New BMW Adventure Bike Expected to Arrive at
Retailers This Fall
January 25, 2008 - BMW Announces F 800 GS
Motorcycle enthusiasts eagerly awaiting the arrival
of BMW's new F 800 GS will need to be a bit more
patient, as production of the middleweight
dual-purpose enduro will be delayed due to worldwide
demand for the popular F 650 GS. The F 800 GS
is now expected to be available at U.S. BMW
Motorcycle retailers in the Fall 2008, making it a
In the meantime, prospective owners may also want
to consider the 2008 BMW Motorrad GS line, which
features the upgraded
1200 GS Adventure models, which will arrive in
dealerships this Spring.
The 2008 BMW R 1200 GS features a new aluminum
handlebar which can be mounted in two positions and
which offers increased ergonomics, making its seated
(or standing while off-road) position even more
comfortable. Its engine offers 5% more power
and its new transmission ratios also mean quicker
acceleration and better low-speed traction.
The R 1200 GS Adventure, named "Best Adventure
Bike" three years in a row by editors of
Motorcyclist Magazine, also offers a number of
significant features that make it even more adept at
riding to the ends of the earth.
In addition to new design elements, including
two-part, two-color hand protectors, the new 2008 R
1200 GS Adventure provides a taller windshield,
adjustable seat and extra wide foot pegs making long
days in the saddle both comfortable and enjoyable.
An 8.7 gallon fuel tank allows the rider to cover
vast areas of territory easier and optional ABS
enhances braking safety when required.
The most significant technological development
found on both the 2008 R 1200 GS and GS Adventure
models is optional enduro ESA (Electronic Suspension
Adjustment) technology (a first-time offering for
BMW off-road bikes) with three damper settings --
Sport, Normal and Comfort -- giving riders the
option of customizing both front and rear
suspensions to his or her specifications.
Motorcycle enthusiasts got a preview of all three
new GS models at Cycle World IMS shows this winter.
1. Concept and Background
The heavily rumored and long-awaited F 800 GS is
a new Adventure Touring or Enduro model in the
BMW Motorrad lineup. BMW is presenting the
motorcycle as "a worthy
successor to the totally successful F 650 GS with
its single-cylinder engine". In typical BMW
fashion, the bike is completely ready to go and can
be outfitted with a huge number of accessories,
The new bike is claimed to be
with its sturdy appearance reminiscent of the very
popular BMW R 1200 GS and its features like long spring travel,
indicate what it can do off-road. The signals
gives off are clear yet diverse: fun to ride on the
street and stamina on journeys even when the destination can only be reached by gravel tracks.
And guess what? It has a chain
BMW claims a high level of stability combined with playful
handling are features for the new F 800 GS, along
with a strong chassis and
impressive engine performance for maximum riding
The inline two-cylinder engine comes from the
well-known F 800 model series, but beyond this, the
F 800 GS has been completely redesigned. A
completely new frame and new wheel suspension with
new spring-shock absorber elements are used, for
example, which, BMW claims, "will surpass the expectations of even
the most demanding Enduro riders."
The belt drive and
single-strut swing arm of the F 800, which are ideal for pure
on-road use, have been replaced by a light chain
drive, which, in combination with a very stable,
attractive aluminum profile double-strut swing arm
offers particular advantages in off-road riding in
particular. The new GS is thus not only in its
element on roads – it can also always find a way
BMW said that the bike "thus
combines the two worlds in a way that has never
before been achieved in this class and offers the
maximum possible freedom in terms of its areas of
use." They have positioned the dynamic
Adventure-Tourer at an attractive price, and our
guess is that it will be an extremely popular

