At the tail end of last year, BMW teased the attendees at the EICMA motorcycle show by exhibiting a replica of its HP4 Race superbike-fully designed with wheels and an all-carbon frame. At that time there was scanty information on the ground relating to the bike’s power figures, engine changes or final weight. The only thing that the president of BMW Motorrad, Stephan Schaller, was willing to reveal was that the HP4 Race bike would have an all-carbon fiber main frame and carbon fiber rims. But the company has now come out with details about the bike's mind-blowing specs, together with plans to make a limited number of 750 hand-made machines.
The generous use of carbon fiber takes the wet weight of the HP4 Race superbike to a lean 377 pounds (171 kilograms) while carrying fuel and 141 kilograms when dry. That makes it lighter than the majority of superbikes and only slightly heavier than the MotoGP factory racers. The frame weighs in at just 17 pounds (7.8 kilograms) on its own.
The BMW HP4 Race superbike further combines aspects of both MotoGP and Superbike by being fitted with a complete Ohlins suspension (with a TTX 36 spring strut and the FGR 300 upside-down fork), Brembo GP4 PR monoblock brake calipers and a swing arm made of light alloy.
When it comes to engine performance, the HP4 Race boasts of a jaw-dropping peak output of 215 horsepower (or 158 kW) at 13,900 rpm while the maximum torque is recorded at 88.5 pounds per foot(or 120 Newton-meters) at 10,000 rpm. In comparison, the 2017 version of the BMW 1000 RR reaches 199 horsepower(148 kW) and generates 83 pounds per foot (or 113 Newton-meters) of torque.
So as to attain these figures, the engineers at BMW modified the standard 999 cc, in-line four-stroke, a four-cylinder engine used in the BMW S 1000 RR Superbike that incorporates a connecting rod that was designed using a lighter crankshaft and high-strength forged steel.
To cope with the proclaimed speed of over 186 miles per hour (300 kilometers per hour), the HP4 Race is also equipped with a wide range of built-in electronic controls and assistance systems, including Engine Brake EBR, Wheelie Control, and Dynamic Traction Control. Riders can program these controls for each gear based on their individual preferences.
Extra electronic components incorporated into the BMW HP4 Race Superbike include a Pit Lane Limiter to maintain the bike at speeds suited for pit lanes and Launch Control to ensure smoother starts for races.
More trackside adjustments may be made using a rear frame that can be assigned three different heights and an eight-position footpeg arrangement.
Today’s race-ready motorbike also requires having a way of monitoring the rider and analyzing bike performance. This is provided by an integrated 2-D dashboard that tracks rider information including EBR settings, lap time, engine mapping and DTC settings. Other details include mechanical information such as throttle position, water temperature, lean angle, brake pressure, front and rear wheel speed and spring travel.
As one would expect, all these limited edition technological features do not come cheap. The BMW HP4 Race Superbike will be available starting from the month of September, and you can buy one for only US 87,000(£68,000).
