My wife had problems with her 2010 SG Trike neck bearings. They were so loose, you could grab the Handle bars and hear a pop when you lifted up on them. I took it back to the Dealer. The service guy told me they had never been set and torqued properly. I checked my 2010 RK because I didn't have too much stuff to remove getting to them. Mine was not torqued properly either. I set mine and pumped it full of Amsoil Synthetic Grease. Feels great now. Don't use a cheap grease that will run in hot weather.
