2004 BMW F650CS

BMW F650

The F650 CS is a fresh concept in motorcycling, designed to appeal to a new type of customer. For the first time in BMW's history, low maintenance belt-drive transmission is used that is longer lasting and easier to service. A storage facility in the central fairing has been conceived for versatility and convenience called a Stuffbay. The F650 CS has a RRP of £5,395 on-the-road.

Designed for the city and the open road

At 780 mm (30.7 inches) the seat height is already low, but an even lower 750 mm (29.5 inches) is available as an option. This makes the F650 CS perfect for smaller riders. Because of superior handling and a quick-revving power unit, the F650 CS offers true sporting capability on country roads and tractability in city traffic. In fact, the F650 CS is excellent for all kinds of road riding.

Engine simplicity and catalytic converter

The single-cylinder engine and five-speed gearbox are the same proven units used in the popular F650 GS. Maximum output of 37 kW (50 bhp) occurs at 6,800 rpm (6,500 rpm on the F650 GS) while maximum torque has increased from 60 Nm to 62 Nm (46 lb ft) at 5,500 rpm (5,000 rpm on the F650 GS). Torque of more than 50 Nm (37 lb ft) is available between 3,500 and 7,000 rpm. Like all BMW motorcycles (with the exception of the R850 R Classic) the F650 CS comes with Digital Motor Electronics and a fully controlled catalytic converter.

Engine oil reservoir in the frame

BMW designers and engineers developed the principal (introduced on the F650) of using the frame of the motorcycle as an engine oil reservoir. Accordingly, the two upper arms of the bridge-type frame house 2.5 litres of engine oil. Relocating the fuel tank under the seat allowed the free space in front of the rider to be redesigned as a storage compartment. Exhaust system

The CSs three-way catalytic converter and oxygen sensor are integrated into a high quality, polished steel silencer. A pre-silencer is not needed and the designers have continued the lines of the manifold back to the final silencer. The two-piece, exhaust pipe covers are matt-blasted.

The single swinging arm with toothed drive-belt

Unique in its market sector, the single swinging arm on the F650 CS is made of aluminium. This provides a high level of torsional stiffness to enhance ride quality. The toothed drive-belt is clean and quiet, requires no lubrication, and on average lasts twice as long as a conventional chain.

Like its GS, the F650 CS features a bridge-frame backbone made of rectangular steel that has a larger than usual cross-section to ensure maximum stiffness. The CS uses telescopic forks with shorter spring travel than the off-road GS model (125 mm). These are specially set for road use.

Cast aluminium wheels

Silver-painted, 17-inch three-spoke cast aluminium wheels feature a curved design from hub to rim. This is the result of combining the brake and toothed belt sprocket on the right-hand side of the wheel.

The F650 CS employs a 300mm single-disc front brake with a two-piston floating caliper and sintered-metal brake pads. A 240mm single-disc is fitted to the rear wheel and features a single-piston, floating caliper. ABS brakes are a £345 optional extra. BMW is the only motorcycle manufacturer to offer ABS across its entire range.

A wide range of colours

The F650 CS is available in four colour schemes: titanium silver metallic, gold orange metallic, azure blue metallic and graphite metallic The seat colours are dark blue or sepia, and the exchangeable side covers on the central fairing can be either white aluminium or golden orange.

Ellipsoidal dual headlights

With a tinted, clear-view screen, translucent screen support and low dual headlights, the F650 CS has an entirely individual face. Featuring ellipsoid technology, the low-beam headlights emit a bright light beam. On high beam, free-form technology guarantees broad illumination of the road ahead. A small parking light is fitted in the centre, beneath the two headlights.

The instrument cluster includes a speedo and rev counter, and the design is reminiscent of a modern wristwatch. Finished in silver, the handlebars measure 745 mm (29.3 inches) while mirrors and controls are identical to the F650 GS. The fuel tank capacity is 15 litres (3.3 gals) and is situated beneath the dual seat. The low centre of gravity helps optimise handling. The fuel tank filler pipe is located on the right side of the seat. The translucent luggage rack carries a maximum load of 5 kg and is supported by two, stable aluminium grab handles.

Central fairing with innovative storage concept

Visually, the most striking feature of the F650 CS is the StuffBay area that replaces the tank. With engine oil contained in the frame, the free space has been used to create an innovative storage compartment – just above the airbox. Featuring a translucent fastening rail on each side, the compartment can take anything from a spare helmet, to rainsuit or tank bag.

BMW's designers have developed a range of accessories for the storage compartment. These include: a 12 litre capacity Frontbag that converts into a backpack made of water-repellent fabric (£53); a 10 litre plastic hardcase as a lockable storage area (£72); and a helmet net (£90) consisting of three flexible plastic arms, metal inserts and locking mechanism. An audio system (£290) has also been designed and is based on the dimensions of the hard case. It features connections for a portable CD (MP3 or MiniDisc) player, weatherproof active speakers and stereo amplifier, with manual and speed-related volume control.

Softbags for luggage rack and passenger seat

The soft luggage system includes 27 and 35 litres capacity, watertight nylon bags for the luggage rack and passenger seat respectively. The former can be adapted for use as a backpack and even combined with the rear seat bag for additional capacity.

Special equipment and optional extras

Apart from the items already listed, other special equipment includes heated grips, a carbon fibre engine spoiler, chrome trim package, on-board computer, power socket, anti-theft system, a special stand for servicing operations, hazard warning flashers and a cover.

CS rider equipment and clothing

BMW has developed a collection of rider wear to complement the introduction of the F650 CS called the Street range. It includes men's and women's motorcycle suits, boots, gloves and casual wear.
