traduzione da ADVRIDER del test fatto da un forum tedesco sulla moto che corre nel campionato cross country...

AUGURI!!! :shock:

Did direct german translation from http://enduronet.baboons.de/ - the Cross Country Championship site testing HP2:

Technical:

Technically the HP2 descends from R 1200 gs. Up to the engine
and the electrical system almost all components were however again
developed or modified at least to a large extent. Weight savings as
well as the perfect and compromiseless interpretation on the
requirements of Offroad driving were for the developers completely in
front in the work statement.

Delightfully, but because of the extremely broad spectrum of use the
testing of the HP2 became also very aufwaendig. From the hardest
Endurobetrieb to to the continuous full power on the motorway, from
frosty cold weather to to extreme temperatures, as they occur in the
desert, this vehicle must be able to withstand reliably and
permanently operating conditions, with which probably hardly another
motorcycle in this combination is confronted. The test program, which
beside some test stand tests also tests in, was accordingly extensive
and intensively hot and cold countries as well as Offroad Extremtests
on BMW test areas covered.

The HP2 with their first sport application with Simo Kirssi

The participation in the desert running "Baja California" under
the direction of Jimmy Lewis was likewise part of the total vehicle
and component testing such as continual testings with high speed on
the motorway and on test tracks. Continuous tests in the area in Spain
and in South Africa and the rounded entire program to for the reaching
of production stage off.

Drive
The two-cylinder double-piston engine from R 1200 gs was slightly
raised and achieved by a special application of the motor control in
the performance in connection with the fuel quality superplus (RON 98)
77 KW (105 HP). The max. torque remains unchanged, it amounts to 115
Nm with 5,500 min-1.

Slow driving without jerking without clutch support is not only
because of principle-causes high run culture of the boxers and its
softly using, but sumptuous force development from the "number of
revolutions cellar" possible. Also the thought out, moment-based
engine management of the new box he generation with the automatic
idling regulation contributes to it. Thus the HP2 can particularly
out-play their advantages in difficult passages or with deep soils, on
which spontaneous engine strength is needed, fully.

With view of the main targeted application in the area with the engine
for weight reasons without the balance wave one did. The intake air
snorkel is modified easy and carries a deflector to the protection
from direct splash-water entrance. For the road operation this
deflector can be removed.

The exhaust elbow union was taken over unchanged; the final muffler is
against it one almost 2 kilograms easier reconstruction. The weight
reduction with similar interior structure by be omitted the pipe and
the shorter building method achieved. This becomes possible, because
for the HP2 no suit-cases are intended. In order to avoid a too strong
heating of the suit-cases by the hot exhaust gas stream, otherwise a
certain absorber length is indeed essential.

With the six-course transmission stocks of the intermediate shaft were
adapted and strengthened to the higher loads. The course translation
levels and the other construction correspond to those R 1200 gs. The
construction of the Paraleverschwinge (see paragraph chassis) and the
cardan shaft, which indicate and in the length to the changed rocker
measure were adapted a rubber absorber with other hardness, is
completely new. The secondary transmission of the kardanantriebes
remained unchanged with 2,82:1. The entire drive strand is provided
with a high-quality, magnesiumfarbenen powder coating.

Chassis. The chassis of the HP2 is select a complete new development
using high-quality components. The 25-year old Enduro experience of
BMW motorcycle flowed into the chassis development. In geometry and
the total interpretation of the chassis it applied to master the
spagat between optimal road suitability with high track stability for
the motorway operation and exzellenten Offroad characteristics with
spielerischem handling and large agility.

Framework from the Rallyesport the framework layout is based on the
realizations from the running motorcycles R 900 R, which were used
from 1999 to 2001 factory-installed with the Rallye Dakar and other
international desert running. It concerns a lattice tubing framework
out of steel with more optimally, very homogeneous distributed
rigidity.

Telegabel with track-dependent absorption the front wheel guidance
transfers a telegabel with 270 millimeters spring travel with the HP2
to Upside down building method. Spring travels of this size cannot be
represented with a conventional Telelever construction any longer
meaningfully. The fork has a track-dependent absorption as special
feature; the course and compression phase are multiple and separately
adjustable. The hydraulic system, which prevents a piercing, is
likewise adjustable. The special at this system is - and there is so
only with BMW motorcycle - that the compression phase absorption
remains to a large extent uninfluenced by the adjustment against
piercing. This can be hard "adjusted thus to" can, without thereby the
compression phase absorption within the chief work area of the
absorber becomes substantially tauter.

