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 naked in the segment of medium category naked bikes designed for a high level of riding dynamics and maximum riding fun. Alongside the two naked R 1200 R and K 1300 R, this is now the third BMW naked bike 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 beneficial pleasant for the rider.

Closely based on the big BMW 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.

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.
- Intake 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 purified 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.
- Very 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.

Powerful parallel-twin for characteristic 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 naked bike 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.

With the F 800 R, BMW Motorrad has realised a design concept which deliberately highlights the connection with the large sporty 4-cylinder naked bike 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 Motorad 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 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 equipment program.
