As TOTALLY unbiased express owner, I'd have to say the yamaha.
But seriously, I don't think the honda is that ugly, its worst visual crime is it comes in some staggeringly godawful colors. But it was the seventies, we did that sort of thing back then. It was pre zero toerance drug laws, we had an excuse........
Mine is Blue, probably the best of colors it came in, certainly the easiest on the eye, and if its ugly, I don't know, it gets a lot of compliments whnever I take it anywhere.
I think the pre turn signal models look naked somehow though.