rugged on- and off-road motorcycles.
model offers the typical qualities of an Adventure-Tourer
-- on- and off-road performance and capabilities. While large-capacity
sometimes reach their limits because of their weight
and overall design, the new F 800 GS is different,
according to BMW.
The overall package combines balanced
power and weight, excellent ground clearance, long
spring travel, precise wheel guidance and
sophisticated ergonomics, giving excellent off-road
riding and excellent long-distance performance.
The chassis combines all the ingredients that a real
Enduro needs: a sturdy steel tube frame that allows
a steering lock of 42 degrees, a rigid upside-down
fork with 230 mm spring travel, a sturdy aluminum
double-strut swing arm with a path-dependent
cushioned spring strut and 215 mm spring
travel and solid wire-spoked wheels.
A 21-inch front
wheel in the classic Enduro dimensions of 90/90-21
should provide running stability in slow off-road riding,
while the rear wheel's dimensions of 150/70-17
ensures that the engine power is always transferred
securely to the track.
The engine is the parallel twin from the F 800 S
modified for the new usage, with its cylinders now
only inclined 8.3 degrees forward. The strong,
liquid-cooled four-valve two-cylinder is
particularly convincing because of its spontaneous
response, its impressive torque and its low fuel consumption.
Nominally, the engine provides 85 HP
at 7,500 RPM and at 5,750 RPM it sends
61 pounds-feet of torque to the sliding bearing based
Thanks to the regulated three-way
catalytic converter and secondary air system, the
twin also releases its power in a way that is environmentally friendly.
And the engine is balanced by BMW's system that is unique in standard
motorcycle design: an additional swivel con-rod
balances the first and second level mass forces and
ensures that the two-cylinder functions with the
minimum of vibrations.
The low dry weight of 178 kg makes a major
contribution to the dynamic riding properties.
When filled with fuel and ready to ride, the F 800
GS weighs in at just 207 kg (456 lbs.).
The F 800 GS is claimed to offer an excellent
level of seat comfort for both rider and
passenger, along with a high standard of safety
features. If required, it can be fitted ex factory
with two-channel ABS that can be switched off. In
addition, the extensive range of BMW accessories
meets the further individual wishes of BMW's

F 800 GS Design
The parallel twin familiar from the F 800 S/ST
models forms the basis for the GS drive. For the new
usage, however, some aspects of the engine have been
modified. In order to allow long spring travel with
a wheel spacing that remains moderate, plus an ideal
distribution of weight, the cylinders are
now only angled forward by 8.3 degrees instead of
the 30 degrees with the F 800 S/ST.
has been made possible by a new design for
the lower engine housing section made from die-cast
aluminum. It contains application points for the
engine protection plate and provides the ideal
working conditions for the semi-dry sump
lubrication. In addition, the cylinder head has been
reinforced in the area of the frame connection at
on the right.
The GS engine has a modified clutch
cover which creates more space in the footrest area
and more room for a new oil dipstick and a changed
clutch release shaft. Finally, the water pump
housing and cooling hose connections have been
adapted to the new position of the engine.
The side-effect of these modifications is that the
engine is a kilogram lighter than the unit used in
the S/ST model series.
Like the famous F 800 engine, the transverse
parallel twin works with an
even firing order (360° ignition offset) without
crank offset on the crankshaft. Because there is
one firing cycle for each crankshaft rotation, the
sound is deliberately like that of boxer engines
which work with an identical firing offset!
Most importantly, however, the even firing
sequence creates the best conditions for a balance
load change with high torque yield.
Unique Engine Balancer
The mass forces are offset by a balancing mechanism
that is unique in series engine design. Instead of
having conventional counterweight shafts, the
oscillating mass forces are balanced by a joint
system on the center of the crankshaft with
deliberately positioned counterweight masses: an
eccentric on the crankshaft offset against the crank
pins by 180° carries what is known as a balancing
This connecting rod is hinged to an
approximately horizontal balancing rocker. The
kinematics are designed in such a way that the
balancing connecting rod moves contrary to the two
engine connecting rods. Because it is guided
through the relatively long rocker, an almost linear
swivel movement of the connecting rod head is
achieved -- that is, the small connecting
rod eye describes a slightly curving path.
distribution at the connecting road head and rocker
is chosen in such a way that the mass forces
resulting from the swinging movement combat, in
every crankshaft position, the oscillating mass
forces from the crank drive (piston and con-rod
proportion). This means that first and second order
mass forces are almost completely eliminated,
resulting in low-vibration engine running.
The oil circulation system of the F 800 GS
engine also includes a number of
sophisticated details. To prevent punch losses, a semi-dry sump
lubrication system has been designed which works
without any separate engine oil tank.
coming from the main bearings collects in a tray
which also holds the balancing system and which is
sealed off from the actual oil tray. Oil in this
area is constantly vacuumed up by an oil pump and
transported to the transmission housing, before
running from there, under no pressure,
via openings in the crank housing into the oil tray. The oil pressure pump
supplies the lubricating oil system from this
Cam Shafts and Timing
The cylinders in the GS engine are fitted with a
high-tech cylinder head.
As in the new engines in the K model range, here
also, two upper camshafts driven by a toothed chain
rotate and control four valves per cylinder via cam
The F 800 GS, unlike the S/ST models,
uses slightly modified camshafts which help the
engine develop its power in a way that is ideal for enduros: with excellent torque, even and easily
controllable. The valve drive via cam followers is
low-wear, only produces minimal friction losses and
is particularly rev-proof. The valve play therefore
only needs to be checked after 20,000 km at the

