It can be done. I include a few pics with the hugger on.
You will also need to order the mounting hardware: a bracket (46627671618), a bush (46628543238) and some screws and washers. I found that the hugger touched the number plate when the suspension compressed over big bumps, and took it off in fear of it breaking. This was with the stock UGS suspension. I now have a Wilbers rear shock and will try fitting it again. The new shock is way better that the stock one and I think that it may not touch since the new suspension has compression adjustment. If that works, I'll update this thread. The UGS has slightly more clearance that a Classic, so check the clearance if you have a number plate in the standard position. I also tried spacing the numberplate further away from the bike with 5mm spacers, but that did not solve the issue. I also tried removing some of the excess plastic under the numberplate for additional clearance. In the first you can see the spaced out plate and "shorter" plastic.
It did help a bit for a cleaner back, but not much as the R9T rear tire is slightly wider that the GS and sticks out on the left side.
