2009 BMW F 800 R
Overall concept and vehicle properties.
BMW most recently struck out on a new path in the
segment of medium category motorcycles with the F
800 series launched in 2006. In addition to the sporty
F 800 S, the first model variation to be presented,
and the F 800 ST with its touring capabilities, the
fourth BMW Motorrad engine series was supplemented
in 2007 with the F 800 GS and the F 650 GS –
two dynamic enduro models in the very best BMW GS
With the new F 800 R, BMW now takes the logical
step of expanding the F 800 model series further by
presenting at the EICMA 2008 – the Milan motorcycle
show - a sporty roadster in the segment of medium
category naked bikes designed for a high level of
riding dynamics and maximum riding fun. Alongside
the two roadsters R 1200 R and K 1300 R, this is now
the third BMW roadster to see its world premiere in
the BMW Urban world of experience: the new F 800 R,
the dynamic BMW naked bike for the medium category.
The engine of the F 800 R is the parallel twin with
4-valve technology and a capacity of 798 cc, already
familiar from the F 800 S.
While the highly distinctive in-line 2-cylinder
engine of the previous models was especially impressive
due its pulling power, spontaneous response and low
level of fuel consumption, the new model now reflects
a further optimisation of engine and throttle response
thanks to a new throttle valve kinematic system.
The rated output of the engine is 64 kW/87 bhp at
approx. 8,000 rpm and produces a torque of 86 Nm at
approx. 6,000 rpm. The mass compensation of the parallel
twin is implemented by a system which is still unique
in serial production motorcycle construction in which
an additional swivel rod compensates the first-order
and second-order mass forces, ensuring that the 2-cylinder
engine runs with an unusually low level of vibration
which is especially pleasant for the rider.
Closely based on the big BMW roadster K 1300 R in
its design, the distinctively sporty F 800 R with
its orientation towards a high level of riding dynamics
delivers just what its dynamic exterior promises.
From standing, the F 800 R possesses considerable
sprinting power. What is more, shorter gear ratios
in fourth to sixth gear ensure improved continuity;
in conjunction with the excellent pulling power of
the two-cylinder this makes for a highly agile and
Important contributions to the outstanding dynamics
of the new F 800 R are also made by the low dry weight
of approx. 182 kg or approx. 204 kg fully fuelled
and the chassis with double-sided rear-wheel swing-arm
which is especially adapted to the requirements of
a sporty naked bike. In accordance with the style
and purpose of a sporty naked bike, the new F 800
R also has a secondary drive with O-ring chain.
In line with the demands of a dynamic roadster,
the chassis is designed for excellent handling, agility
and steering precision, and therefore maximum riding
fun on winding country roads, though without compromises
in terms of directional stability at high speeds,
for example when riding on the motorway.
The streetbike freestyle world champion Christian
Pfeiffer provides a foretaste of just how playfully
the rider can handle the F 800 R. For over two years
now he has ridden a version of the F 800 S exclusively
tailored to his needs at international competitions
and shows: the similarity of this bike to the current
F 800 R is by no means coincidental. In future, the
motorcycle acrobat will be able to demonstrate his
skills on a machine based on the new F 800 R.
But the new F 800 R boasts more than just sporting
talent: in the very best tradition of BMW it also
possesses classic virtues such as outstanding seating
comfort for rider and pillion passenger as well as
an exemplary level of safety. For example, the F 800
R is optionally fitted with an ABS whose newly developed
pressure sensor provides an even finer regulation
of the system and therefore even greater safety –
especially in connection with sporty riding.
What is more, the extensive BMW Motorrad accessory
program meets all customer demands in terms of individual

Powerful parallel-twin for characteristic
roadster dynamic performance.
The new F 800 R is fitted with the 2-cylinder in-line
engine with cylinders tilted forward by 30 degrees:
the engine is largely familiar from the F 800 S.
