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 215 hp (158 kW), it weighs just 322 lbs (dry weight). A handmade dream come true for enthusiasts.
The HP4 RACE is a masterpiece of engineering prowess. Each and every one of the limited-edition racing machines was handmade by our specialists and fitted with a numbered plaque. This is for those who have no limits and always go further. We only produce this kind of concentrated passion for those who share it. This is reserved for frontier crossers whose requirements are not only satisfied by the HP4 RACE, but have to redefine their requirements. 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 seamless carbon fiber and is a continuous component from the steering head to the swing arm pivot. Compared to the standard frame, it saves almost 9 pounds in weight. It’s not about the looks, rather, its characteristics when it comes to the BMW HP4 RACE's carbon technology. The designers facilitated pre-calculation and incorporated function-dependent torsion and rigidity. As rigid as aluminum, as hard as steel. All advantages of the carbon material were fully utilized on the wheels, including their flexibility.
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 is a highlight of the HP4 RACE, especially when it is at a standstill. A new era is dawning for color too. With the HP4 RACE, we present the new HP motorsport colors Light White / Racing Blue Metallic / Racing Red.
Four-cylinder four-stroke in-line engine
Built by hand. Configured for maximum performance.
Built by hand. Configured for maximum performance.
Built by hand in Berlin, the HP4 RACE engine is an enhanced version of the engine from the long-distance WM and the World SBK. It produces 215 hp (158 kW) and the maximum rotational speed was increased to 14,500 rpm. The maximum torque of 88 lb-ft 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.

The highlights of the HP4 RACE
Power and perfection. The engine housing was treated with hot isostatic pressing (HIP), 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 optimized 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 engine is engineered to strict tolerances for maximum power capacity. After fully testing the engine, the combustion chamber is endoscoped in order to inspect the combustion chamber for any imperfections.. Once the engine has passed its rigorous examination on the test stand, its full potential can be realized.
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 Assist Pro
The 6-speed EVO gearbox has shortened shift travels and includes a secondary transmission. The gearbox is controlled via the HP RACE Shift Assist Pro. The rider receives clear feedback with each gearshift due to the lack of a spring actuator. As is usually the case in racing sport, the first gear is located at the top, and gears 2 through 6 are engaged by moving the shift lever downwards. The wheelie control and the maximum engine torque are tuned 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, Castor values of 95-112 mm can be achieved.
A milled aluminum 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 32.7”, the lowest seat adjustment 32.1” and the highest seat adjustment 33.3”. 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 fiber 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 aluminum. This construction results in added stability when compared to traditional construction techniques.
A dry weight of 322 lbs (DIN empty 377 lbs) is hard work. Each component was weight-optimized or discarded if it is not absolutely necessary. The weight reduction continues down to the finest details, even to the point of saving a single gram from parts while maintaining or improving their function. For instance, titanium screws are used in the engine and frame in a limited number of metric sizes, to not only save weight but to also reduce the number of tools needed.
