I'm building up a little 1971 Kawasaki KV100 while my cb550 is slowly slowly coming together.
i plan on sort of turning it into a cafe style bike.
I want a longer tank for it, but one thats not too tall/high. and I want to have a shot at wacking knee dents into it

What sort of bikes do you think would have a good tank that i can scrounge wreckers for?