With a status pipe diameter of 45 the fork the necessary rigidity
achieves and ensures millimeters at the same time a max. steering
angle. The standrohre carry an extremely resistant special coating,
which is still more verschleissfester than the common surfaces on
titanium nitride base.

Innovation during the rear wheel guidance - the pneumatic spring
absorber system. For the rear wheel guidance engineers set
Paraleverschwinge, which was arranged completely new for the new box
he generation as lightweight construction construction further on the
principle of the BMWS. From the effect principle to hardly still
improve, for the HP2 a new interpretation was carried out
nevertheless. The Paralever of the HP2 is longer 30 millimeters than
with the gs. It concerns here a welded structure out of high-strength,
forged light alloy bowls, which also the hardest request of a sporty
Endurobetriebs becomes optimally fair. Exterior flag of the
aufwaendigen reconstruction is the magnesiumfarbene powder coating,
which distinguishes the entire drive strand.

With the shock strut BMW motorcycle sets a character again and
introduces again a highly innovative world novelty in the motorcycle
chassis area. Together with the German company Continental automotives
of system was developed a shock absorber system, which operates
exclusively with air. This pneumatic spring absorber system is with
scarcely 2.3 kilograms approximately 2 kilograms more easily than
conventional constructions, whereby the basic structure and the mode
of operation of the absorption indicate basic analogies. Also with the
pneumatic spring leg a piston drives into an absorption space. Instead
of hydraulic fluid however air is displaced here and led by poppet
valves into a second chamber. The absorption is obtained by throttling
of the air flow. Since air to squeeze together leaves itself
(compressibility) can enclosed air the suspension take over and the
usual steel feather/spring replace.

Air is a medium with ideal characteristics for a shock absorber system
and offers numerous advantages: "natural one" progression of the
spring rate during high load (printing in the system rises). High copy
security (gas law, printing rises with the temperature). "natural one"
progression of the absorption when high demand (viscosity of air rises
with the temperature). Periodical and selective absorption with "more
automatically" adjustment to the loading. Resistance against
overheating (no temperature-dependent leaving of the absorption when
high demand, for example on corrugated sheet runways). Simple
possibility for the adjustment to the loading status. Simple
adjustment of the seat level.

Besides the responsing mode of the suspension and the traction of the
rear wheel are improved by the proportionately smaller ungefederten
masses. The constructional structure of the pneumatic spring leg shows
three consecutively being situated luftkammern, which by air ducts in
connection. An aluminum cylinder forms the two upper chambers, which
are separated by a piston. Enclosed air is compressed by the
longitudinal movement of the separator piston and works thereby as
feather/spring. A defined air volume flows at the same time over
poppet valves (crack choke) into those in each case different chamber
and absorbs by throttling the wheel movement. The lower luftkammer is
formed by gas densities rolling bellows from rubber fabric. It enables
the stroke and seals the shock strut outward, so that no the friction
increasing reciprocating shaft seal is needed. The resistance when
unreeling the rubber bellows over a particularly formed cone completes
the progression of the system.

After outside the shock strut is closed and hermetic. Leakage losses
can become balanced by refill of air over a valve. The filling
pressure variation permits from the outside also a simple adaptation
to that

Seat level by inflating or discharging air. With lowered
seating position however the suspension strut movement reduces, so
that this adjustment offers itself rather for a moderate driving
fashion.

The adjustment to different loading statuses is made likewise very
simply by the filling pressure. A fine detail in addition: From a
small "spirit level" at the tail framework the normal position of the
motorcycle can be read off, whereby the adjustment is facilitated. For
inflating on the way a hand high-pressure pump with manometer is
provided in series, which can be used naturally also for the
reinflating of the tires after an air pressure sinking in the area.

The possibility of a frequency-selective absorption with the pneumatic
spring absorber system, which is carried out by a direct tuning of the
internal flow system together with the crack chokes, is singular. An
important effect attainable thereby is those substantially better
traction of the rear wheel on wavy background. The absorption can be
laid out and adapted in the frequency ranges of the rear wheel
oscillation lively of surface irregularities directly in such a way
that the wheel follows the unevenness after ideal way and keeps
optimal soil contact. That results in better propulsion in the case of
hard accelerating and concomitantly more driving fun and at the same
time more security in the case of braking.

