I received again some nice pictures of American riders with their TD1 powered dirt-track machines in the 1960's.

With all the American readers around it will be possible to fill-in more about these riders later-on (I hope....!)

Fred Edward, Yamaha dirt track

This is Fred after he had won the 1969 Daytona Novice Short track race.

Keith Mashburn, Yamaha dirt track

Keith Mashburn's bike had a Sonicweld frame and was built in 1968. As the tailpipes from the exhausts are smaller in diameter already it is probably already a TD1C engine. same goes for Fred Edward's bike of course.

Hopefully some of our American friends do know more about these riders and when these pictures were taken?
