I feel like this could go on FOREVER! haha as for the bikes, you have to start somewhere and work your way up.... it is like that in any sport. work hard and it will pay off. As for the talk about the jumps being too big and everything.... yeah, every track could down size a bit and work on their risk management, but so could the riders. The track builders made a huge jump, do you have to go for it? No. But you want to win, you want money, you want nice things, you want people to know your name. But do you want to risk your life for all of that? Risk management is tricky in any extreme sport. we all except that, we sign the wavers when we sign up for a race.
