At EICMA last year BMW teased sportbike fans with an exclusive, carbon fiber-rich HP4 RACE edition motorcycle and now the Bavarian brand has released extensive details on the machine. As indicated back in November, some of the highlights include a full monocoque carbon fiber main frame weighing a claimed 17.1 pounds, carbon fiber wheels and rear frame.
But BMW didn’t stop there, completely decking-out the machine for race duty with all sorts of high-end touches. The limited production run includes just 750 “individually crafted” units. There’s no word in the release on how to acquire one of these masterpieces, nor what BMW is going to charge for one of its HP4 RACE motorcycles in the USA. Reports from elsewhere in the world price the HP4 RACE at around 80,000 EUR, which would be in the ballpark of $85,000 – $86,000. These are currently unconfirmed numbers, however.
As for the frame, BMW adapted techniques used in the production of its automobiles to create the elements of the HP4 RACE. According to BMW, it’s the “first company in the world to industrialize the carbon fiber manufacturing process for large-scale volume production in car making.”
Specifically, BMW uses a process called Resin Transfer Molding for the main frame. This is where the fabrics used in the creation of a piece are placed in a mold and then “injected with reactive dual-component resin.” BMW has refined the process to strike a balance between optimal stiffness and flexibility, so as to offer riders superior feel when pushing the pace on track.
The rear frame didn’t necessitate the use of Resin Transfer Molding, and is constructed in the more common hand-laid technique. It can be adjusted to three different levels for choice among seat heights between 32.1 inches at the lowest and 33.3 inches at the highest. Ergonomic options increase thanks to the eight-position adjustable milled aluminum foot pegs also.
Essentially, the same engine found in the S1000RR powers the HP4 RACE, but it does have some additional oomph. Head of 4 and 6-Cylinder Product Projects Rudolf Schneider is quoted saying “the engine of the new HP4 RACE is a factory racing engine at World Cup level.”
That means 215 horsepower at 13,900 rpm, 16 more ponies than the S1000RR, and 83.3 lb-ft of torque at 10,000 rpm. The rev limit rises to 14,500 rpm from 14,200. Revised intake and exhaust camshafts contribute to the increased power. The pistons and Pankl-made connecting rods are specifically selected to optimize weight. Race-spec bearing clearances and an updated oil sump ensure all the moving parts function with the utmost precision. A 4-in-2-in-1 titanium exhaust is wrapped in carbon fiber also.
BMW revised the six-speed gearbox, tweaking the ratios for all but third gear to provide improved performance on track. That means taller first and second gears and shorter fourth, fifth and sixth gears when compared to the standard S1000RR. The HP4 RACE has a reversed shift pattern, similar to the one used in WorldSBK, and HP Shift Assist Pro, allowing clutchless upshifts and downshifts, is included too.
A top-of-the-line Ohlins FGR 300 USD fork and TTX 36 GP rear shock suspend the package. In addition to the full suite of adjustability options for the Ohlins kit, BMW also includes inserts that allow easy adjustment of the offset and steering head angle, as well as the geometry of the swingarm. Brembo GP4 PR calipers, typically reserved for international competition, bring the HP4 RACE to a stop.
Race-focused electronics abound and have been streamlined to be as lightweight as possible. There’s Dynamic Traction Control, a Pit Lane Limiter, Engine Brake management, Wheelie Control, Launch Control and a variety of riding modes. A 2D dash displays rider and mechanic information, the mechanic display only available when the bike is at an idle. The rider sees things like lap time, best lap, DTC setting, Map settings, water temperature and the like. The mechanic display has elements such as rear wheel speed, throttle valve position, spring travel front and rear, brake pressure front and rear, banking position and water temperature.
The lithe machine is 377.8 pounds, ready to ride and it comes on Pirelli Diabolo Superbike Slicks, 120/70 17 in the front and 200/60 17 in the rear.
In other words, the new BMW HP4 RACE is a doozy of a track bike. Check out the full specs below.
