Who's in the infamous Suzuki TM400 ad?

The Suzuki TM400, arguably the worst dirt bike of all time.  It shows up on nearly everyone's list when asked the question and now has obtained almost legendary status and collectiblity because of this fact.  And if you hoard vintage magazines from the 70's no doubt you have seen this ad, or even if you don't you have seen this ad floating around on the internet.  You can google the history and controversy (on its handling and power delivery) if you want to know more about the bike itself.  This post will center around the people within the ad itself.  This info-graphic identifies some of the people that lined up for the Suzuki TM400 photo shoot.  From extensive searching magazines, the internet, forums and talking with people here is the who's who in the ad.
