Now theres a thing, I was just thinking about the fact that there wasn't many posh frames built for two strokes but then remembered a readers special on Performance bikes in about 88? (ish).
It was a 350 powervalve engine held in a frame described as being two bent dural plates that went from the swingarm to the headstock.
There was a bit of pipe that went between them bolted into place under the front of the seat if i remember it right and the owner said that a specialist frame builder had made it but didn't want credit as he didn't need the people ringing up about it, something like that anyway.
Don't suppose you have any idea what the hell I am waffling on about?
Looked nice though.
