It's produced in small batches and BMW says it's going to make the chassis available on the aftermarket to let bike builders do their stuff - and to let HP4 Race owners fix their bikes if they damage the frame.
At the ongoing Auto Shanghai 2017, BMW Motorrad has showcased the production version of the 2017 BMW HP4 Race.
Weighing just 171 kilograms, the HP4 Race is lighter than the factory racing bikes now used in the Superbike World Championship and is slightly above the MotoGP factory racers in terms of weight.
The HP4 Race has been built purely for the race track, and will come with a 215 hp World Superbike spec engine.
The engine, which produces 215 horsepower at 13,900 rpm and 88.5 ft/lbs of torque at 10,000 rpm, is based on the FIM Endurance World Championship and WorldSBK S 1000 RRs.
In order to achieve these numbers, BMW's engineers made modifications to the standard 999 cc, in-line four from the S 1000 RR that include connecting rods made of high-strength forged steel and a lighter crankshaft. The mill is mated to a six-speed close-ratio racing gearbox.
Rounding out the electronics suite is a pit lane speed limiter, launch control, wheelie control, spring travel and brake pressure sensors. Also available is a 2D data logger.
Akin to what's in use in the Superbike World Championship and in MotoGP, HP4 Race is fitted with the Ohlins FGR 300 inverted fork and TTX 36 GP monoshock suspension. The total dry weight of the bike is pegged at 145 kg.
Carbon-fibre wheels are nothing new: Blackstone Tek of North Riding in Johannesburg has been making them for more than a decade as aftermarket fitment for road and track (with more than 22 000 sold, the technology is well proven) but this is the first time carbon-fibre wheels have been specified as factory kit on a BMW motorcycle. Coated titanium pistons, Brembo GP4 PR monoblock aluminium brake calipers, and braking system are also borrowed from race bikes.
The carbon fibre trim, intake silencer cover and the seat hump in the new HP4 Race feature the BMW HP Motorsport colours.
The BMW HP4 RACE is highlighted by three chassis elements constructed entirely of carbon fiber: monocoque main frame, self-supporting rear subframe, and wheels. Even the electrical system has been optimised for weight, with a tiny 5Ah lithium ion battery.
The bike comes with a bewildering array of electronic control and assistance systems, including dynamic traction control, engine braking regulation and wheelie control, each of which can be programmed through 15 levels, individually for each gear.
Engine Brake EBR (programmable for selected gears at 15 levels).
United Kingdom price of £68,000 and available from September 2017.
