When BMW launched the original F650GS the simplicity of the machine appealed to everyone - simplicity in design, maintenance, and riding. But simplicity cannot hide functionality. The F650GS is not just an easy motorcycle for the inexperienced to ride; it is as comfortable on tarmac as it is on dirt and is used on BMW?s award-winning Off-Road Skills courses.
By adding fuel injection and digital engine management, the single-cylinder four-stroke four-valve water-cooled engine puts out a vigorous 50bhp. Peak torque is an impressive 60Nm at 5000 rpm. Aided by the engine's new cush-drive damper, the smoothness and response of the F650GS puts an end to the myth of single-cylinder engines being basic and agricultural.
Made by Rotax, the GS engine is refined, responsive and controllable under all riding conditions. Of course, a standard closed loop, three-way catalytic converter ensures that the F650GS is one of the most environment-friendly motorcycles on (or off) the road.
Snatch-free progress, even at the lowest possible revs, is a tribute to the reliable five-speed gearbox, chain-drive transmission and light-feel clutch. The 17.3 litre (3.8 gal) fuel tank has been relocated under the rider's seat and significantly lowers the F650GS's centre of gravity. Combining this with a generous lock and tight turning circle improves balance, enhances manoeuvrability and makes the GS one of the easiest and most stress-free motorcycles for town and city riding.
By taking advantage of BMW's ergonomic options, the 78cm seat height can be adjusted to provide a more personalised riding position. Lowering the seat by 30mm is a no-cost factory option. Alternatively, it is possible to have the seat raised by 40mm - an optional extra - to provide a more practical seating position for taller riders. No other motorcycle in its class offers the same degree of adaptability as the F650 GS.
To cope with the specific stresses and rigours of off-road riding, BMW has developed a bridge-tube frame made of rectangular steel tubes with an additional crossbar in front of the cylinder head. By bolting the lower subframe to the mainframe, the engine is surrounded by steel for maximum protection.
Because the F650GS is a multi-purpose machine, the suspension set-up has been strengthened and the Showa forks incorporate an extra stabiliser that improves smoothness on rough surfaces, especially when BMW's optional ABS is used.
Damping force is provided by a two-arm, box-type, swinging arm that is made of steel. Further progressive damping is achieved by connecting the central spring strut, using a lever system, to the swinging arm. The spring strut can be adjusted infinitely for preload and outward stroke damping by using an accessible adjusting wheel.
The F650GS is equipped with 19-inch and 17-inch spoked wheels at the front and rear. Additional features include a 300mm (11.8in) single-disc front brake with twin-piston floating calipers and sintered metal brake pads, and a 240mm (9.4in) single-disc rear with a single-piston, floating caliper. BMW anti-lock braking (ABS) is also available as an option.
The fuel tank capacity is 17.3 litres (3.83 gallons) and the excellent power-to-weight ratio will reward GS riders with a touring range of around 200 miles. Once the F650GS has been run-in, scheduled servicing is carried out at 10,000 kilometres (6,000 miles) intervals.
There is also an F650GS Touring model, which comes with hand guards, pannier frames, panniers and inner bags, a top case holder, top case and inner bag, and a high windshield.
