In the affected units, the mounting flange on the rear wheel is at risk of cracking if the bolts are over-tightened. If that flange cracks, "the rear wheel may not remain secured to the motorcycle," which is kind of important considering there are only two wheels on a motorcycle to start with.
The recall affects certain model-year 1200 and 1300 models – including the R1200GS, R1200RT, R1200GS, R1200R, R1200S, R1200ST, K1200S, K1200R, K1200R Sport, K1200GT, K1300S, K1300R and K1300GT – as well as the HP2 Megamoto, HP2 Enduro and HP2 Sport. Owners of the affects units can expect to head from the manufacturer to arrange having the aluminum flange replaced with a steel one.
