2010 BMW HP2 Sport
BMW Motorrad has announced details of
its sportiest, most powerful and lightest signature
Boxer series of all time. The third model of the High
Performance HP range has been designed for the ambitious
sports rider and features numerous exclusive details
that were previously restricted to racing –
some making a first appearance on a production motorcycle.
Examples include the self-supporting
and aerodynamically optimised fairings made completely
of CFK; the gear shift ‘assistant’; a
dashboard like that used in MotoGP; forged aluminium
wheels and racing brakes with radially-bolted calipers.
Wherever the eye looks, it sees pure racing technology.
It is unmistakably dynamic and agile – a machine
that will inspire on country roads and race circuits.
BMW Motorrad deliberately decided to
further develop the historic boxer engine for road
racers with racing circuit intent. The key engine
data is extremely good, for example, the engine achieves
more than 96kW / 128bhp at 8750 min–1 –
more than the significantly modified engine of the
BMW R 1200 S. The maximum torque of 115 Nm is achieved
at 6,000 min–1, while the highest engine revs
reach a peak value at 9,500 min–1.
Technically, the BMW HP2 Sport is based
on the BMW R 1200 S. Although customised to meet the
requirements of the ambitious sports rider down to
the last detail, the BMW HP2 Sport is a completely
independent and exceptional motorcycle. Many detailed
solutions are based on the experiences gained in long-distance
The most striking difference of the
BMW HP2 Sport (compared with the endurance racing
boxer) is the all-new cylinder heads: Each of the
double overhead camshafts (DOHC) uses a drag lever
to actuate the valves that are larger those on the
BMW R 1200 S. Further modifications such as the flow-optimised
intake and outlet, new forged pistons and adapted
connecting rod help the engine to achieve the necessary
The striking design of the rear silencer
is impressive and 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 to be kept extremely slim, enabling greater
freedom of movement for riding techniques such as
The inimitable boxer sound has a new acoustic quality
and is generated by the exhaust system. In addition,
the fitting of a CFK engine spoiler also provides
Another exclusive racing feature is
the gearshift assistant. Together with the close ratios
of the 5-speed gearbox it enables fast gear shifts
without having to ease off the throttle and operate
the clutch. This technology is offered for the first
time in a series motorcycle. In order to adapt the
gearshift pattern for the racing, a suitable replacement
pressure sensor is available as special equipment
The fully adjustable Öhlins sports
chassis also has a Brembo monoblock brake system with
radially-mounted, four-piston fixed calipers at the
Optimum ergonomics are ensured by the
adjustable forged aluminium footrests, adjustable
stock handlebar and the Magura radial manual buttons.
The instrument console is directly
from MotoGP and provides the rider with important
information such as lap times, other racing data and
the usual displays (see chapter 3). Consistent attention
was paid to the lightweight construction of all components.
This included the self-supporting front fairing, the
self-supporting carbon rear, the weight-optimised
forged wheels, and such hidden details as the lightweight
generator. It was therefore possible to reduce the
unladen weight of the HP2 Sport to DIN standard with
a full tank (90%) to 199 kilos. The dry weight is
only 178 kilos.
The interplay of variable ergonomic
design, increased engine output, and the favourable
centre of gravity of the boxer engine guarantees superb
handling and racing potential. Even if racing is clearly
at the forefront of the BMW HP2 Sport, it does not
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 that it can be switched off for the racetrack.
The market introduction of
the BMW HP2 Sport is scheduled for 2008.
Model designation and marque
HP is the abbreviation for ‘High
Performance’ and the ‘2’ in the
model designation of the supremely sporty BMW refers
to the two-cylinder boxer engine. The term ‘High
Performance’ stands for sporting performance
and the achievement potential of the entire machine.
‘High Performance’ also reflects the skilful
harmonization of all individual components into a
convincing whole. It is the synonym for a well thought-out
overall design and perfection right down to the last
detail. It embodies the very best driving characteristics
and pure, unadulterated riding pleasure. HP also stands
for the prestige connected with an exceptional high-quality
and exclusive machine.
After the HP2 Enduro and the HP2 Megamoto,
the HP2 Sport is the third model of an independent
motorcycle category equipped with the historic boxer
engine. All HP2 motorcycles use the technical basis
of production machines but are clearly differentiated
by an uncompromising interpretation of their prime
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 essential personal know-how and ‘feel’,
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. This symbiosis of high-technology and professional
skill is what defines the unique appeal of the HP
High performance motorcycles from BMW
are invariably something special; they are exclusive
and authentic and will remain greatly sought after.
Development, technical highlights
The new HP2 Sport extends the HP model
range of BMW Motorrad and is a descendant of the R
1200 S. Apart from established concepts such as the
BMW Motorrad Telelever, EVO Paralever and the cardan
shaft drive, almost all components were newly developed
or at least extensively modified. Weight saving, increased
performance and the uncompromising sporty configuration
was a top priority in the list of requirements for
the development engineers.
