BMW HP2 Sport Tech
The HP2's 2D dashboard features a number of programmable features and modes. In street mode, speed is shown on the top right, while gear position is smaller and inset into the block in the lower right. In race mode, the two are reversed. The shift lights across the top are fully programmable, a lap timer can be operated by the switchgear or a trackside beacon, and the system is expandable to include GPS tracking and datalogging.
The valve pockets in the forged flat-top piston clearly show the radial arrangement of the valves. The new valves are 39mm (intake) and 33mm (exhaust), up from 36mm and 31mm, respectively. New rods are correspondingly updated to cope with the engine's increased power.
A chain drives the double overhead cams, with drag levers actuating the valves themselves. The camshaft lobes are ground spherically to attain the radial layout, much like the cams in MV Agusta's F4 models. The new layout means there is no need for two spark plugs in each cylinder as used on the R 1200 S.
The rear Ohlins shock has adjustments for spring preload, compression and rebound damping, and ride height. The front shock is adjustable for spring preload and compression and rebound damping, and ride height is changed by sliding the lower outer tubes in the bottom triple clamp. On the Telelever setup the inner top tubes serve only to locate the front end, and the individual fork tubes are not functional in the conventional sense.
Multi-adjustable rearsets are beautifully machined, and the shift shaft incorporates a switch for the quickshifter. Using an optional switch the shifter can be easily reversed for race pattern. Inside the engine, first and second gear are taller, closing up the overall ratios.
The HP2's frame-what little there is of it-is identical to the R 1200 S with the exception of mounts for the self-supporting tailsection. The stainless steel exhaust's catalytic converter is underneath the engine, helping to lower the center of gravity compared with the R bike, and a servo-controlled exhaust valve is used. An 02 sensor in each headpipe monitors air/fuel ratios.
Rider's-eye view of the HP2 Sport shows numerous high-end parts and attention to detail, including machined-from-solid top triple clamp, 2D MotoGP-derived dash, carbon-fiber fairing and Magura radial-pump master cylinders. | 
The intake ports are CNC-machined for consistency across the production run. | 
This single-plate clutch is typical of BMW Boxers and easily handled the HP2's increased horsepower. Note the small balance shaft underneath, used to quell the bike's rocking-couple vibration. |
The clip-ons are adjustable using this small eccentric in one of the mounting slots. In one position, droop is six degrees; in the other, nine. | 
Brembo radial-mount calipers attach to the specially machined lower Telelever tubes; wheels are forged aluminum, the rear a half-inch wider than the R 1200 S hoop. | 
BMW's Paralever shaft-drive arrangement does an excellent job of reducing shaft jacking and also allows the wheel to be quickly removed. |
