VEHICLE REVIEW

2009 BMW F800R

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 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 sporty performance. Important contributions to the outstanding dynamics of the new F 800 Rare 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.

OVERVIEW SPECIFICATIONS

ENGINE

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 riding dynamics.

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 hinge don 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.

FUEL SYSTEM

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 800 R.

PERFORMANCE

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 fs 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 82.0to 75.6 millimetres quickly gains engine speed and delivers 90 percent 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.

ELECTRICAL SYSTEM

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.

TRANSMISSION

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

EXHAUST SYSTEM

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 loopcatalytic converter.

BODY FRAME

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.
