Ok so here are some insane videos that I have found about the isle of man TT and just basic flat out big balled riders. I'm surprised they can even stay on their bikes with balls as big as they have. The second video provides a really great first person point of view of a rider. Highly recommend watching it also.

P.S. kinja has been beyond horrible, so I deleted the old post and am making a new one. If it does not work this time, I will throw my computer out of the window, and never return to this site again.