Piercing the suspension, as it occurs during long drawn bumps and high
load frequently, is excluded likewise to a large extent by the
"natural" spring rate adjustment of the pneumatic spring as well as
the frequency-selective absorption. The basic characteristic of the
absorption can be adapted additionally over a Handraedchen, which
releases a bypass drilling in the absorber, in two levels between
comfort-oriented road adjustment and taut area adjustment.

At the edge it is marked that when collapsing the HP2 "from hand" and
in the status a misleading impression develops from the absorption
effect, because the resulting movement does not correspond to driving
in rate and frequency.

A not insignificant advantage of the system is also in the complete
insensitivity of the shock strut to any dirt due to the closed
building method. Also in the finest desert sand there is therefore no
more wear of seals and guidance.

The HP2 of cross wheels with spokes, which showed up in all tests also
hardest demands grown, possesses cross wheels with spokes for the
Offroad application in the 21''-Format for in front according to the
Offroad interpretation. For large clearance and optimal guidance the
front wheel has the dimension 1,85' ' x 21. In the back the wheel size
amounts to 2,5' ' x 17. Tubeless tires are drawn up in series. Under
the imported designation "Karoo" developed the company Metzeler as
well as BMW motorcycle particularly for the HP2 a completely new high
speed all-terrain tire in the dimensions 90/90 21 in front and 140/80
17 in the back, which grew the high request of the machine as well as
its performance and Geschwindigkeitspotenzial.

As option there are Motocross similar tires with a high negative
profile proportion for the predominant area application. These tires
certified for the road are likewise a joint development of BMWS
motorcycle and Metzeler special for the BMWS HP2.

For the area operation also tires with hose and thus different
profiles can be used. The rear wheel is in series with a second valve
drilling provided and with it prepared for the use of tire holding
(option) for driving with lowered air pressure. The second valve
drilling is locked when tubeless tyre with a second tire valve.

Weight-optimized brakes the brake assembly of the HP2 out by
first-class braking action to be dosedness draws and purifies. In the
front wheel an a disc brake with schwimmsattel is used. "semi
swimming" the stored brake disk with 305 millimeters of diameters is
thick for weight reasons of only 4.5 millimeters. In the back the a
disk brake calipers brake from R 1200 gs with a disk diameter of 265
millimeters operates. The brake hoses are only in front steal-encased.
For the rear wheel brake one requires oneself for a Enduro rather a
softer pressure point, therefore consciously a conventional rubber
fabric brake hose is used here.

For the introduction on the market the HP2 without ABS is offered.

Tank, seat, control elements and attachments with the organization of
tank, seat and control elements were the ergonomic request of the
Enduroeinsatzes, with which much is driven in being, in the
foreground.

The fuel tank of the HP2 is completely new, it is embedded into the
space between the upper crossbars. Impacttough and halftransparent
plastic (high-interlaced polyethylene) is the optimal and light
material for the fuel tank, which is taken off by an easy
Kunststoffcover. The capacity amounts to 13 litres. By the window in
the Cover the fuellhoehe remains from the outside visible; contents
can be measured by two scaling lines sufficiently exactly. One refuels
in the area application from cans, this possibility of reading is from
the outside more practical than an electrical display. This besides
because of constant change of position in the area operation would
display only inaccurately. A reserve flare is however further
available.

In order to ensure an optimal vehicle guidance also in being, to a
slim framing and vehicle outline in the transient area from the tank
to the seat one paid attention. The two-colored seat is particularly
in the front area narrowly cut, and this narrow line draws itself into
the tank area.

The absolute geometrical seat level for the driver amounts to 920
millimeters (step length of curve 1920 mm) when desired and with that
(option) available low seat of 900 millimeters.

The steering wheel attachment is one intelligently thought out
construction. Asymmetrically bored steering wheel clamp stands permit
a non-standard position of the broad steering wheel in two different
positions.

If one the clamp stands 180 degrees, then the longitudinal position of
the steering wheel shifts itself 20 millimeters. The steering wheel
consists of aluminum and is konifiziert to the ends. Special attention
was put on a large steering angle. It amounts to to the right and on
the left of 42 degrees each, which the agility increased and a safe
vehicle control enables also with extreme creep speed.

The fussrasten made of stainless high-grade steel are broadly executed
for a safe status with most different foot positions. The Clou in this
connection is a hinged spacer piece at the brake pedal, with which the
position of the lever can be changed to the foot without tool rapidly
and simply. Whether when driving in being or in sitting - the brake
lever is so in each situation optimally attainable. This of BMW by the
way did not patent mechanism changed the position of the brake lever
to the brake cylinder, so that the necessary and correct
"Schnueffelspiel" is preserved despite the adjusting possibility.

