I have spoken to a dealer about the new parts on 2005 bikes and he has with DUK put together a great deal on the 2005 Numpty upgrade parts; seat, screen, sidestand and mirrors for £200.
As he is a trader and we have a grey area about their advertising on this board (trade area going up when we can) best not to put his details here, but send me a U2U and I will supply you with the information.
