BMWG650X Challenge 2007 - 2008

　　In 2007, the German motorcycle manufacturer launched the BMW G650X Challenge, one of the best enduro motorcycles designed by BMW Motorrad. The bike featured BMW air damping system technology on the cast aluminum swingarm and a race-inspired 45 mm USD fork on the front.

　　The bike debuted in 2006 alongside the G650X Moto and the G650X Country. All models packed the same engine made by Rotax in Europe, while later, BMW switched to Loncin in China. The engines were sent to Italy, where the bikes were assembled.

　　In the visual department, the machine packed standard features, such as a small headlight, a high-mounted fender, a one-piece single seat, a high-mounted exhaust system with a massive muffler mounted on the left side, and wire-spoke wheels shod with off-road tires.

　　In the suspension department, the bike packed a 45 mm upside-down telescopic fork on the front with 270 mm wheel travel and a single shock absorber on the rear with 270 mm wheel travel, offering excellent off-road handling.

　　The braking performance was achieved by a 300 mm disc coupled to a dual-piston caliper on the front wheel and a 240 mm disc squeezed by a single-piston caliper on the rear wheel, offering excellent stopping power.

　　As for the power figures, the 2007 BMW G650X Challenge had its heartbeat set by a 652cc four-stroke single-cylinder liquid-cooled engine fed by an electronically controlled fuel injection system, boasting 53 hp at 7,000 rpm and 60 Nm (44 lb-ft) torque at 5,250 rpm.
