2008 BMW G 650 X Challenge
The 2008 MY BMW G 650 X Challenge is one of the best enduro machine designed by the House of Munich, thanks to the BMW Motorrad Air Damping System technology in the cast aluminium dual swing arm rear suspension, and the race-inspired 45 mm upside-down front fork, which offers 270 mm of spring travel. Also, its frame is a steel/aluminium one, that is rigid enough for hard, off-road tracks, as well as offers a low center of gravity, for a more maneuverable machine.
At its heart lies a liquid-cooled, four-stroke, 652cc, single cylinder lump mated to a five-speed manual transmission, and can produce 53 horsepower and 60 Nm of torque.
