BMW HP4 RACE

OTR

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.

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

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.
