I like the SW Motech racks and wish that they made the rack with the quick lock adapters for their rack, but no such luck on the C14 rack... I have used the Givi adapter and their soft luggage rack when camping in the past on other bikes. The only thing TT lists is a plain rack that needs the $20 kit for mounting a trunk to it, that may be what you were referring to. You will need a rack and the SW kit or the Givi rack is an option as well if you need the extra support and plan to carry heavy items in the trunk. I just bought a Phil's rack for mine with the givi kit already installed.
