So the overall goal of my 81 cx500c is to have a very board track racer inspired look. The biggest thing for me visually is how small the rear tire is. I would like to modify it to fit a taller tire that would come up behind the rider more. I have considered the cx650 swing arm swap with the cx500 seventies rear wheel which is larger. I know its ambisious but I would love to match the front and back wheels size wise. I am looking for tall tire look not fat. Are these viable ideas or just a big pain in the but. Also if anyone has any ideas on how to help me achieve this look, that would be great, I am a pretty good fabricator but if I can learn from your experience that would save me from doing things over or the wrong way.
