Kruzer,
I assume you mean wheel bearings. I have about 8,000 miles on my 03, about 1,000 of it in the rain. I have not had any wheel bearings fail. There was a batch that were bad, and it showed up sooner on the ones that were driven in the rain. I check the grease every time the wheel comes off, it's not that hard to do. If you plan on a fair amount of rain riding, regardless of what bike you own, keeping up on the lubicration is more critical. Rain riding is like power washing your bike, only for a longer period of time, and does wash away lubricants.
