In Oklahoma in 1972 I recall this being the scariest bike I ever got on. I have never felt the need to hold on so tight to the handlebars because it felt like the bike was going to literally fly away from me like some crazy road runner cartoon. Far too light to be much fun in windy conditions I saw one that went down on the interstate cut down by cross wind from an overpass.. luckily the rider literally rode the thing to a stop, drug it to the side of the road and never got on it again. Fantastic acceleration ... legendary.
