side covers changed, is one set of bike Pro Tec and the others someone elses.
All three bikes are owned by the same person. The third bike has Fox Factory Forx and the other two are the same bikes from the previous photos. I believe the newer FIM style side-panel and yellow backgrounds were required for use in either the 4 Stroke World Championships or possible the CMC Golden state series.
I'm not sure if that's Magnum P.I., but I'm pretty sure the guy standing behind bike number 30 is Higgins.
