My '02 ST11000 - I toss a Hele2Wheels XL Clothes Sack ( see: http://www.racerpartswholesale.com/product/1104/Helen_Twowheels_Clothes_Sacks ) across the passenger seat and tie it on with two ROK straps and I'm good to go. Easy and quick on and off, easy to carry to hotel room and it holds more crap than I could ever need on a bike trip. I keep clothes inside of it in camping dry bags as teh Helen can leak in heavy rains despite it's claim to be waterproof. The Honda panniers I keep spares in (tools, maps, camelbak, bike cover, etc) and rarely use them clothes. Stuff that is in there is in there year 'round. Also use for anything I might pick up during the day so I don't have to repack the Helen bag to add stuff. My small tank bag carries camera, ear plugs, knife, pens, apper and crap like that. Finally, I bungee a 12 pack color on top. Usually has some water and a couple of pops in it.
