Cool bike rider tattoo

I don't know who this bike rider is representing, but it is really neat. It seems to be some type of guru or rock star, but I can't quite come up with who it is. If you know leave it in the comments below.
It looks like a guy from ZZ Top, but I'm not sure
Either way, it is really done well, and shows again the quality of artists able to do this type of tattoo detail.
