A number of failures of the rear disk carrier on R1200GS, GSA and HP2 Motorcycles have been reported by club members and mechanics in WA. There is also an extensive thread on Adventure riders that details numerous disk carrier failures worldwide.
ADV Rider Topic 12GS Disk Flange Cracks

Another article on the subject is here at Motorcycle Info Pages

Within our club 2 members (now 3) have recently reported a disk carrier failure, one of them narrowly avoided serious injury when his rear disk broke away from the carrier and locked up the rear wheel.

One former member has noted that he thinks this should be a matter of safety recall from the manufacturer but so far this has not happened. So they have reported the problem to recall Australia but have been told that they need more complaints before they can take action.

If you ride one of these bikes you are strongly encouraged to check your motorcycle for evidence of cracks in the rear carrier. This is a 10 minute job but requires the removal of the rear wheel. See the posting in the club technical forum on how to do this. If you find a problem please take the time to report it with photos to Recall Australia so that we can prompt them to follow this up.


Below are some pictures showing evidence of the problem. Note later bikes have a steel carrier fitted and may not be subject to this problem. Certainly most problems seem to be on the earlier 04,05 models