A dedicated specialist team of veteran
racing motorcyclists, engineers and mechanics, developed
the new model for BMW Motorrad. Experience that the
BMW Motorrad motor sport team had acquired with the
boxer racing motorcycle – including a number
of races in the Endurance World Championship of 2007
– was also incorporated.
DOHC cylinder heads, valve
actuated by drag lever
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 a 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). 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
control an intake and outlet valve and the cams are
conically ground. For a higher gas flow, the valve
plate diameter was increased from 36 to 39 millimetres
(intake) and from 31 to 33 millimetres (outlet). The
intake channels were also 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.
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 corresponding 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 96kW / 128 bhp at 8,750 min–1
and a maximum torque of over 115Nm at 6,000 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 optimisation
of the BMW ‘kidneys’ in the front fairing
ensures an effective airflow through the double oil
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 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 emits 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. This configuration is also a typical
racing feature that benefits the dynamic driving characteristics.
Straight from the racing world: the gearshift ‘assistant’
A further 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 shutting the throttle or using the
clutch. If the gear 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 clutch.
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 operates 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 rider.
Modified frame construction
The steel mid-frame tube comes from the BMW R 1200
S but was adapted to the new single-piece and self-carrying
CFK rear in the area around the location points. Telelever
with Öhlins 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 Öhlins
sport spring strut with compensating tank, adjustable
in tension and compression stroke damping, as well
as 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 aluminium
The upper fork brace and the two adjustable high-quality
stock handlebars flange-mounted in the crankshaft
throw are made from fully milled, forged aluminium
parts. The main brake cylinder and the clutch master
cylinder with radial pump coupling, fixed by quick-release
clamping callipers, usually found in racing are also
EVO Paralever with Öhlins sport spring
The Paralever rear wheel suspension also originates
from the BMW R 1200 S, but in the HP2 Sport it has
an Öhlins adjustable sporting spring strut with
compensating tank. Thanks to the longitudinal adjustment
integrated in the spring strut the vehicle height
can also be varied at the rear. This means the chassis
geometry of the BMW HP2 Sport can be individually
optimised 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 tyres
The BMW HP2 Sport runs on specially developed, weight
and stability optimised, surface-milled forged wheels
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 easy to steer on bends and allows
incredibly rapid change of direction.
The forged wheels are fitted with sports tyres as
standard in 120/70 ZR17 format (front) and 190/55
ZR17 (rear). These tyres from renowned manufacturers
– generally used only on the racing circuit
such as the Supersport Championship – are homologated
for use on asphalt road surfaces. The engineers decided
on a 55 series tyre cross-section as this achieved
the best results, when testsing, for the overall characteristics.
Brembo monoblock racing brakes
The braking system of the new BMW HP2 Sport is also
uncompromisingly sporty. Single-piece, radially mounted
four-piston brake calipers from Brembo powerfully
hold the two 320-millimetre discs at 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, and the
hydraulic application of the brake calipers is activated
by high-quality, steel armoured brake lines.
Modified, switchable BMW Motorrad ABS (on
BMW Motorrad offers ABS adapted for sporting events
as an option. The function of the system has been
optimised to prevent the rear wheel from lifting.
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.
Even at the beginning of development, the engineers
focussed on the seat position. Compared with 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. More importantly, the remarkably slim
design of the tank area favours the rider’s
weight displacement (when hanging off) during races.
The BMW HP2 Sport also benefits 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
aluminium. An eccentric cam is used to adjust the
height of the footrests and to move them forwards
or backwards. The stepped setting positioning of the
footrests make sure that identical adjustment is possible
on both sides. At the same time, the fully adjustable
brake and gear lever allow optimal positioning.
Adjustable stock handlebar and Magura manual
The stock handlebar of milled forged aluminium is
ideally positioned and can be adjusted by changing
the offset. The Magura radial manual controls allow
manual lever width setting of brakes and clutch.
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 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: In just a few easy steps, before
taking part in a race, the carrier can be removed
along with the tail lamp and indicators
Refinements in the wind tunnel
The new BMW HP2 Sport was given its finishing touches
in the wind tunnel. Components such as the windscreen
and new rear-view mirror were optimised aerodynamically.
The engineers also paid particular attention to the
airflow for cooling the engine. The outcome was that
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 instrument panel 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 analysis.
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 riding mode the rider can view typical information
such as revs, speed, time, kilometres, 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.
The stored data can also be read with a laptop. In
addition, there are eight freely programmable LEDs
in the upper area of the display that can be used
as a rev read-out or external gearshift light. Like
the other functions, the displays are also freely
Finally, the GP dashboard offers a large
number of expansion options.
A lap timer with transmission/receiving unit, GPS
tracking or data logger can be connected to a free
Following the BMW Motorrad motor sport design The
fairing of the new HP2 Sport is realized to a large
extent in carbon-look and follows the style of the
BMW Motorrad motor sport design with white lacquering
on the windscreen, rear mudguard and side cover. The
engine spoiler carries the two-tone HP2 lettering.
The lattice frame and wheels are lacquered in the
BMW Motorrad colour, Motorsport Blue.
