Mate - replied to your other comment without seeing this one first and I note now that it is a "RED" bike.

Looking at http://www.ajsutton.co.uk/ the side panels are reasonable at �40 each, but the sticker kit is �126!!!!!!!!

There is a red tailpiece on ebay for �35 which are about �40 new. A new Front fender is about the same price and I now understand the �300 price tag, it's all in the sticker kit!!

As an aside, from my observation only, there appears to be more blue/black in the UK than any other colour which reduces the opportunity to find good quality used items over here.

Good luck with the search.
