BMW Announces Availability of the HP2 Sport in
the U.S.A.
May 9, 2008 - The BMW HP2 Sport has arrived at
U.S. BMW motorcycle retailers. The same
high-performance sport bike that Richard Cooper and
Brian Parriott rode to fifth and sixth place
finishes in last month's Daytona 200 is now
available in limited supplies for serious motorcycle
enthusiasts. The high-performance (HP) two
(2)-cylinder Boxer -- customized to meet the
requirements of the ambitious sport rider -- has a
manufacturer's suggested retail price of $25,375
(excluding taxes, license, options, and handling
The sportiest, most powerful and lightest Boxer
ever manufactured, the HP2 Sport features numerous
exclusive details, previously restricted to racing,
that were never before seen in series production
vehicles. Technology such as the
self-supporting and aerodynamically optimized
fairings made completely of carbon fiber, the quick
shifter, a dashboard similar to that used in the
MotoGP, the forged aluminum wheels and brakes with
radially bolted calipers make the HP2 unmistakably
athletic on both country roads or the racing
The most striking difference between the BMW HP2
Sport from the earlier 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 those on the
BMW R 1200 S.
Further modifications, such as the flow-optimized
intake and outlet, new forged pistons and adapted
connecting rod, help the engine to achieve the
necessary higher output compared to the basic
engine. A new stainless steel exhaust system
is placed below the engine for the first time,
keeping the lower area of the motorcycle extremely
slim for greater freedom of movement for a &hanging
off& riding position.
Although designed for racing prowess, the BMW HP2
Sport does not forego the safety benefits of ABS.
A sophisticated anti-blocking system, specially
adapted to the HP2 Sport, is available as an option
and is configured so that it can be deactivated for
the racetrack.
Following the BMW Motorrad Motorsport design, the
HP2 Sport features white lacquering on the
windshield, rear, mudguard and side cover. The
engine spoiler carries the two-tone &HP2&
and the lattice frame and wheels are lacquered in
the BMW Motorrad color of Motorsport Blue.
BMW Announces Pricing for the HP2 Sport
February 9, 2008 - Boxer fans, reach for your
checkbooks!& The BMW HP2 Sport, arriving soon
at US BMW motorcycle retailers, will have a
manufacturer's suggested retail price of $25,375
(excluding taxes, license, options, and handling
charge) and a destination charge of $495.

1. Concept, Requirements and Features
The dream of many Boxer fans has come true: With the
new 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 optimized fairings made completely
of CFK, the gear shift assistant, a dashboard like
that used in the MotoGP, the forged aluminum 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 hp at 8750 min–1
compared with the significantly modified engine of
the BMW R 1200 S. The maximum torque lies at 115 Nm
at 6000 min–1, the highest revs of the engine
reaches a peak value at 9500 min–1.
Technically, the BMW HP2 Sport is based on the
BMW R 1200 S. Customized 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 long-distance 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 flow-optimized
intake and outlet, new forged pistons and adapted
connecting rod help the engine to achieve the
necessary higher output compared to the basic
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
6-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 aluminum footrests, the adjustable stock
handlebar and the Magura brake levers with radial
mounted brake actuators. 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 (see Chap. 3).

Attention was paid consistently to the
lightweight construction of all components.
This includes not only the self-supporting front
fairing and the likewise self-supporting carbon rear
or the weight-optimized 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 favorable 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
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.
The market introduction of the BMW HP2 Sport is
scheduled for 2008.

2. Model Designation and Marque
“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 thought-out 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
These exceptional motorcycles are developed with
great passion by small teams of professionals. The
special team structure guarantees that the many
years of experience of the development engineers,
their grasp of the essential, personal know-how and
“feeling” have a direct influence on the product.
At the same time these engineers make use of the
most modern development and simulation tools plus
all the technical facilities that BMW as a whole has
to offer. This symbiosis of high-tech and
professional skill is what distinguishes the unique
appeal of the HP motorcycles.
That’s why high performance motorcycles from BMW are
so they are exclusive and
authentic and will remain greatly sought after.
3. Development, Technical Highlights and
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 dedicated specialist team of veteran racing
motorcyclists, engineers and mechanics, whose pulse
quickens for the Boxer and who have also devoted
themselves to motor sport in their private lives,
developed this new model
for BMW Motorrad. Experiences that the BMW Motorrad
motor sport team
had collected with the Boxer racing motorcycle –
including a number of races
in the endurance world championship of 2007 – were
also incorporated.

DOHC cylinder heads, valve actuated by drag
A complete redesign of the cylinder heads allowed
the Boxer to reach higher revs. Extensive 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–1.
