The BMW HP2 Sport represents the pinnacle of Bavarian flat-twin history. A sports car for gentlemen, aesthetic pilots and amateurs of the nobility of sport. Before the S 1000 RR spread its thunderbolt on the circuits, the HP2 had marked the ground in 2008, heralding a formidable return of the Munich brand in the competition.. What a treat to see this machine roaring over the 24 hours of Le Mans and the Bol d´or.
It is now possible to afford this little gem adorned with the colors of BM’s sports department. Its blue-red-white livery…. Pardon, Alpine White, Lupine Blue metallic and Magma Red is the same as that worn by the endurance bike in 2008. Blue frame and front rim, white rear wheel, racing deco, sponsor stickers on the belly and, a little twinkle. eye, number 17 on a green background, exactly as in world endurance (the green number plate is the one allowing the motorcycle to be entered in the prototype category). Superb, this HP2 Sport Motorsport Replica is on sale now, with a circulation limited to 400 copies. What to have fun if the wallet tells you. Except that you are not in the presence of a sportswoman like the others. A little reminder about this BMW which defied the track: between the endurance prototype and the production version, there are really … few differences:
The flat twin now reaches the speed of 9,500 rpm and spits out 130 horsepower. To achieve these higher revs, the twin cylinder heads have been thoroughly revised and subjected to even more extensive testing. Two chain-driven overhead camshafts and ultra-light pawl actuated valves now allow the engine to run at a maximum speed of 700 rpm above that of the R 1200 S. The four radially arranged valves ensure very compact combustion chambers, so that it was possible to dispense with the second spark plug used so far on the R models. The compression ratio is 12.5 to 1. BM recommends SP 98 as a fuel but the engine accepts 95. The horizontal arrangement of the camshafts implies two peculiarities: each shaft controls an intake valve and an exhaust valve and the cams are conical in shape. To increase the gas flow, the diameter of the valve head has been increased from 36 millimeters on the intake side and from 31 millimeters on the exhaust side. The intake ducts have been optimized by machining. As on the K 1200 engines, the pawl control technique uses shims placed on the valves.
An essential tool for competition, the shifter is making its first appearance in series on a machine. BM is ahead of the Japanese and the Italians on their own ground (adaptation of racing solutions for the series). This system makes it possible to change gears very quickly without cutting the throttle or disengaging the clutch. If the pilot activates the selector, the electronic engine management acts on the ignition angle and couples the injection. The kinematic chain therefore switches to “reduced load” for the gear change which can then be carried out very quickly without actuating the clutch. The shifter works both according to the normal gearshift grid and, on request, to the reverse grid for the stroke (pressure sensor in the range of accessories). On the other hand, if the pilot actuates the clutch, the system does not come into action. Whatever the situation, the bike leaves the rider to decide whether to use the shifter or not.
The braking system of the new BMW HP2 Sport uses one-piece Brembo calipers (as on the Ducati 1098) with four radially mounted pistons, biting 320mm diameter discs. Radial screwing is carried out by means of a new cast iron lug located on the lower part of the Telelever. The rear wheel is calmed by a double-piston floating caliper. Sport requires, the brake hoses are aviation type. As an option, BMW offers an ABS suitable for sports use. The system has been optimized in terms of its rear wheel anti-take-off function. An additional pressure sensor integrated into the front brake circuit allows finer regulation of the system and prevents the electronic unit from opening the front brake too early when the rear wheel is heavily unloaded. However, the driver has the option of disconnecting the ABS when going on the circuit..
The instrument cluster fitted as standard to the cockpit of the BMW HP2 Sport is a technological gem, developed in cooperation with the company 2D Systems (whose systems are also implemented for the acquisition and analysis of data in GP). The handset has a large digital display and different operating modes. It is controlled using two switches on the left stalk.
– In Road mode, the pilot is shown typical information, such as RPM, speed, time, mileage, remaining range and elapsed time, and receives information on the warm-up phase of the engine..
– In Racing mode, the display shows indications, for example, on lap times, maximum speed, top speed or the number of gear changes. The stored data can also be read on a laptop computer. In its upper part, the instrument cluster also incorporates eight diodes which can be used to indicate the speed or as shift-lights. In addition to other functions, the displayed information can be freely programmed. Finally, the GP instrument cluster offers numerous possibilities for expansion. Thus, it is possible to connect laptimers (timing the times per lap) with transmitter / receiver unit, GPS tracking or data logger on an additional input.
The upper triple clamp as well as the two flanged handlebars, adjustable on the vertical axis, are refined forged parts in solid-milled aluminum. At this level, we also find the brake master cylinder as well as the radial piston clutch master cylinder, which are fixed using quick-release clamps, like what we find in the race.
A set of beautiful pieces, installed to the delight of amateurs and racing professionals. With all of its technical modifications, the dry weight of this BM is only 178 kg, and 199 in running order without the fuel, making it a German almost as light as a Japanese. This weight loss as well as various racing adaptations allow you to have a competency in your hands..
Less kilos = more liveliness. So, we put in what it takes: a carbon fiber fairing, a one-piece and self-supporting rear shell, a steel trellis frame revised accordingly and new die-cast wheels even lighter..
When it comes to efficiency, the HP2 Sport comes out on top. The Telelever and Paralever suspension systems are completed by a set Öhlins adjustable in all directions. The rear shock absorber also makes it possible to adjust the attitude of the motorcycle. A revised gearbox staging, tighter, allows to keep all the gniak of the engine in the intermediate reports. And to ensure performance for several hours, the ergonomics have not been left behind. Eccentrically adjustable footrests secure your boots onions, and a lot of things are adjustable on the HP2: selector and brake lever, milled die-cast aluminum handlebars adjustable on several
Magura axles and levers with radial master cylinder (for brake and clutch) adjustable in depth.
To output 130 horsepower while ensuring reliability worthy of an endurance machine (which it represents), in addition to the modifications mentioned above, new forged and lightened pistons of high resistance as well as adapted connecting rods take place in the cylinders.
The shape of the nostrils typical of Bavarian productions has been enlarged and optimized in the wind tunnel to better cool the 2 oil radiators located behind. The air channeling and optimal heat removal have been particularly studied.
The hunt for weight has been done everywhere. But true to its philosophy of respect for the environment, the brand has taken care to install a three-way catalytic converter, even if it costs a few kilos. Everything around it is designed for racing: an exhaust valve is there to strengthen the torque curve. On leaving the cylinder heads, the exhaust line now passes under the engine to improve the angle grip. The pot, very design, is supposed to deliver an impressive sonorous roar typical of the Boxer. To see … but if there is an option of the same pot as the one used in Endurance, it will be a choice to make absolutely: at the Bol d’Or, the proto gave off the same boom as that of an airplane engine of the second world war. To bristle your hair 😉
Could the HP2 Sport be BMW’s answer to competition? Not yet. This motorcycle was not designed to compete with a GSX-R or an R1 for track or race performance. It is about offering enthusiasts the ultimate evolution of Boxer sportiness for the track. Something exclusive, with a very pronounced racing taste … the culmination of a challenge that BMW had launched. But at MP, we recently thought that an HP4 version, with all these technical solutions and a powerful and light 4-cylinder (BM, engine manufacturer in F1, can do it) would be a formidable weapon against the Japanese armada. We just messed up the name – BMW’s new ultimate sport identity is called S 1000 RR. Also available in Motorsport colors.