With its full torque curve and spontaneous response
at all engine speeds, it offers an excellent basis
for use in a roadster designed for a high level of
In the segment of medium category naked bikes, the
2-cylinder offers a number of technical highlights.
As reflected in the engine designation parallel twin,
the crankshaft has a crank offset angle of zero degrees.
This means that the engine, installed transversely
to the direction of travel, operates with an even
firing sequence in which a combustion cycle is initiated
at every rotation of the crankshaft. This results
in an intentional similarity in sound to the fl at
twin “boxer” engines, which also operate
at a firing angle of 360 degrees. In particular, the
even firing sequence supports a balanced gas exchange
cycle with high torque efficiency and a harmonious
curve, thus fulfilling the basic requirements for
a dynamic engine in a sporty naked bike.
Unique mass compensation for maximum running
The first and second-order mass forces which are
unavoidable in 2-cylinder engines are neutralised
by a unique compensation mechanism which is familiar
from the existing models of the F 800 series. Instead
of using the conventional method of so-called compensation
or counterbalance shafts, compensation of oscillating
mass forces is effected by means of a system of pivots
which is linked centrally to the crankshaft with a
specifically defined arrangement of counterbalance
masses: a tappet on the crankshaft offset from the
crank pins by 180 degrees carries a so-called compensation
rod. This rod is hinged on a balance arm which is
virtually horizontal. The kinematics of the system
is designed so that the compensation rod moves up
and down in the opposite direction to the two engine
rods. Due to the fact that it runs via a relatively
long arm, the rod head moves virtually in a straight
line. The distribution of masses at the rod head and
arm has been selected so that the mass forces resulting
from the swivel movement counterbalance the oscillating
forces of the crank drive (piston and rod elements)
in every position. This almost entirely eliminates
the first and second-order mass forces and makes for
a very low level of vibration when the engine is running.
Another great advantage of this elegant construction
is its low noise level, since the typical engine noises
of cogs and chains do not apply here.
Oil circulation with semi-dry sump lubrication.
The oil circulation also has a number of special
technical features which go beyond what is standard
in this category of motorcycle. In order to minimise
splash losses, the F 800 engine series has a semi-dry
sump lubrication system. Any oil escaping from the
main bearings of the crank drive runs into the sealed
off shaft of the compensation system. An oil pump
extracts the lubricant from here and distributes it
to the oil jets in the gearbox. Oil escaping from
the gearbox via gaps in the crankcase is collected
together with the oil escaping from the cylinder head
via the chain shaft in the remaining space of the
crankshaft casing around the rod shaft. This space
is thus used as an integrated oil tank. A second pump
feeds all bearings from this reservoir.
High-tech cylinder head as in the current
K 1300 models.
Two overhead camshafts rotate in the engine of the
F 800 R, driven by a chain drive and activating four
valves per cylinder via cam followers. As a light,
low friction and high-rev-suitable cam follower construction,
the entire valve drive is extremely low-wear in spite
of the large valve stroke, making for generous maintenance
Injection with new throttle valve kinematics.
Other characteristic BMW features are demonstrated
by the fuel-mixture preparation which is carried out
by an intake manifold fuel injection system with BMS-KP
engine management and two 46-millimetre throttle valves.
Here the engine management system controls the injection
quantity not by means of the duration of injection
but via the pressure provided by the fuel pump depending
on the required level of power. The fuel system works
without a return system and only transports the quantity
which the engine actually needs. This power-saving
quantity control means that fuel pressure can be adjusted
across a wide range to achieve optimum carburation.
This unique principle is patented. In order to measure
the quantity of fuel injected, not only are the familiar
parameters such as load, engine speed and temperature
used but also the residual oxygen content of the exhaust
emissions. The relevant information is provided by
an oxygen sensor positioned behind the junction of
the manifold pipes: this is indispensable for effective
conversion of exhaust emissions by the separate 3-way
catalytic converter which is installed as standard
in the F 800 R.
