2005 BMW F650 CS

Poised at the intersection of performance and styling, the city-savvy 2005 F 650 CS redefines the term ”urban assault vehicle.” Combining BMW’s new 2 SPARK ignition system with an on-board computer system five times as powerful as the original, the new F 650 CS has significantly increased fuel efficiency giving you more metro miles to the gallon.

Agile and downright fun to ride, the new F 650 CS provides other added enhancements including new 3 position adjustable clutch, the now standard on-board power socket, and super-smart stuff bay.

For customization, you can choose from four startling color schemes with optional side cover and seat accent options. Other optional accessories and features include ABS, rear touring suspension, a hard-box audio system, anti-theft alarm and the sleek chrome kit.

Built to trump the tests of inner city traffic, the new 2005 F 650 CS also offers a smooth, punchy ride on one-day getaways and weeklong vacations.



Combined with the dual headlight and the grayish-blue-tinted windshield, the F 650 CS comes with an entirely new face from the front.

The low-beam headlight in ellipsoid technology provides a bright, efficiently bundled light beam, the high-beam headlight in free-form technology ensures broad illumination of the road ahead. A small parking light is housed conveniently in the middle, beneath the two headlights.

The windshield mounts, storage compartment rail and luggage rack – are now finished in a stark, opaque black.

No less than five different, easily interchangeable inserts are available for the new storage compartment. Instead of the softbag featured as standard, a frontbag is available both as an optional extra and as special equipment. The frontbag is finished in blue/gold color-matched to the motorcycle. Absolutely watertight with its lockable inner bag, the frontbag comes additionally with a separate pouch for valuables, a bag for the rider’s mobile phone, and a removable map folder. For even greater convenience, the frontbag converts easily into a backpack for the rider.

The F 650 CS comes with a 3.9 gallon fuel tank cleverly located in the frame triangle beneath the seat, in the interest of a low center of gravity and optimum handling. The tank filler manifold, in turn, is positioned conveniently on the right-hand side of the seat, which is available at two different height s: 30.7” (standard) or 29.5” (available as an option). The lower seat height options also incorporates the use of 150/60 ZR 17 rear wheel and 150/ 60 ZR 17 front wheel.

The F 650 CS comes with a single-disc brake at the front with a two-piston floating caliper. The rear brake consists of a single-disc brake with a single-piston floating caliper.

It almost goes without saying that ABS anti-lock brake technology is also available as an option on the F 650 CS, in this case specially developed for BMW’s single-cylinder model series.

The fully controlled three-way catalytic converter and the oxygen sensor are integrated in the silencer made of polished steel. This not only saves space but also reduces emissions and is therefore friendlier on the environment.

Just one look at the right-hand side of the rear wheel reveals the two outstanding innovations on the F 650 CS never to be seen before in this combination on a BMW motorcycle: the single swinging arm and toothed belt drive.

Introducing toothed belt drive, BMW is opening up a new chapter in rear-wheel-drive technology in the company’s 80-year history of motorcycles: For no less than 70 years – from 1923-1993 – all BMW motorcycles were built exclusively with the drive shaft so typical of the BMW marque.

The process of fitting and removing the rear wheel on the F 650 CS is even easier and just as clean as on BMW’s motorcycles with shaft drive: After removing the silencer, all the rider has to do is open up a central bolt to remove the wheel with ease. Both the sprocket and the drive belt remain on the swinging arm and do not have to be taken off.

The single swinging arm on the F 650 CS convincingly continues BMW’s tradition of innovative wheel guidance systems. This heritage dates back to 1980, when BMW introduced the rear-wheel swinging arm for the first time on the R 80 G/S (the BMW Monolever). The efficient and beautiful single swinging arm on the F 650 CS is made of aluminum.

This helps to significantly enhance the stability of the suspension and running gear. Also made of aluminum, the wheel mount rests eccentrically on the swinging arm bearing point, making it much easier to fit and remove the rear wheel and ensuring simple, precise adjustment of belt tension.

BMW’s 2 spark ignition system and improved catalytic converter improve fuel efficiency and reduce emissions and keep the new F 650 CS easily compliant with current exhaust emission standards.
