluminium button panel makes all important riding settings available with particular operating accuracy. On the left, the dashboard display screens can be switched and all DTC and EBR settings carried out. Both the setting for the riding modes ( WET - INT - DRY1 - DRY2 ), the start button and pit limiter and the kill switch are located on the right hand side.
Seat + ergonomics
Optimal ergonomics for every rider. The standard seat height is 831 mm, the lowest seat adjustment (-15 mm) is 816 mm and the highest seat adjustment (+15 mm) is 846 mm. Furthermore, the milled footrest system has 8 different settings. The handlebar tapering can also be adjusted by 15°.
DTC + EBR
The dynamic traction control gets its information from the re-positioned angular rate sensor. The traction can be adjusted from +7 to -7 and four riding modes are available to choose from. The modes: WET - INT - DRY1 - DRY2 vary in terms of the progressive mapping of the gears, the relative maximum torque and the specification of the wheelie control. Together with the EBR (engine brake), riders can influence the braking and acceleration characteristics and optimally adjust to the conditions of the racetrack.
The carbon fibre rims and the specific design of the wheels save an additional 1540 g compared to the forged wheels. The significantly reduced dimensions of the wheels, especially the circumference, are particularly noticeable with each change of direction and when braking. For the material connections, an optimal positive locking is achieved by shrinking and pressing in add-on parts such as the chain strap mounting made of aluminium. This enables insert solutions to be completely avoided and the stability to be increased even more.
A dry weight of 146 kilos (DIN empty 171 kg) is hard work. Each component was weight-optimised or, if it is not needed, discarded. It was checked right down to the smallest detail where a gram can be saved and the function kept intact or whether it might even be able to be improved. For instance, titanium screws are used for the engine and frame. In sizes 6, 8 and 10, they not only save weight, but also save on the required tools.
