Ironic photo, since it appears he's riding a Triumph ! ?
Scott was an AMA Grand National Champion in 1974. He raced Triumphs, raced for the Harley-Davidson factory team, then as a privateer. Gary Scott was an excellent professional motorcycle racer, but sometimes he could be a real asshole. I guess he slugged Bill Werner in the mouth once over something? Maybe he deserved it? Scott claimed a few motors, said a lot of words . . . but hey, gotta like the dude 'cause he goes like hell !