For the first time, a new throttle valve kinematic
system is used in the F 800 R which ensures an even
more sensitive throttle response and improved engine
response. It was especially important to developers
to make sure that the accelerator maintained a gentle,
finely tuned response, especially in the lower speed
range. Great importance was also attached to an accommodating
load-change response while retaining a spontaneous
and agile engine response.
The air required for carburetion reaches the intake
silence by means of an intake snorkel positioned ideally
in the cool air stream. As in all models of the F
800 series, this favourable positioning above the
engine and the
large volume for enhanced torque is possible due to
the shift of the fuel tank under the seat.
New exhaust system in dynamic design with
separate catalytic converter.
A new exhaust system with a separate catalytic converter
has been developed for the F 800 R. This is no longer
integrated in the silencer as in the F 800 S.
As a result the silencer of the F 800 R, made entirely
of high-quality steel and with a matt surface, is
considerably shorter and contributes to the sporty,
dynamic look of the new BMW medium category roadster.
The engine management system has been adapted to the
A secondary air system enriches the exhaust gas
with fresh air so that pollutant emissions are reduced
to a minimum after treatment in the closed loop catalytic
High-revving and high-torque.
As with the F 800 S, not only the state-of-the-art
fuel injection system of the new F 800 R contributes
to the bike’s highly agile power delivery but
also the low centrifugal mass. Even in the lower engine
speed range, the
not especially short-stroke 4-valve engine with its
bore-stroke ratio of 82.0 to 75.6 millimetres quickly
gains engine speed and delivers 90 per cent of its
maximum torque at 5,000 rpm. Between 5,000 and 8,000
rpm the engine demonstrates impressive power delivery
to the accompaniment of a unique sound. The rated
performance figures of the 798 cc twin – 64
kW/87 bhp at approx. 8,000 rpm and 86 Nm at approx.
6,000 rpm – provide a high level of performance
potential for the F 800 R, especially when riding
on country roads.
Optimised gear spacing for increased riding
While the gear ratios for gears one to three are
identical to those of the F 800 S, gears four to six
have been adapted to more common use on winding country
roads with a shorter ratio so as to increase riding
fun, agility and riding dynamics.
In this way, the parallel twin of the F 800 R combines
impressive pulling power with dynamic spring capacity.
At the same it demonstrates that sporty performance
by no means comes at the price of a high level of
When riding the bike on country roads, a fuel consumption
rate of well below 5 litres of premium fuel to 100
kilometres is feasible, allowing for an impressive
range of 300 kilometres or more with the 16-litre
BMW Motorrad also offers an ex-works power-limited
version at no extra charge with 25 kW/34 bhp at approx.
7,000 rpm and 55 Nm at approx. 3,500 rpm, for motorcycle
novices who hold a restricted licence, for example.
The power reduction is implemented by means of an
altered throttle valve system which limits the opening
angle of the throttle valves.
Sporty secondary drive with O-ring chain.
In order to do justice to its sporty, dynamic orientation,
the new F 800 R has been fitted with an O-ring chain
for its secondary drive. This has proven its low maintenance
and reliability and is in keeping with the especially
dynamic appearance of a naked bike in this segment.
Engine and chassis in perfect harmony.
In the F 800 R as in all models of the F 800 series,
the compact design of the engine and chassis provides
the ideal basis for exemplary riding properties which
set benchmarks in terms of agility and directional
The extremely torsionally stiff aluminium frame, familiar
from the F 800 S and made of welded extruded sections
and die-cast mould parts, ensures a virtually straight-line
connection between the steering head and swing arm
pivot point. In order to optimise weight and space,
the engine is integrated in the chassis as a load-bearing
element and its casing with reinforcement in the rear
section also performs the function of a bearing for
the new double-sided swing-arm in light alloy cast
with a total of four needle roller bearings. The engine
block is bolted to the frame immediately above the
swing-arm bearing. The frame rear section in steel
tubing is largely the same as that of the F 800 S
and is connected to the main frame by means of four
New double-sided swing-arm in sporty design.
