Last November BMW gave a glimpse of their upcoming HP4 Race, and now, during a press conference at the 2017 Shanghai Auto Show, they have provided details on this exclusive machine. Limited to a run of just 750 handmade machines, the HP4 Race will feature plenty of carbon fiber including a monocoque frame weighing just 17.2 lbs (7.8 kg), a self-supporting rear frame with three-stage height adjustment, rims that are 30 percent lighter than the previous light alloy forged wheels, and various trim pieces mounted using snap fasteners. BMW says this is the first motorcycle in the world to offer a fully carbon frame and fully carbon wheels bringing the weight down to just 321 lbs (dry).
The HP4 Race’s inline four-cylinder engine follows Endurance and Superbike World Championship rules and provides a max 215 hp (158 kW ) at 13,900 rpm, which is up 16 hp from the standard S1000RR specs. BMW says each engine is built by specialists, run in and checked on the dyno to ensure every engine matches the required power curve. It then gets its first service, including an oil change, is endoscoped, and the control times and valve clearance are adjusted… meaning the HP4 Race is ready to race as soon as it’s delivered. A six‑speed close-ratio racing gearbox is used with optimized transmission ratios and various secondary ratios and includes pinion and chain sprocket options.
Ready to race straight from the factory, the HP4 Race has an FGR 300 upside-down fork and TTX 36 GP shock from Öhlins—these are identical parts to those used in both the Superbike World Championship and in MotoGP. The light alloy underslung swingarm made of milled and sheet metal parts is also a component used in the Superbike World Cup. The two Brembo GP4 PR monoblock brake calipers used can also be found in World Cup machines. Coated titanium pistons and single-piece aluminum calipers with chemically nickel-plated surface make for what is currently the very best combination of materials available. In conjunction with 6.75 mm thick 320 mm diameter T-type steel rotors, the system should provide outstanding brake performance.
An extensive package of electronic control and assistance systems as well as a weight-optimized onboard electrical system will meet the racer’s needs. A wealth of information is available on the 2D dashboard with transferable data memory (2D logger). Wide-ranging set-up options for different track layouts and road surface conditions are provided by the audible Dynamic Traction Control, Engine Brake EBR and Wheelie Control. These can be programmed selectively for each gear according to rider preference. Other electronic features are the Pit Lane Limiter for observing pit speed limits and Launch Control for perfect race starts.
While BMW may no longer be fielding a factory race team, they are showing their willingness to support privateers by creating a new race-ready bike with the latest hardware and technology. We’ll have to wait and see how well the HP4 Race competes on the track against other brands, which are bringing out higher performance machines. You can read BMW’s press release below, and see all the photos in our HP4 Race photo gallery.
The new BMW HP4 RACE.
The new BMW HP4 RACE: individually crafted high-tech and innovation for top performance on the race track.
Fascinating technical solutions for maximum performance on the race track have always been the hallmark of hand-picked factory racing motorcycles modified to perfection down to the last detail. With the new HP4 RACE, BMW Motorrad presents a purebred racing bike in a production run of 750. It is individually crafted by a small, highly specialized team, ensuring the very highest level of quality.
In terms of engine, electronics and spring elements, the new HP4 RACE is in the same category as current superbike factory racing machines, even surpassing this level in the area of suspension with its carbon fiber frame. Weighing 377 lbs. (171 kg) when fully fueled and road ready, the new HP4 RACE is even lighter than the factory racing bikes currently used in the Superbike World Championship and is only slightly above the MotoGP factory racers in terms of weight.
With the HP4 RACE, BMW Motorrad is the first motorcycle manufacturer in the world to present a main frame made entirely of carbon fiber and weighing just 17.2 lbs. (7.8 kg) that is produced industrially in small series, thereby making this future-oriented technology available for anyone to purchase. The front and rear wheel are also made of this high-tech material, enabling a weight reduction of approximately 30 percent as compared to light alloy forged wheels while retaining a deliberately rigid design.
Öhlins spring elements, light alloy underslung swingarm and Brembo monoblock brake calipers from the Superbike World Championship.
The new HP4 RACE likewise meets the highest demands of racing technology in the area of spring elements and brakes. Both the FGR 300 upside-down fork and the TTX 36 GP spring strut are supplied by the Swedish manufacturer Öhlins, with identical parts being used both in the Superbike World Championship and in MotoGP. The light alloy underslung swingarm made of milled and sheet metal parts is also a component used in the Superbike World Cup.
Featuring two Brembo GP4 PR monoblock brake calipers, the brake system of new HP4 RACE also has parts otherwise only to be found in World Cup machines. Coated titanium pistons and single-piece aluminum calipers with chemically nickel-plated surface make for what is currently the very best combination of materials available. In conjunction with 6.75 mm thick 320 mm T-type racing steel brakes, the system ensures stunning brake performance.
The new HP4 RACE has a purebred racing engine similar to specifications 6.2 and 7.2 as in the Endurance and Superbike World Championships. The peak output is 215 hp (158 kW ) at 13,900 rpm. The maximum torque of 88.5 ft-lbs. (120 Nm) is reached at 10,000 rpm. The maximum engine speed has been increased as compared to the engine of the S1000RR from 14,200 rpm to 14,500 rpm. With the aim of achieving the best possible performance, a 6‑speed close-ratio racing gearbox is used with optimized transmission ratios and various secondary ratios (diverse pinions and chain sprockets included).
Weight-optimized electrical system, 2D dashboard along with Dynamic Traction Control DTC, Engine Brake EBR, Wheelie Control and other electronic features.
The new BMW HP4 RACE comes with an extensive package of electronic control and assistance systems as well as a weight-optimized on-board electrical system which has been optimized to meet racing needs. A wealth of information is available on the 2D dashboard with transferable data memory (2D logger).
Wide-ranging set-up options for different track layouts and road surface conditions are provided by the audibly perceptible Dynamic Traction Control controlled by ignition cut, Engine Brake EBR and Wheelie Control. These can be programmed selectively for each gear according to rider preference, allowing optimum use of the enormous riding dynamics potential offered by the new HP4 RACE. Other electronic features are the Pit Lane Limiter for observing speed limits in the pit lane and Launch Control for perfect race starts.
