The brake systems also differ from one model to another: The single-disc front-wheel brakes on the Xcountry and the Xchallenge each measure 300 millimetres or 11.81´´ in diameter and come in each case with a double-piston brake calliper, while the Xmoto features a four-piston brake calliper interacting with a brake disc measuring 320 millimetres or 12.60´´ in diameter. 

A feature truly unique in the segment of highly specialised single-cylinder motorcycles – but nevertheless quite natural on a BMW – is the optional availability of light and compact two-channel ABS for even greater braking performance. And it also goes without saying that the ABS anti-lock
brake system does not in any way restrict the ambitious sports rider wishing to enjoy himself off the beaten track or on special circuits reserved for racing, since the system may be deactivated on demand. And naturally, the offroad rider enjoying the Xchallenge benefits from the same freedom whenever he – or she – wishes.

Again reflecting the usual standard of BMW Motorrad, the G 650 X models may also be customised by a wide range of accessories and special features tailored to each model.

Indeed, the new models are not only the successors to the former single-cylinder machines, but rather round off the range as a whole, since both the F 650 GS and the F 650 GS Dakar are to remain in the model line-up in 2007, with production continuing at BMW Motorrad’s Berlin Plant.
