BMW has unveiled the third model in its High Performance range,
the HP2 Sport.
It is the fastest, sportiest and lightest Boxer-engined sport
bike yet, and it is ready for the road or track.
The BMW HP2 Sport follows in the wake of the successful launch
of the HP2 Enduro (2005) and HP2 Megamoto (2007).
The BMW HP2 Sport is aimed at purist sports riders and is
equipped with many racetrack derived features proven in endurance
racing during 2007.
Some parts, such as the race shift for the close ratio gearbox,
forged alloy wheels and MotoGP inspired dashboard are making their
first appearance in a BMW series production machine.
The BMW HP2 Sport will deliver thoroughbred sports riding on
winding country roads as much as on race tracks.
The highly tuned Boxer engine now delivers in excess of 96 kW
(130+hp) at 8,750 rpm, even more than the R 1200 S launched in
2006. Peak torque is 115 Nm at 6,000 rpm, while the power doesn't
taper until it reaches the lofty red line at 9,500 rpm.
Making the HP2 Sport the highest revving Boxer ever.
Essentially, the BMW HP2 Sport is based on the BMW R 1200 S. But
there are significant mechanical differences, along with a new,
race-ready composite carbon fibre body, race wheels and optional
switchable ABS.
To allow the new HP2 motor to rev so high BMW has evolved a new
cylinder head valve gear design for the double overhead camshaft
layout, now using a drag lever for valve actuation. Bigger valves
are also used. In addition, the double spark plug arrangement used
recently on R series machines has been replaced with a single plug
per cylinder thanks to radially arranged valves that provide a very
compact combustion chamber design.
Further modifications include porting for intake and outlet
flows along with new forged pistons and connecting rods, all of
which help the engine to rev higher and deliver more power.
The compression ratio is 12.5:1 and the engine runs on 98 RON or
above.
A pair of oil coolers is positioned behind the enhanced BMW
kidney grilles in the front fairing.
Externally the engine changes are announced via new carbon
cylinder head covers fitted with easy-to-replace slip pads made
from PA6 hard plastic, an indication of the expected hard cranked
over cornering riding style.
A new stainless steel exhaust system is placed below the engine
for the first time, while the silencer is of a particularly
striking design.
The rerouted two-into-one pipes keep the underside of the bike
clear giving even more clearance for heavily banked high speed
cornering.
Designed to thrill performance riders, the HP2 Sport comes with
a new BMW feature, a race shift that incorporates advanced
electronic control to allow the quickest possible gearshifts.
The standard setting is for the rider to use the gear-shifter
only, to move up the gearbox. By keeping the throttle open and
ignoring the clutch lever, the rider can simply shift up with his
foot. The benefit is quicker shifting and thus faster
acceleration.
Sophisticated electronics automatically sense the up-shift
motion from the shifter and cut the ignition momentarily allowing
the shift to take place when the engine is not under load.
If the rider uses the clutch lever a traditional clutched
up-change is effected. The default mode is race shift for switching
between the six close ratio cogs.
The race shift can also be optionally ordered with a reverse
pattern shift and associated software specifically for competition
use.
This is the first time BMW has offered a race shift for a series
production model.
The BMW HP2 Sport also boasts a sport chassis with fully
adjustable Öhlins shocks front and rear, while a Brembo brakes
set-up employs four-piston radial mounted callipers at the font
grabbing a pair of 320 mm discs. A double sliding piston set up is
used at the rear. Braided steel brake lines are used for optimum
performance.
Given the enhanced performance it was only natural that BMW
engineer a specific and optional switchable ABS system for the HP2
Sport
The BMW HP2 Sport runs on specially developed, weight and
stability optimised, surface-milled forged wheels of 3.5 x 17" and
6.0 x 17".
The forged wheels are fitted as standard with high performance
tyres (120/70 ZR17 front and 190/55 ZR17 rear).
Optimum ergonomics are ensured by the adjustable forged
aluminium footrests, adjustable stock handlebar and radial Magura
clutch/brake levers.
The instrument cluster is all digital and is based on a MotoGP
set-up, delivering the traditional speed and rev information along
with useful race data such as lap times, etc.
Maximising the benefits of the improved power output is a
stringent weight optimisation programme which has seen the wide
application of lightweight composite carbon fibre for the front
fairing and belly pan as well as a simplified rear structure which
has an easily unclipped licence plate and tail light. Thus the BMW
HP2 can be made race-ready in seconds.
The wind-tunnel honed front fairing is stiff enough to dispense
with a subframe, a further weight saving. The front vista is
dominated by lightweight, high-luminosity halogen twin headlamps
with free-formed surface reflectors surrounded by the exposed
carbon fairing and trade-mark kidney grilles which feed air to the
oil coolers.
Thanks to the weight saving programme the BMW HP2 Sport tips the
scales at 178 kg dry, and 199 kg ready to ride.
Rider ergonomics are suitable for both on track riding and
endurance comfort.
Compared with the BMW R 1200 S, the rider sits closer to the
handlebars for a more upright position, behind the 'waistline' of
the fairing.
The slim-line tank is shaped to allow the rider to shift his
weight across the bike when cornering hard.
The BMW HP2 Sport makes its public debut in Paris and is
scheduled to go on sale in 2008.
