BMW goes fully naked with 2009 F800R

 P0048368

BMW’s F800S and ST have been around for a couple of years now, and the combination of the 87 horsepower, midsize parallel twin and its compact, flickable chassis have won many fans worldwide. Britain’s BIKE magazine even referred to it as “the new VFR” - high praise indeed. And since super-stunter Chris Pfeiffer rode a stripped F800 to the 2007 and 2008 Streetbike Freestyle World Championships, many of us have been wondering how long it would take for BMW to get a production naked happening.

That question was answered today at EICMA in Milan; 2009 will see the debut of the F800R naked, based on the F800S but with the fairings removed, F800GS-style headlights up front, and the back end’s single-sided swingarm and belt drive replaced with a double-sided swinger and chain.

The front air scoops deliberately position the F800R as the K1300R’s naughty little brother, and if handling remains similar to the F800S, it’s sure to be a great fun bike to ride - but the looks are far from inspirational, particularly next to the similarly angular Street Triple and Aprilia Shiver. In fact it’s fair to say you’ve got to pick your angles very carefully to take a photo in which the F800R doesn’t look pretty pedestrian. Still, you don’t have to look at it when you’re wheelying madly down a backstreet or throwing it into a mountain hairpin!

Full press release follows after a boatload of photos.

 The new BMW F 800 R
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 adventure 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 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.

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 naked bike, 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 f 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 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.
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.
