One of my Long Distance riding heroes is a guy named Leon Begman. He did all kinds of IBA rides on his Kawasaki Ninja 250. For several years it was painted John Deere green and yellow with the JD deer on the tank. In '03, Leon got into the Iron Butt Rally in the "Hopeless Class."
Ha!
I went up to the finish of the Rally in Missoula (in fact, that's where I met EX-WINGER, Eldon Cannon). On the Friday of the finish, there was a two hour window after the official finish time. You lost lots of points for every minute you were late (100 pts/min, IIRC). At one hour and fifty minutes (only nine minutes before the drop dead, you did not finish time) Leon came into the parking lot on his pick-up-truck-liner black Ninja 250. He had a rider-only Russell DayLong saddle, a huge black Rubbermaid storage box bolted to the pillion area, one (count 'em...1) driving light, and enough excess alternator capacity to run a Gerbings heated jacket.
Leon finished 11th or 12th in the IBR. His storage box wasn't quite as big as the TrailerStar Products Poly Storage Chest Truck Box.
