Edge of what? Sanity you might say.
Superlatives fail these guys. Fearless. Brave, Crazy. All fall short of what makes these racers tackle a race that may take their life.
The Isle of Mann TT..... Time Trial (or Tourist Trophy) is one of the last free for all races left in the world. World class Moto races strap themselves to bikes capable of 200 mph and race head to head, rubbing tires and body work together at over 150 mph. Or to add to the spectacle, wheelies at 160 mph.
Death and destruction does happen, every year, but the racers and spectators keep coming back. It's obviously addicting.
Enjoy this popular clip that's been around for a few years now, but does a good job of capturing the speed and edge of everything that this race embodies.