Other features that are typical of BMW include the
fuel mixture preparation,
which is via a manifold injection with BMS-KP engine
control and two 46 mm throttle valves. The injection
quantity is determined by the specially tuned engine
control, not only via the injection period but also
via the pressure that the fuel pump provides,
depending on the power requirement.
The fuel system
operates without return and only carries the
quantity that the engine actually needs. Because of
this economical, patented regulation system,
the fuel pressure can be modified within a wide
range so that the mixture is always ideal.
measure the fuel quantity supplied, not only the
well-known parameters such as load, engine speed and
temperature are used, but
also the residual oxygen content in the exhaust gas. The corresponding information is provided by a
lambda probe positioned at the point where the
manifolds join. This is followed immediately by the
three-way catalytic converter, provided as standard,
which quickly warms up after the cold start and can
thus start its conversion work quickly.
The air necessary to form the mixture reaches the
new suction silencers via suction snorkels
positioned in the cool air stream. The positioning
well above the engine, which is good for both
on-road and off-road riding, and the
large volume, which supports torque were made
possible by the positioning of the tank under the
seat. The suction snorkels of the F 800 GS are
visible as a design element.
The completely new, weight-optimized exhaust gas
system is made entirely from high-grade steel and
weighs in at just 8.5 kg. The single-wall manifold
system is connected with the silencer via a plug
connection with tension spring.
The attachment of a
slip-on silencer is therefore easy and less costly,
especially since the catalytic converter is
integrated into the manifold. The end silencer
provided as standard is constructed as a two-chamber
silencer in a combined absorption/reflection design,
offers a gas flow volume of 8 liters and is mounted
on the left side of the motorcycle, half way up.
F 800 GS is fitted with a secondary air system
which, in combination with
the regulated catalytic converter, reduces the
emission of pollutants to EU3 requirements.
High-Revving Engine With Great
The modern fuel injection system isn't the only
ensures a prompt response from the F 800 GS twin;
its low centrifugal mass also contributes to its
agile power development. Even at the bottom of its
rev range, the four-valver, which, with a
bore-stroke ratio of 82 to 75.6 mm is not
particularly short-stroked, soon speeds up and
releases a good 90% of the maximum torque
in the broad range between 4,000 and 7500 RPM.
Between 5,000 and 8,000 RPM, the engine develops
its power dynamically, accompanied by
a unique "Boxer" sound. The nominal performance data of the
798 cc twin of 85 HP at 7,500 RPM and 61 lb-ft of
torque at 5,750 RPM therefore gives an incomplete picture of
the potential that is available in practice.
In combination with the low total weight and closely
stepped six-speed trans-mission, the F 800 GS
accelerates from 0–100 km/h in about 4 seconds, and
the top speed is over 200 km/h.
But it is not only the acceleration of the new GS
model that is impressive; its traction is also
remarkable. The BMW development engineers have
focused quite deliberately on the smooth, confident
development of power in the mid engine speed range
rather than on absolute peak performance.
riders will be bowled over by the engine’s
acceleration, while touring riders should enjoy the twin’s
strong traction with minimal shifting.
The parallel twin, which has been optimized for
Enduro operation, not only manages to walk the
tightrope between powerful torque and dynamic
acceleration, it also proves that good performance
does not necessarily involve high fuel consumption.
Ridden over country roads, a consumption
of well below 5 liters of premium grade fuel per 100
km is possible.
If required, the F 800 GS can also be fitted for use
with normal octane fuel,
which, however, reduces the peak performance by 2 HP
and increases fuel consumption slightly. This
modification is carried out by calling up a
characteristic map in the control software, and can
be cancelled again at any time.
The sophisticated engine concept shows additional
technical finesse in its peripherals. The water
pump, for example, is on the right of the cylinder
head and is driven by a cog wheel unit on the
camshaft. The advantageous positioning of the pump
-- directly behind the radiator with integrated
thermostat -- means that only short hose connections
are needed. The engine therefore looks particularly
compact and tidy.
An oil-water heat exchanger next
the easily accessible oil filter ensures that the
engine warms up particularly quickly after a cold
start. In addition, the heat exchanger also limits
the engine oil temperatures.
has fitted the F 800 GS with chain drive.
BMW says that "because motorcycles suitable for off-road use are
often used on roads that are unfinished, they need a
secondary drive that is not sensitive to dirt."
The F 800 GS therefore has an O-ring chain with a
division of 5/8 x 5/16.
A chain guide rail protects the
aluminum rocker from damage. Four asymmetrical
drive dampers provide shock absorption for the chain
wheel bearer which is taken exactly over the
full-floating axle via a grooved ball bearing.