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
millimeters (intake) and from 31 to 33 millimeters
(outlet) respectively.
The intake channels were
machined for optimization. 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.
High-strength and lightweight forged piston
The bore and stroke ratio is unchanged in the HP2
Boxer. The high-strength, weight-reduced forged
piston and the correspondingly adapted conrod
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–1 and a maximum torque of over 115 Nm at
6000 min–1.
Flow through two parallel and consecutively
switched oil coolers
So that the Sport Boxer operates well under all
conditions from the thermal aspect, two oil coolers
positioned one after the other and with a parallel
flow-through are deployed.
Wind tunnel optimization
of the BMW ‘kidneys’
in the front fairing ensures an effective flow
through the double oil cooler.
Stainless steel exhaust system with active
exhaust gas flap
For the first time the 2-in-1 exhaust system made
completely from stainless steel is placed under the
oil sump. This configuration guarantees optimum
angles of tilt when riding. An exhaust flap in front
of the double exhaust pipe silencer at the rear and
actuated by an electronically controlled servomotor
via cable produces a fuller torque curve.
A fully-controlled catalytic converter cuts exhaust
gas emissions. Oxygen sensors in the two header
tubes monitor the oxygen level and guarantee an
optimum air-fuel ratio over the entire torque band.
An example of the great attention to detail that
characterizes both the development and production
of the BMW HP2 Sport is the exhaust pipe fixtures on
the single-piece, self-supporting carbon rear. These
are thermally decoupled while, at the same time,
compensating for the change in length of the exhaust
system during warming and cooling.
The hump also
boasts sophisticated ventilation openings, used to
effectively deflect the heat away from the underseat
exhaust. Additional features of the exhaust system
are the highly attractive design
and the impressive Boxer sound that escapes from the
high-volume silencer.
Close-ratio six-speed gearbox
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
racing feature that benefits the dynamic driving
characteristics.
Straight from the racing world: Gearshift
A further pedigree racing detail is the standard
gearshift assistant of the
BMW HP2 Sport, also described as an automatic
gearshift. The system allows rapid gear change
without reducing the gas or using the clutch. If the
lever is activated, the electronic engine control
throttles back the ignition angle and reduces the injection.
This means the power
unit is at “low load” for the gearshift so it is
possible to change gear rapidly without needing the
The gearshift assistant operates under normal riding
conditions and, on request, for racing with an
inverted switching scheme (pressure sensor as
special equipment).
However, if the rider actuates
the clutch, the system remains inactive. The BMW HP2
Sport therefore always leaves the decision
of whether or not the gearshift assistant is
deployed to the driver.
Modified frame construction
The steel tube mid-frame comes from the BMW R 1200 S,
but was adapted
to the new single-piece and self-carrying carbon
fiber composite rear
in the area around the location points.
Telelever with ?hlins sport spring strut
The front wheel suspension is provided by the
stable, approved telescopic
lever construction. Its trailing link is supported
by a specially tuned ?hlins sport spring strut with
compensating tank, adjustable in tension and
compression stroke damping as well as in the spring
pre-tension.
The expanded surface around the slider
clamping device in the lower fork brace allows fine
adjustment of the vehicle height.
Quality components made of milled aluminum
The upper fork brace and the two adjustable
high-quality stock handlebars flange-mounted in the
crankshaft throw are made from fully milled, forged
aluminum parts. The main brake cylinder and the
clutch master cylinder
with radial pump coupling fixed by quick-release
clamping calipers usually
found in racing are also used here.
EVO Paralever with ?hlins sport spring strut
The Paralever rear wheel suspension also
originates from the BMW R 1200 S, but in the BMW HP2
Sport it has an ?hlins sporting spring strut with
compensating
tank adjustable in all aspects. Thanks to the
longitudinal adjustment integrated in the spring
strut the vehicle height can also be varied at the
This means the chassis geometry of the BMW HP2
Sport can be individually optimized for different
racing circuits.
Every BMW HP2 Sport is supplied as standard with an
exclusive toolset which can be used to make all
settings on the chassis components.
Exclusive forged wheels and racing tires
The BMW HP2 Sport runs on specially developed,
weight and stability optimized, surface-milled
forged wheels of size 3.5 x 17” or 6.0 x 17”.
These are considerably lighter than conventional
die-cast wheels, but have comparable high stability. The handling
characteristics benefit enormously
from the smaller rotating masses. The sports Boxer
is really easy to steer on bends and allows
incredibly rapid change of direction.
