The bags hitting the shocks on these bikes is really nothing new. The bags on my '04 also came into contact with the canister. A 1" piece of fuzzy velcro on the bag at the contact point solved that issue, just like a couple of large flat washers underneath the front bag mounting bracket has done on the '12. Unless people are using the sleeves that come in the box with shocks, which would push them outward and into the bags more, I can't believe there is that much tolerance variability bike-to-bike that there would be that much of a repetitive fitment issue, particularly with the one model year. The contact with the grommet was so slight, that I probably didn't really need to do anything, as there is some "flex" in the shock bushings that allows the canister to move a bit. I just thought it would be a good idea to shim the bracket for whenever I had a load in the bags, which would tend to make them buldge a bit.
Anyway, very strange. Good luck with your decision.