While the six-speed transmission is taken from the F
800 S/ST models and only the transmission output
shaft has had to be modified to the chain
drive, the end transmission ratio has been changed. The F 800 GS thus works with a transmission ratio of
1:2.625 (16/42 Z).
Tubular Steel Frame
The tubular steel frame designed specially for the
new GS models, built
as a tubular space frame, offers a whole range of
which improve the extraordinary off-road qualities
of the GS models.
slim steering head, for example, which is integrated
with total stability
into the frame structure, allows a steering lock
stop of 42 degrees. The steering head is fixed using
a completely new layout of gusset plates which have
considerably reduced the design width without
affecting the stability of the frame.
lock is also improved by the fact that the steering
lock is positioned in front of the handlebar. Off-road, the small turning circle of the GS is
particularly advantageous when the bike has to be
ridden through trial sections at walking speed.
The tubular space frame in manganese-alloy steel
integrates the engine as
a bearing element into the framework. The frame
tubes are brought together in the area of the rocker
bearings in forged steel parts. The frame tail made
from rectangular steel pipe is taken up by the main
frame via four screw connections and carries the new
fuel tank (capacity 16 liters) which is positioned
under the seat.
The new design was not only required
because of the modified engine. In the front part of
the bench seat, not only are the main frame and
frame end very narrow, the seat itself and the
covering of the suction silencer are very
streamlined. This means that, in relation to the
seat height, a very short arc has been
achieved, which is the decisive dimension for being
able to touch the ground.
The result is that the GS
provides perfect seating both for giants of the road
and for smaller riders.
Made-to-measure telescopic forks were designed for both models.
Because of the very long spring travel of 230 mm, an
upside-down telescopic fork is the best choice for
the F 800 GS.
The overlapping of the fixed and
sliding tubes is particularly large with this
design, especially since the fixed tube diameter of 45 mm ensures
excellent bending strength. Plastic deflectors
combined with the front wheel covers provide
protection against stones.
Aluminum Double-Strut Swingarm
The rear wheel suspension of the GS is similarly
robust, with real slave qualities. It is based on an
aluminum double-strut swingarm, die-cast in a single
The F 800 GS uses a directly hinged central
spring strut with path-dependent damping and spring
travel of 215 mm.
The spring pre-tensioning can be
adjusted using a handwheel, so that the rear wheel
suspension can easily be adjusted for one- and
two-person use. The tension stroke of the suspension
can also easily be adjusted to individual
Wheels and Tires
The F 800 GS travels on aluminum spoked wheels, size
21 x 2.15 at the front and 17 x 4.25 at the rear.
The front wheel size of 21-in, which is normal in
Enduro sports, gives greater riding stability
because of the greater gyroscopic forces, which can
be an inestimable advantage on loose ground.
Road-capable Enduro tires are standard, but tires
with a marked stud profile are also approved, and
refitting is easy if the motorcycle is to be used
The tire sizes are also proof that the F 800 GS is
tailored to its preferred area of use. It travels on
tires measuring 90/90-21 at the front and 150/70-17
at the rear. While the front tire supports easy
handling and minimizes braking torque, the rear
tires takes account of the high engine power.
F 800 GS
Tires: Tubed or Tubeless?
UPDATE: From H.B.C.: "Rick, now
confirmed - the F800GS has centre-spoke wheels, with
tube tires. The F 605 GS of course has the
aluminum wheels with tubeless tires.
various forums there already seems to be lots of
discussion/complaints about why BMW went (back) to a tubed
tire on the F800GS (although when you run a 21 inch
front end that pretty much sets the solution) rather
than running what has become an accepted and highly
reliable standard on the larger GS models: a 19
front and a 17 inch rear aluminum or side-spoke
wheel that let you run a tubeless radial or a tire
with a tube if desired.
might possibly offer a tire option for
the F 800 GS when it finally hits the streets. A
21 inch wheel with a thin tire is a real compromise
for mixed street, high speed road and off-road work
that heavily favours the off-road. Testers have
already admitted that the front wheel inhibits
highway driving, much like the 21 inch wheels on
some KTM models did. I think options should,
or will be available for the F 650 GS as well by the
next model year.
Unless BMW provides an option, there is going to
be a lot of activity as F800GS owners swap out the
front, or both wheels, for other roadgear sets.
From my perspective, other than the aluminum wheels
used, and if a front tire change can be done for a
19, then this model is likely to garner the market,
which is what BMW has tacitly accepted anyway."
Braking Systems Meet On- and Off-Road
The F 800 GS braking system is
also matched to the intended purpose. Because
the F 800 GS is capable of reaching
high speeds, the front wheel has two fully floating
brake discs 300 mm in diameter with double-piston
F 800 GS ABS "Expanded Diagnosis"?
wBWvisitor "J.S." says "This is really apples

