BMW is launching a service campaign for 440,000 motorcycles of the R 1200 GS and R 1250 GS models to eliminate the problem associated with the gimbals drive. According to the manufacturer, special vent valves will be installed in the rear suspension swingarms of motorcycles coming off the assembly line between 2013 and 2021.
The procedure will be carried out by official BMW dealers. For this purpose, they will drill a hole in the swingarm next to the crosspiece and install a valve into it, allowing air and moisture to escape from the cavity of the swingarm and preventing air and moisture from entering inside. The manufacturer assures that if your motorcycle Cardan is still intact, there is no need to hurry to the dealer – it can be done during the next service.
According to information from the German edition Motorrad similar defects in the Cardan drive system Paralever also exists on the tourer R1200 RT and R1250 RT, also produced since 2013. But the “Goose” problem is more acute, because they, firstly, have more suspension travel, and secondly, these bikes are more often off-road.
