Purebred racer in BMW HP4

SURPASSES SUSPENSION OF SUPERBIKES WITH ITS CARBON FIBRE FRAME Meeting highest demands of racing technology in spring elements and brakes.

-

Fascinatin­g technical solutions for maximum performanc­e on the race track have always been the hallmark of handpicked 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 specialise­d 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 fibre frame. Weighing 171kg when fully fuelled 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 fibre and weighing just 7.8kg 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% as compared to light alloy forged wheels while retaining a deliberate­ly rigid design.

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 swing arm 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 the HP4 RACE also has parts otherwise only to be found in World Cup machines. Coated titanium pistons and single-piece aluminium calipers with chemically nickel-plated surface make for what is currently the very best combinatio­n of materials available.

The purebred racing engine has a peak output of 158kW (215hp) at 13900rpm. The maximum torque of 120Nm is reached at 10 000rpm. The maximum engine speed has been increased compared to the engine of the S1000 RR from 14 200rpm to 14 500rpm. With the aim of achieving the best possible performanc­e, a six-speed close-ratio racing gearbox is used with optimised transmissi­on ratios and various secondary ratios.

The BMW HP4 RACE comes

The new BMW HP4 RACE will be available in South Africa, September 2017. with an extensive package of electronic control and assistance systems as well as a weight-optimised on-board electrical system which has been optimised to meet racing needs. A wealth of informatio­n is available on the 2D dashboard with transferab­le data memory 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 bike. Other electronic features are the Pit Lane Limiter for observing speed limits in the pit lane and Launch Control for perfect race starts.