Electrical connection, electronics and instrumenting the innovative
electrical system with CAN bus technology (CONTROLLER AREA network)
one took over unchanged by R 1200 gs. The small cable expenditure
opposite conventional electrical systems, be omitted classical fuses
and the full diagnostic ability are favourable also for the
Enduroeinsatz. Favorable is also the small weight.

The integrated electronic going away barrier (EMS) is standard and
operates on the basis of an exchange of coded and variable data
between vehicle key (transponder) and on-board electronics.

This technique is the at present best and safest for a going away
barrier. Instrument combination concentrates likewise on the
substantial. It does without a tachometer. A speedometer and a info.
Flatscreen are sufficient for the requirements of the area driver. In
the technique it corresponds to that R 1200 gs. As additional display
the operation hours are callably, important for to change interbarrier
of the air cleaner with predominant Offroad application on dusty
runways.

Design and body the Design of the HP2 are extremely puristic and
orient themselves at the functionality of the components. The
reduction on the substantial is even also in the body area a
consciously used style item. Only the tank cover and a part of the
fender are painted.

Plastic parts within fall-endangered areas as for the example the tank
side parts and the front fenders consist of through-colored, grained
plastic without additional lacquer job, so that scratches are hardly
visible and do not step out. The HP2 is offered exclusively in the
colour Indigoblau metallic/Alaskagrau.

An example of high functionality is the headlight mounting plate. It
is executed extremely stable and serves so at the same time as handy
platzierter mountain handle. Also within the tail area are grip
recesses under the seat, which are so arranged that they are
effectively protected forwards by the rear wheel raised dirt.

The flag carrier and the turn signals are problem-free dismantlable
for the area operation over five screws, the cables over a patch cord
are separated.

Protecting attachments for the Offroad application standard each HP2
with a package with additionally protecting components is delivered to
the subsequent cultivation. This protection package covers: Hand
treads, which minimize the danger of injury by their open building
method with falls. A wide plastic protective relay for motor, which
fall-caused damages within the area of the cylinders and at the
butterfly valve connecting pieces reduced. A transparent plastic disk
for the assembly before the headlight, which is to prevent destroying
the headlight glass by whirled up stones. This component is not
certified for public roads. A rear axle protection, which reduces the
danger of a damage of the final drive housing when putting on stones.
A "Brake Snake in such a way specified". This small steel cable within
the area of the brake pedal is to prevent that stones, branches or
other articles between brake pedals and engine to wedge and bend,
block themselves the lever or to operate and with it an inadvertent
braking to cause.

Label name

A new label name and a new model designation: "HP" is the
contraction for "High performance". Of the "2" these Enduro sporty in
the model designation indicates the two-cylinder double-piston engine.
The term "High performance" or "high speed" is sense-figurativy for
the sporty performance thought, the efficiency of the entire vehicle
and not only on one side for a higher engine performance. "High
performance" - which is the skillful tuning of all individual
components in the view to a convincing whole, which represents more
than the total of individual factors. It is the synonym for one
thought out total conception and perfection in detail, for superior
handling characteristics and pure, clear driving fun. HP is naturally
also for the prestige, which is connected with a particularly
high-quality vehicle. The HP2 is the first representative of a new,
independent motorcycle category of BMW. Boxer models are located in
the focus. HP motorcycles use the technical base of series vehicles,
differentiate themselves however clearly by a compromiseless
interpretation on its respective targeted application, by its clear
and very consistent sport orientation and exclusive product features.

These special motorcycles beyond the usual structures, like that as it
for the larger series meaningfully are, in small teams developed by
professionals with passion. The special team structure upon very
efficient operational sequence guarantees that the experience of many
years of the developers, their feeling for the substantial, its
personal know-how and it "Feeling" not filtered into the product flow.
These engineers avail themselves at the same time however of the most
modern development and simulation tools as well as all technical
possibilities, which BMW has to offer altogether.

This symbiosis from Hightech and feeling relating to crafts is it,
which constitute the singular attraction of the HP motorcycles. High
performance motorcycles of BMW are somewhat completely special
therefore, it are exclusive and authentic and comparatively RSR will
remain. The quotation results from the outstanding total
characteristics, the substantially higher product substance and the
comparatively low numbers of items.

On the fahrerischen requirements of the customers and the abilities of
the HP2 co-ordinated, exclusive training supplies and fascinating
Offroad journeys are special in preparation and the supplies around
the new High performance concept gradually will approximately
complete.
