Mine is a SR600 so I probably bought it in 86 then. I think I have the owner's manual still but haven't searched. Came in a color called "sea-sprite green" which I still think one of the more distinctive bike colors I've seen. Don't think Cdale has used it much, if at all, since the mid80s.
Didn't Cdale actually begin as a camping supply mfgr? I have a vague memory of them selling conventional tourers (Japanese imports I'd imagine) in camping ads before they became a bike and (nearly catastrophically) a motorcycle company.
I don't claim total recall here at all and could be way off.
