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 tradition.
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
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
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 sporty performance.
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
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
What is more, the extensive BMW Motorrad accessory program
meets all customer demands in terms of individual fittings.

Wide range of accessories.
Powerful parallel-twin for characteristic roadster dynamic
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 riding dynamics.
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 flat 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 smoothness.
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
mass 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 intervals.
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 carburetion. 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
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
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 new circumstances.
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 converter.
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 fun.
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 fuel consumption.
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 fuel tank.
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
stability. 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 bolt connections.
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 the rear.
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 as standard.
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 precision.
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 level.
4. Electrical system and electronics.
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
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 flasher 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.
5. Body and design.
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 high-quality style.
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

passenger cover and an engine spoiler are to be found in the extensive BMW
