AMA Pro Flat Track has officially arrived in Birmingham for the 11th Annual Barber Vintage Festival Presented by Triumph Dealers of North America at Barber Motorsports Park!
In the early 1970's there were a few dirt track machines built using three and four cylinder power units, both two and four strokes. This motorcycle was believed to be the only one to use the Honda CB750 motor, and was raced by National No. 31Z Rick Hocking.
