Speedmaster Back In The Fold

I am soon to be back in the Triump fold after 2 years on Honda VTX1300 (GREAT BIKE BUT NOT A TRIUMPH).
I have owned 2 Triumphs over the years, a Legend 900 and a Bonneville America. I am hoping to pick up a 2018 Speedmaster 1200 next week and can't wait.
Where is the best site for parts? First in the list is the x pipe cat delete then a sissy bar and rack then a dart flyscreen and maybe a comfort seat. If any one has any of these for sale please let me know thanks

 

Hi Dart player, i pick up in a week to 10 days. Can't wait like an excited child. Yours looks ace.
