Classic Dirt Bike Magazine issue #26 contains an article titled "American Legends of the ISDT. Link provided for a digital view of the magazine. Although not a recognized legend I'm disappointed they did not mention Dale Richardson who was an American from the Pacific Northwest who competed primarily on Triumphs from about 1966 thru 1970 initially on a Triumph and then a Eric Cheney prepared Triumph.