The new F 800 R is fitted with a double-sided swing-arm.
Unlike single-sided swing-arms it is a highly filigree
construction in light alloy cast, giving an especially
agile and sporty look and highlighting the very dynamic
overall character of the new F 800 R, especially at
For the front wheel suspension in the F 800 R, a
telescopic fork is used with 43 millimetres of stanchion
diameter and generous covering of the immersion tube
and stanchion. The solid suspension system benefits
not only directional stability but also steering response.
Agile banking changes in the new F 800 R are carried
out with a high degree of steering precision and a
very direct sense of the front wheel – a guarantee
of maximum riding fun on winding country roads. The
spring-damper settings are adjusted for increased
riding dynamics and the 125 millimetres of spring
clearance ensure both outstanding comfort as well
as solid road-holding. A steering damper is fitted
A new upper fork bridge forged out of light alloy,
with steering stem clamps which are also forged, supports
broad, butted light alloy handlebars. The fork stabilizer
is also new, ensuring additional torsional rigidity
and further increasing ride stability and steering
Balanced weight distribution and a favourable total
weight equally contribute to the excellent riding
dynamics of the F 800 R. Road-ready and fully fuelled
it weighs only approx. 204 kg – its unladen
weight is approx. 182 kg.
The rear strut has adjustable rebound stage damping
and an easily accessible handwheel for adjusting the
spring pre-tension. Its spring-strut settings have
been adjusted for use in the new F 800 R. A socket
wrench enlarges the contact surface of the handwheel
so the rider can quickly and easily adapt the spring
pre-tension to different load conditions. Directly
pivoted to the double-sided swing arm, the strut also
provides 125 millimetres of travel.
Sporty wheel design.
The F 800 R features the wheel design “Speed”
of the F 800 S. In these light alloy die-cast wheels,
the valve is mounted on the side, which makes checking
the tyre pressure very convenient. The front wheel
size is 3.5 x 17" with a 120/70 ZR 17 tyre, while
the rear wheel is 5.5 x 17", allowing a size
180/55 ZR 17 tyre to be mounted.
Uncompromising Brembo brake system.
With 320-millimetre steel brake discs and Brembo
4-piston fixed brake calipers for the front wheel,
the F 800 R is fitted with a brake system which one
would generally expect of a large-volume naked bike.
The brake calipers work with sintered metal pads and
the main brake cylinder has an adjustable lever as
well as a separate storage container. At the rear
there is a single-piston floating caliper on a 265
millimetre steel disc.
High-quality steel-reinforced brake lines, been re-laid
to meet the special requirements of the F 800 R, ensure
a stable pressure point which can be clearly felt.
Optimised ABS with new pressure sensor.
The new F 800 R can be optionally fitted with ABS.
This BMW Motorrad ABS is distinguished not only by
its compact construction and low weight but has also
been further optimised for use in the F 800 R with
a new pressure sensor.
In keeping with the sporty function of the F 800
R, the re-adjusted pressure sensor system allows even
more finely tuned regulation of the ABS, for example
when going over bumps.
What is more, BMW Motorrad ABS provides integrated
diagnosis functions. For example, wheel rotation sensors
automatically monitor their distance from the sensor
wheel, thus enhancing the bike’s excellent safety
Electrical system with CAN bus technology.
The electrical system of the new F 800 R works with
the progressive CAN bus system familiar from the existing
models of the F 800 series. The Single Wire System
(SWS) offers numerous advantages: it reduces the amount
of wiring, allows all control units to be networked
with each other and thus simplifies the provision
of extensive diagnoses. What is more, safety fuses
are no longer required because the system automatically
deactivates the affected component in case of malfunction.
