2009 BMW F800R
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 fi rst 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 refl ects 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 fi rst-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
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 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 fi ner 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 fittings.


An overview of the main features of the new F 800 R:

- Compact, sporty naked bike with high level of riding dynamics and agility
for maximum riding fun.
- Liquid-cooled parallel twin with 798 cc, 4-valve technology, dohc valve
drive via cam followers and a unique mass compensation mechanism.
- Top output 64 kW/87 bhp at approx. 8,000 rpm, maximum torque 86 Nm
at approx. 6,000 rpm.
- Enormous pulling power for maximum riding fun on country roads.
- I ntake manifold fuel injection with electronic engine management BMS-KP,
oxygen sensor, closed-loop 3-way catalytic converter and secondary
air system for low fuel consumption and purifi ed exhaust emissions.
- New throttle valve kinematics for even more sensitive throttle response and
improved engine response, especially in the lower speed range.
- Six-speed transmission with shorter ratio of the three upper gears for
increased riding fun and performance.
- Secondary drive via O-ring chain.
- Torsionally stiff aluminium frame with new double-sided swing-arm.
- Generously sized telescopic fork with 43 millimetres stanchion diameter.
- V ery agile handling with very high degree of steering precision.
- Dry weight/road-ready weight: approx. 182/204 kg.
- Fuel tank positioned under seat for optimum centre of gravity.
- High-performance Brembo brake system with optimised ABS and newly
adjusted pressure sensor system.
- Wide range of accessories.
