Having owned and lightly raced sport bikes back in my younger days I can say
These videos are soo scary for me to watch now, the speed and bumps. Easy to get in to a tank slapper and become a decoration on one of those fences or buildings lining the course.
These Guys are such good riders, they make toying with death (e.g: Jumping off bumps at 170+mph) look easy.
I love the Isle of Mann TT.
Its a must watch for me.
