Roy,
I ordered my touch up kits from Bike Bandit...comes as a 2 pack: paint and clearcoat. My '06 Classic is New England White and Cherry Red; I got both colors from Bike Bandit. The Triumph website has paint codes but strangely, only for the Cherry Red color (not New England White). If all you need is a touch up kit (vs a PPG/Dupont number for ordering quarts, etc) then Bike Bandit or the dealer can get them for you.
**Update: just tried to find the area of the Triumph site where the VIN Search, Technical Bulletins, and Paint Codes were housed but the site has been re-designed (again) ...ANYONE know where or if this info is still available?? I found this on paint codes as a direct link from a Google search: Link Removed but I'm not sure how current it is or if it's being updated by Triumph.
