HP2 Sport
The new model from BMW's HP High Performance division has been developed by a
dedicated team of veteran racers, engineers, and mechanics. Experience from
Boxer racing, including a number of races in the endurance world championship of
2007, has been a key component in development of this machine. The BMW endurance
team's accomplishments in its first year included a class win at the Le Mans
24-hour race.A
completely new cylinder head design has allowed the Boxer to rev higher and
produce more power. Dual overhead cams are used for each cylinder, operating
four radially arranged valves. The legendary Boxer maintainability lives on in
this tough engine: a welcome contrast to other exotic Twins. The new close-ratio
six-speed gearbox features an electronic "shift assistant" for full-throttle
clutchless upshifts - the first time this technology has been offered in any
street motorcycle.
Light weight is
important in a sport bike but essential in a race bike. BMW engineering combines
with premium components to offer a dry weight of only 392 lbs (178 kg) in this
1200cc street-practical Boxer Twin. Suspension struts are by Ohlins, Brake
calipers are Brembo monoblocs; the list goes on. All fairing parts are carbon
fibre including the seat support structure.
Details of high
performance and BMW technology abound, from the many milled aluminum parts to
the data-logging digital/analog dashboard. The under-seat exhaust features an
electronically-controlled flap, giving compliance with noise regulations while
increasing exhaust flow under hard use. BMW's light 2-channel ABS antilock
braking system is available and can be switched off for racing and track riding.
The unique ergonomic
requirements of a motorcycle used in long-distance racing have led to an
adjustable riding position that lets the rider move around and is more relaxed
and upright than even the comfortable R1200S model the HP is based upon.
The HP2 Sport will be
made in very limited quantities. In Canada, bikes are to be shipped only to
dealers who are holding deposits for sold units. HP2 Sports will be seen in the
national Canadian Thunder Championship, replacing the R1200S bikes that won the
series for BMW Canada last year.
