MADRID – German auto manufacturer BMW’s motorcycle division, BMW Motorrad, announced on Thursday it will only build 750 units of its new circuit bike with the same specifications as those racing with the company’s official Superbike World Championship team.
The BMW HP4 Race also boasts some pioneering firsts in factory racing motorcycles. For instance, it is the first bike in the world to offer an optional main frame made entirely of carbon fiber, weighing just 7.8 kilograms (17.2 pounds).
The front and rear wheel are also made of carbon fiber, enabling a weight reduction of around 30 percent compared to light-alloy forged wheels.
The bike weighs – fuelled and fully loaded – a spectacular 171 kg (377 lb), slightly lighter than a Superbike and slightly heavier than a MotoGP racing bike.
The HP4 Race also meets the highest standards on its spring elements and brakes.
Both the FGR 300 upside-down fork and the TTX 36 GP spring strut, made by Sweden’s Öhlins, are also used in the Superbike World Championship and in MotoGP.
The braking system boasts two Brembo GP4 PR monoblock brake calipers, with components only found in World Cup machines, such as coated titanium pistons and single-piece aluminum calipers with a chemically nickel-plated surface.
The above set-up operates in conjunction with 320-milimeter, T-type racing steel brakes that are 6,75 millimeters thick, providing a stunning brake performance.
The engine gives 158 kilowatts (215 horsepower) at 13,900 revolutions per minute. The maximum torque of 120 newton meters is reached at 10,000 rpm.
Compared to the S 1000 RR powerplant, the HP4 Race’s maximum rpm is of 14,500, versus 14,200 rpm for the former.
Seeking the best possible performance, the BMW HP4 RACE has a 6-speed close-ratio racing gearbox with optimized transmission ratios and various secondary ratios (diverse pinions and chain sprockets included).
The bike has very flexible set-up options for track layouts and road conditions, including Dynamic Traction Control controlled by ignition cut.
It also offers Engine Brake EBR and Wheelie Control, which can be programmed selectively for each gear according to rider preference.
Other electronic features are the Pit Lane Limiter for observing speed limits in the pit lane and Launch Control for perfect race starts.
With a reported top speed in excess of 300 km/h (186 mph), an estimated 81,000 euro ($87,000) is the price requested to sit on and enjoy this two-wheeled rocket.
