Welcome! Congratulations on your new BA. I just got my 2005 just a month ago. I loved the look of the bike after seeing the 2002 when they were introduced...waited three years to get it. The Back rest from triumph is pricy but I like it better than others I've seen...there is a thread here called "other Mfgs accesories that fit our bike's" rumor has it that if you want a memphis shades wind screen you need to order the mounting kit for the Susuki VZ800 Murader...as far as the bags I have the Triumph bags and they are very small...many others here use the easy brackets for their bags and pretty much any bag you like that looks right.
