Nice pictures and report... sorry for your mis-adventures , but seems that Honda are generally weak about rear wheel bearings , during the first Dolomites AdvRally Bummer's transalp destroyed the bearing just like yours - and had just more than 30k kms! - fortunately was able to source SKF bearings on place and a friend with a lathe re-made the shims ... the next one the Slovenian Africa Twin rider broke too his bearing , but he knew very well his bike and had the spares in the bag..
