Just a heads up, the guy is dead.
Roper was killed on June 1, 1896, while testing a new steam motorcycle at a bicycle track in Cambridge, Massachusetts.
... (from link below)
By 1896, Roper felt he had his new machine perfected. On June 1 of that year, he took the steamer to the Charles River bicycle racetrack in Boston to test its viability as a pace-making machine for bicycle races.
Roper made a few exhibition laps around the track and several bicycle racers attempted to keep up with him but were unable to do so. Initially, Roper covered a mile in two minutes and 12 seconds. He was so elated, that he decided to try for an even better time. He scorched around the 1/3-mile wooden track, but he went into a big wobble on the back straight and was thrown off the track and into the sand surrounding it. When the spectators rushed up, it was apparent that Roper was dead. It was later determined that he had died of heart failure, not as a result of the accident itself.
(ADDED NOTE: 1mi/132 seconds *60sec/min*60min/hr =
27.27miles per hour! Not bad for a 72 year old man utilizing steam power! I wonder how fast he got it going that second time around.)
LOL, even this guy had a run in with the local police:
"
Roper was once arrested on one of his rides, but quickly released when it was determined that he had broken no laws."
Also of interest (because of high MPG):
The collection is completed by a 1982 Rifle/Yamaha, highly modified for fuel efficiency. Powered by a 185-cc, 4-stroke engine and completely enclosed in a 19-lb. aerodynamic fiberglass fairing, the 175-lb. bike achieved an astonishing 372.22 mpg at the 1983 Vetter Fuel Economy Contest in California.
