I am amazed at the people searching for a pretty rare motorcycle and then wanting a certain color combination. The last guy was a couple of weeks ago wanting a blue S4R and he found one right away ! I was pretty surprised. When I was looking a couple of years ago, it took a while to even find one for sale at all. It was white and I wasn’t too sure I’d like it until I saw it in person. White with red stripe, red frame, black wheels. It was really sharp. I had no problem pulling the trigger.
To me, the biggest caveat on an S4RS is the condition of the fuel tank, because many have expanded by now, damaging the tank. Replacements are expensive and color choice won’t even matter any more. Alloy replacements are a fortune, and you will then have to paint it anyway.
