I bought that rack for the G5 but it doesn't fit the 2011 because they changed the tail light assy and the trafficators are in the way. It would work if you relocated the trafficators but I had to make a custom subframe for the pillion anyway so I incorporated a rack into that instead. It would be much sturdier if I also mounted into the shock bolt like the nfield gear rack does. Yes, I definately upgraded the bolts and went one size up on the two rear bolts but we'll see how the 6mm bolts hold up- they're pretty small.