they're monitoring the sensor/sensor wheel

At the front the steel-reinforced
brake lines are laid in such a way that they do not
push through the cockpit fairing when the telescopic
fork is compressed. At the rear wheel, the GS is
slowed down by a 265 mm disc brake with
single-piston sliding caliper.
An option is BMW's latest two-channel ABS with improved rear wheel
lift-off detection. The current generation of BMW's ABS is characterized not only by its
compact design and low weight, but also by its very
short braking paths.
The pressure modulator controls
the optimum braking pressure in the regulating range
via intake valves that are adjusted on a linear
basis and is characterized by its very fast, fine

variable cross-section openings also ensure that the
rider only perceives a slight pulsing in the brake
In addition, the BMW ABS system offers
expanded diagnosis functions: the wheel speed
sensors monitor their distance from the sensor wheel
automatically and thus contribute to the
motorcycle’s outstanding safety. Riders who
routinely ride off-road can deactivate the ABS
system before off-road use.
On-Board Electrics With CAN Bus and
The electrical system in the new GS is also at the
top of the range, and works with an innovative CAN

model series, the single-wire system (SWS) has many
advantages: it reduces the amount of wiring
required, allows all control devices to be networked

In addition, there is no need for
conventional fuses, since the system automatically
switches off the component in question in the event
of a malfunction.
Since the introduction of CAN bus technology, an
electronic immobilizer has been part of the standard
equipment on BMW motorcycles. More than the
key is needed to start the engine; the
chip integrated into the BMW key must report the
right code to the ring antenna of the combined
steering and ignition lock. Only then does the
engine control allow the vehicle to be started. This

Last but not least, the
fairing discs offer moderate wind protection, thus
helping the passenger to travel in comfort. The high
windscreen with its M-shaped design has been
optimized in a wind tunnel.
The 16-liter fuel tank under the seat has proved a
great advantage on long trips, not only because long
distances can be traveled, thanks to the
motorcycle’s low fuel consumption, but also because
the tank bag can be left in place as the tank is
filled. The lockable filler nozzle is easily
accessible on the right-hand side of the motorcycle

In order to offer shorter riders optimum ergonomics
and the ability to reach the ground, BMW has fitted
the F 800 GS with a lower seat. It reduces the

Note on Vario Cases and the Vario Top Case
The well-known, variable-volume saddlebag side cases (left
19–29 liter; right case:
28–38 liter) have been modified to the new GS
models. Thanks to the care-fully conceived carrier
system, the cases can be attached and removed in
Those who want to take even more luggage
with them can also add the 25–35 liter top case,
which has plenty of room for a helmet, for example. If required, the comfort of the passenger can be
improved by attaching a back cushion to the top case. The inside pockets for the cases reliably protect
luggage from dirt and damage.
The tankbag designed for the F 800 GS is a practical traveling
companion. Because the fuel tank is positioned
underneath the seat, the tank bag does not need to be
removed in filling stations. The tank bag has a
variable capacity of 14 to 26 liters and
has a waterproof inside pocket so that no extra
covering is required when traveling in the rain.
The bag also includes a waterproof map compartment
and a place for small tools which can be accessed
via the main compartment from the inside.

guidance using a helmet installation kit is possible
in nine languages.

dyed plastic can take on a variety of protective
functions, since individual modification is possible
with the modular system. The hand protection bar

The sports silencer in titanium and carbon made by
Akrapovic fits without problems onto the original

the standard system.
Enduro Tail Bag
This special tail bag attached behind the seat
resists even the tough loads
