Finally got around to scanning this book I had at home. It chronicles American motorcycle racing from the 40s to the 80s with great photos. A good book to check out if you're into this sort of thing.Below is William S. Harley (older gentleman in suit in the middle) and Bill Davidson (far right).
Above is a 1966 CRTT 250 Harley Davidson Sprint and it randomly made me think of my friend Len's bike that he built (pictured below). It just one Best Original at the Born Free Show this past weekend.
