Motorcycle sidecar racing is one of the most extreme motor-sport events I’ve ever encountered. I can’t imagine the guts it must take to be the guy hanging off the side into every turn, with total faith in the chap holding the handlebars.
In the days before optional ABS and wuss-o-rama-heated-grips they had optional sidecar mounted machine guns. The old days kick ass. I can’t help but think motorists would be far less likely to pull out on front of motorcyclists if these were still fitted. (Click image for high-res version)
