Wow ... that brings back memories. Honda XL250 Motosport. I toured the south island of New Zealand with my wife back in the early seventies on one of those. What a trip ... two days to go and tossed it away coming of one of the strange little bridges they used to have that shared rail traffic. Pouring rain and got all tangled up in the rail lines coming of the end of the bridge and nearly got cleaned up by a car following. My wife finished up in hospital and I completed the trip back to Wellington on my own on a slightly scarred but still ridable Honda.
Racing one of those would have been interesting ... from memory mine wasn't exactly over endowed with speed!
