Those are too big for an R65, impressive though they may appear. Be careful about what you buy on ebay - verify unless you are positive it is the thing you want!
Feel free to ask around here if you need a 2nd opinion.
Yes, technically, the R65/R45 models use a slightly smaller diameter headlight assembly than the R80/R100 - I don't have the exact measurement but it is between 6 - 7 inches, maybe 6.75??
And, what are you looking at headlights for when you need a clutch lever & cable?!?

LOL - I don't think that I'd buy anything from anyone with the handle of "super jerk" regardless of how desperate I might be!
