Over on KTM Talk a post is up with a link to EVERY American rider who has EVER participated in the ISDT/E. The list was complied by Mike Vancil. They are looking for proof reading to insure the list is accurate as much of it was hand typed over the past 40 years and mistakes happen. Should make for fun reading.
Here is the link to the post: http://ktmtalk.com/showthread.php?535281-U-S-ISDE-Team-Complete-List-1913-2016