The forged wheels are fitted as standard with sports
tires in 120/70 ZR17 format at the front and 190/55
ZR17 at the rear. These tires from renowned
manufacturers – generally used only on the racing
circuit such as the Supersport championship, for
example – are homologated for use on asphalt road
surfaces. The engineers decided on a 55 series
cross-section
as this achieved the best results for the overall
characteristics in tests.
Brembo monoblock racing brakes
The braking system of the new BMW HP2 Sport also
presents itself as uncompromisingly sporty. Single-piece, radially mounted four-piston brake
calipers from Brembo that hold the two
320-millimetre discs powerfully
in its grip are used on the front.
The radial screw
connection is effected by a new die-cast foot on the
lower part of the Telelever. A double sliding piston
decelerates the rear wheel. It goes without saying
that the hydraulic application of the brake calipers
is activated by high-quality, steel armored brake
Modified, switchable BMW Motorrad ABS is
BMW Motorrad offers an ABS adapted to sporting
events as an option. The function of the system has
been optimized to prevent the rear wheel from
An additional pressure sensor in the front
brake circuit provides sensitive regulation of the
system and the control unit prevents the front wheel
brakes from opening too early when the load on the
rear wheel is greatly reduced. Nevertheless the ABS
can be deactivated for racing events.
Racing ergonomics
Even at the outset of the development, the engineers
focused on the
seat position. Compared to the BMW R 1200 S, the
rider moved closer
to the handlebar resulting in a notably more upright
seat position oriented towards the front wheel and
behind the ‘waistline’ of the fairing.
importantly, the remarkably slim design of the tank
area favors the rider’s weight displacement
(hanging off) on the racing circuit.
The BMW HP2 Sport also benefits here from the
experiences gained
in long-distance races where it is not only a
question of speed, but also
of staying power. Because the rider finds a
suitable, but comparatively
relaxed, riding position for racing, the new BMW
Sport Boxer offers
genuine endurance qualities.
Adjustable footrest system
The range of high-grade racing components includes
the adjustable footrest system made of milled,
high-strength aluminum. An eccentric cam is used
to adjust the height of the footrests and to move
them forwards or backwards.
Stepped setting
positions of the footrests make sure that identical
adjustment is possible on both sides. At the same
time, the likewise fully adjustable brake and gear
lever allow optimal positioning of the operating
Adjustable stock handlebar and Magura manual
Also the stock handlebar of milled forged
is ideally positioned and can be adjusted by
changing the offset. The Magura radial manual
controls allow manual lever width setting of the
brakes and clutch.
All Carbon fiber composite fairing
All the fairings of the BMW HP2 Sport are made from
carbon where the single-part rear as well as the
front fairing are realized as self-supporting
elements. The latter has a noticeably slimmer
construction than the BMW R 1200 S and houses
lightweight, high-luminosity halogen twin headlamps
with free-formed surface reflectors. Special details
include the number plate carrier of the
BMW HP2 Sport: It can be removed along with the tail
lamp and indicators
in a few easy steps before taking part in a race.
Refinements in the wind tunnel
Like every BMW Motorrad the new BMW HP2 Sport was
also given its
finishing touches in the wind tunnel. Not only were
components such as the windshield and new rear-view
mirror optimized from a the
engineers also paid particular attention to the airflow
for cooling the engine.
So the front spoiler guides the air stream
specifically towards the outlet side of the cylinder
heads while the BMW ‘kidneys’ in the front fairing
guarantee an effective flow of the double-oil
cooler. Lastly, elaborate ventilation openings in
the carbon tail ensure that the heat of the underseat exhaust system is efficiently deflected.
Sports info centre: GP dashboard from 2D
A real highlight for all racing enthusiasts is the
production-line dashboard in the cockpit of the BMW
HP2 Sport. It was developed in collaboration with
the acclaimed company 2D Systems that also deploys
its systems in GP racing for data recording and
The system has a large, easily readable
digital display and works in different modes. It is
operated by two switches on the left handlebar
In road mode the rider can view typical information
such as revs, speed,
time, kilometers, remaining distance and driving
time on the display and is shown supporting
information during the warm-up phase of the engine.
In race mode the screen provides data about
circuit times, maximum revs,
top speed or number of gearshifts, for example. The
stored data can also be read out with a laptop. In
addition there are eight freely programmable LEDs
in the upper area of the dashboard that can be used
as a rev display or
external gearshift light.
Like the other functions,
the displays are also freely programmable.
Finally, the GP dashboard offers a large number of
expansion options.
A lap timer with transmission/receiving unit, GPS
tracking or datalogger can
be connected to a free input.
Following the BMW Motorrad motor sport design
fairing of the new HP2 Sport is realized to a large
extent in carbon-look
