Edge On Motorcycling- The BMW HP2 Sport
by: Kevin Crockett
The BWM HP2 Sport is the latest iteration of the Bavarian Motor Company's foray into producing performance driven motorcycles. The quiet, staid, and lets just admit it boring motorcycles that came out of BMW in years past is history.
The HP line is BMW's new high performance, cutting edge line up. It's the motorcycle equivalent of their M line of performance cars.
The HP2 Sport is the third motorcycle in the HP line following the releases of the HP2 Enduro and the HP2 Megamoto.
The HP-2 Sport is based on the R1200S but is out and out designed for sports riders who are looking for a machine that has performance as well as endurance.
The HP2 Sport keeps some of the concepts that BMW motorcycles have become known for such as the BMW Motorrad Telelever front suspension and the EVO Paralever rear suspension. Other components have been newly developed or highly modified for use in the motorcycle.
The HP-2 Sport is powered by a twin Boxer motor that has a capacity of 1170 cc. The engine's cylinder heads were completely redesigned which allows the engine to rev as high as 9500 rpm. The engine has a 101 mm bore and a 73 mm stroke and produces a maximum of 130 hp at 8,750 rpm and 85 lb-ft of torque at 6,000 rpm.
The bike has a close ratio six speed gear box, with first and second gear having higher ratios. This puts the gear increments closer to each other and results in less of a rev drop when progressing up through the gears.
The bike also has a gear shift assistant which allows the rider to shift gears without using the clutch. It works by sensing when the gear lever is activated. If it senses gear lever activation without the use of the clutch, it electronically reduces power to the engine which puts the engine in a low load state and makes it possible to shift without the clutch. If the rider uses the clutch, the system becomes inactive.
The riding position of the HP-2 sport can be described as relaxed. BMW has extensive experience with endurance racing and knows that for racers to be fast over a long period staying power is more important than a full racer's tuck.
The dashboard was developed by 2D Systems, which also provides analytic recording systems to Moto GP racing.
The dashboard has two modes and is switched by two controls on the left handlebar. In road mode, typical information such as speed, rpm, time, and distance are displayed. In race mode data such as top speed, circuit times, number of gearshifts and rpm is shown.
The HP2 Sport will push BMW further into the world of performance motorcycling.