Since the introduction of CAN bus technology, an
electronic vehicle immobilisation function has been
a standard feature of most BMW motorcycles, and this
also applies to the new F 800 R. The electrical plug
connections are waterproof and thus insusceptible
to faults. A powerful battery with a capacity of 14
Ah and a powerful alternator with an output of 400
watts provide the power supply.
Instrument panel in new design.
The cockpit with its analogue instruments informs
the rider at a glance. For the F 800 R the dials have
been redrawn and adapted to the dynamic appearance
of the F 800 R in terms of design. As a special equipment
option, BMW offers an on-board computer which also
provides a stopwatch function among other features.
The asymmetrical dual headlamps with the technology
familiar from the F 800 GS give the new F 800 R a
sporty, aggressive face and intentionally echo the
design of the big roadster model K 1300 R. Two H7
headlamps ensure that the rider can see and be seen.
New electrical switch units.
As in the new K 1300 models, the F 800 R features
switches and controls of an entirely new generation.
The new switch units use MID technology (Moulded Interconnect
Devices; lasered conductors instead of individual
wiring) and are thus much smaller and more compact
while also offering a wider range of functions, clear
design and optimum reachability.
The functions of the left and right direction indicators,
previously separate, are now combined in a single
function on the left-hand side of the handlebars.
Activation of the hazard warning lights is now taken
care of via a separate switch integrated at the top
of the left-hand handlebar panel. The functions for
low beam, high beam and headlamp fl asher have been
combined in a single switch which can be conveniently
operated using the left index finger.
The activation switch for the optional grip heating
has been moved upwards for easier operability and
the selected heating level can be seen in the instrument
panel display. The functions for starter and kill
switch have been practically combined in a single
rocker switch. This prevents the starter from being
activated when the ignition is interrupted if the
kill switch is activated by mistake, potentially resulting
in battery discharge.
The new technical design allows twice as many functions
to be provided with the same number of switches as
before. This is an important factor in the incorporation
of additional features in the future.
Sporty, dynamic roadster design.
With the F 800 R, BMW Motorrad has realised a design
concept which deliberately highlights the connection
with the large sporty 4-cylinder roadster K 1300 R.
Due to the light effect of the rear section and
the compact combination of headlamps and instruments,
the F 800 R appears short and compact, further emphasising
the sporty look of this dynamic naked bike.
BMW Motorrad has also paid special attention to
quality details in the immediate field of vision of
the rider. For example, not only have the faces of
the instrument panel been redrawn but also the upper
fork bridge with steering stem clamps, milled covering
caps and butted handlebars are finished in especially
As compared to the F 800 S, the seat height has
been slightly lowered: this will especially benefit
re-starters, infrequent motorcyclists and beginners
who will find the bike easier to handle as a result.
An additional option for the reduction of seat height
is a lower seat from the BMW Motorrad equipment program.
Additional design parts for further individualisation
of the F 800 R for example the Sport windshield, radiator
trim panels, a pillion passenger cover and an engine
spoiler are to be found in the extensive BMW Motorrad
Special equipment features and special accessories.
BMW fulfils individualisation wishes not only with
special equipment features fitted at the Berlin plant
but also by means of retrofitted accessories which
can be fitted by a local dealer or by customers themselves.
The special equipment features and special accessories
have been specially adapted to the new F 800 R so
that the buyer acquires high-quality, perfectly fitting
products which are in keeping with the character of
the machine itself.

BMW Motorrad offers the F 800 R in three attractive
paint finishes. The two-colour finish Alpine White
non-metallic with Black silk gloss reflects the spirit
of the times. Fire Orange non-metallic has a provocative,
sport effect while White Aluminium metallic matt comes
over as technical and modern.
The frame, swing-arm and engine of the F 800 R are
finished in black in all three colour versions. Together
with the light alloy wheels, also finished in black,
this makes for a particularly dynamic look which reflects
the sporty ambitions of the F 800 R. The orange-coloured
spring adds an interesting touch of colour.
The interplay between the coloured and black surfaces
highlights the newly designed body features and the
