There's a local paper classified right now for a 1992 Yamaha "Senco" (my another model code they give, I think they mean "Seca"). In case you weren't familiar, the Seca II was a basic, air-cooled, quarter-faired 600cc standard that was generally a great starter bike with a little extra capability to grow into. Good versatile, comfortable all-arounder along the lines of a Bandit 600 or ZR-7.
If I had the $1,200 to spend, I'd be calling about it. If you call or see it, mind filling me in on how it looked/rode?
