2012 BMW HP2 Sport 2012 Moto Racing Boxer

The dream of many Boxer fans has come true: With the new 2012 BMW HP2 Sport, BMW Motorrad is putting the sportiest, most powerful and lightest Boxer series of all times on the road. The third model of the HP model range was designed for the ambitious sports rider and enthrals with numerous exclusive details that were previously restricted to racing, some making their first appearance in series vehicle production.

Examples of these include the self-supporting and aerodynamically optimised fairings made completely of
CFK, the gear shift assistant, a dashboard like that used in the MotoGP, the forged aluminium wheels and the racing brakes with radially bolted calipers. Wherever the eye of the spectator wanders, it sees pure racing technology that delights every enthusiast. It is unmistakably athletic, a vehicle that inspires on country roads as well as on the racing circuit.

Regardless of the limits for the engine output as a result of the principle and the aerodynamic disadvantages from the cylinder configuration of a Boxer, BMW Motorrad deliberately decided to further develop this historic engine concept for a road racer with racing circuit talent. The key engine data are very respectable: the engine achieves more than 96 kW/128 bhp at 8750 min compared with the significantly modified engine of the BMW R 1200 S. The maximum torque lies at 115 Nm at 6000 min, the highest revs of the engine reaches a peak value at 9500 min.

Technically, the BMW HP2 Sport is based on the BMW R 1200 S. Customised to meet the requirements of the ambitious sports rider down to the last detail, the BMW HP2 Sport is however a completely independent and absolutely exceptional motorcycle. Many detailed solutions are based on the experiences gained in longdistance races.

The most striking difference of the BMW HP2 Sport from the endurance racing Boxer is the brand new cylinder heads: Each of the double overhead camshafts (DOHC) uses a drag lever to actuate the valves that are larger than in the BMW R 1200 S. Further modifications such as the flowoptimised intake and outlet, new forged pistons and adapted connecting rod help the engine to achieve the necessary higher output compared to the basic engine.

The new stainless steel exhaust system is placed below the engine for the first time. This keeps the
construction of the lower area of the motorcycle extremely slim, enabling great freedom of movement for
the familiar ‘hanging off’ riding position, and the fitting of a CFK engine spoiler is advantageous to the aero-dynamics. An inimitable boxer sound with new acoustic quality is generated by the exhaust system and the striking design of the rear silencer is impressive.

Another exclusive racing feature is the gearshift assistant together with the narrow ratios of the 5-speed
gearbox to enable fast gear changes without having to ease off the gas and operate the clutch. This technology
is offered for the first time in a series vehicle. In order to adapt the gearshift pattern for the racing circuit, a suitable replacement pressure sensor is available as special equipment if necessary.

The fully adjustable hlins sports chassis also has a Brembo monoblock brake system with radially mounted,
four-piston fixed calipers at the front. Optimum ergonomics are ensured by the adjustable forged aluminium footrests, the adjustable stock handlebar and the Magura radial manual buttons. The series dashboard that comes directly from MotoGP sport provides the rider with important information and can also deliver lap times plus other racing relevant data as well as the usual displays.

Attention was paid consistently to the lightweight construction of all com-ponents. This includes not only
the self-supporting front fairing and the likewise selfsupporting carbon rear or the weight-optimised forged
wheels, but also hidden details such as the lightweight generator from the racing world. That’s how it was
possible to reduce the unladen weight of the HP2 Sport to DIN standard with full tank (90%) to 199 kilos. The dry weight is a mere 178 kilos.

The interplay of variable ergonomic design, increased engine output and the favourable centre of gravity of the Boxer guarantees superb handling and racing potential. Even if racing fascination is clearly at the forefront of
the BMW HP2 Sport, it does not have to forego the safety design feature of ABS. The sophisticated anti-blocking system specially adapted to the HP2 Sport is available as an option and is configured so it can be switched off for the racetrack.

“2012 BMW HP” is the abbreviation for “High Performance” and the “2” in the model designation of this supremely sporty BMW describes the two-cylinder Boxer engine. The term “High Performance” stands symbolically for the sporting performance idea, the achievement potential of the entire vehicle. “High Performance” that is the skilful harmonization of all the individual components into a convincing whole that is more than the sum of the individual parts. It is the synonym for a well thoughtout overall design and perfection right down to the last detail, for the very best driving characteristics and pure, unadulterated riding pleasure. It goes without saying that “HP” also stands for the prestige connected with an exceptionally high-quality and exclusive vehicle.

After the HP2 Enduro and the HP2 Megamoto, the HP2 Sport is the third representative of an independent motorcycle category from BMW fitted with the historic Boxer engine. All the HP2 motorcycles mentioned use the technical basis of production vehicles, but are clearly differentiated by an uncompromising interpretation of their actual purpose through a conspicuous and emphatically resolute sports orientation and exclusive product features.

The new BMW HP2 Sport extends the HP model range of BMW Motorrad. It is a descendant of the BMW R 1200 S. Apart from established concepts such as the BMW Motorrad Telelever and EVO Paralever as well as the cardan shaft drive, almost all components were newly developed or at least modified to a large extent. Weight saving, increased performance plus the uncompromising sporty configuration was top of the agenda in the list of requirements for the development engineers.

A complete redesign of the cylinder heads allowed the Boxer to reach higher revs. Extensively tests in
endurance events followed in addition to the usual tests. Double overhead chain driven camshafts (DOHC) and valves actuated by very light drag lever now enable top revs of 9500 min. The four radially arranged valves ensure extremely compact combustion chambers so that there is no need for the second spark plugs as used in the R models until now. The compression ratio is 12.5:1. Super Plus with 98 RON is recommended as the fuel for optimum performance although the motorcycle can also run on Super 98 RON.

The horizontal arrangement of the camshafts introduces two special features: Each of the shafts controls an
intake and outlet valve and the cams are conically ground. For a higher gas throughput, the valve plate diameter was increased from 36 to 39 millimetres (intake) and from 31 to 33 millimetres (outlet) respectively. The intake channels were machined for optimisation. The operating technology with drag lever works with shims sitting on the valves as in the K 1200 engines. The cylinder head covers are made from carbon and fitted with easy-to-replace slip pads made from PA6 hard plastic.

The bore and stroke ratio is unchanged in the HP2 Boxer. The high-strength, weight-reduced forged piston and the correspondingly adapted conrod are new. Interacting with the new intake pipe system with its a short intake air funnel, the power plant develops a top performance of 96 kW/128 bhp at 8750 min and a maximum torque of over 115 Nm at 6000 min.

In contrast to the gearbox of the BMW R 1200 S, the first and second gear have higher ratios so that the gear increments are closer. This results in a lower drop in revs when changing up in gear. This configuration is also a typical racing feature that benefits the dynamic driving characteristics.
