Man, what a bummer. I'd hate to buy a bike, fall in love with it (or the opposite order as was with the FJR) and then have something like that happen so soon. It would taint the remaining time I had on the bike, how could you trust it after that unless they found the answer was a simple mistake that was rare. However, that thread having two issues with the rear end so soon isn't a good sign. I really hope Kawi and BMW fix these issues. To me, they take away options just in case GenIII comes out riding like a touring bike instead of a sport touring bike.
(shameless plug: Yamaha, please don't make the FJR less sporty, if anything, increase the lean angle)
