The recall covers multiple models including the 2005 to 2010 R1200 GS and R1200 RT, and the 2006 to 2010 R1200 GS Adventure.
BMW says if bolts that hold the rear wheels to a flange are over-tightened, the flange can crack. If that happens, the bolts can loosen and the wheel may not stay secured to the bike.
The problem was discovered after a 2004 motorcycle crashed in Spain last August. BMW says the rider and passenger were bruised and scraped.
