Mark what frame is your bike, an SS? I'm trying to replace my seat unit with an enclosed one too. Matt larett's got a Cbr 600 tail fairing that I think looks good.
Skids what is that seat unit in the picture and I take it the bikes an SS too? Also it looks like its fixed from under the seat foam which I take it means the foam needs to be removed each time you need to take the seat unit off or I suppose you could have a couple of access holes in the foam. Either way are there any good places to get them from other than the obvious eBay?
