I have recently bought some mc21 fairing parts from david silver And they were pretty cheap but I think the stuff is cheap because they buy up old stock at discounted prices.I reckon if they ordered it in special it would be normal price but it would be worth asking and they are always easy to deal with. Check out their web site, you can download the stock list and trawl through it to find nsr parts. They didnt have any rothmans stuff when I last looked (if they did it would be on my bike).They have got some mc21 petrol tanks, exhausts and other bits and bob's and lots of mc18 bodywork. The bodywork does come with all the decals applied, but if your bodywork is good you can buy all the decals individually but again this can add up to a lot of money as well, I was quoted about £40 + vat per side for the yellow side decals that go on the seat unit on a pentax replica!
