Wouldn't it be nice to stumble on such a thing? I was talking to a guy at CD5 who'd scored a brand new CR125 (76 or 77 model I think) some time back, and you keep hearing rumours that such things exist around the place. I often wonder what you'd find if you had a browse through a bike shop in a small town way out in the backblocks, one that had been open for say 30 years.
But what do you do with a bike like that? Keep it pristine as an 'investment', or ride it? For me I guess pristine is an option, but sorta so what? If I race it, then it's pretty soon another tatty old vmx bike (as pretty much what happened to my HL500 and Husky CR500). I think you'd have to keep it as is, otherwise there is really nothing all that secial about it.
Hmmm.... Nice to dream about, anyway.
