Here at the Glenn Curtiss Museum in Hammondsport, N.Y. they had photos and the actual motorcycle used to win the World Land Speed Record. This would have been 1901-1908 or so and Glenn Curtiss rode his own V-8 motorcycle. Just look at the length of the handlebars because the engine was so large.
In 1907 this photo was taken of Glenn Curtiss where he broke the unofficial land speed record at 136.36 mph. His motorcycle was a 40 hp V-8 engine with 269 cubic inches. It was his own design and construction. He was on the sand of Ormond Beach, Florida. The actual motorcycle or a restoration/reproduction can be seen at the Glenn Curtiss Museum here:
