I used to have a trials bike in my twenties. I watched the experts do their stunts and thought I could do them too. I did two things well. Falling off and hurting myself! Great fun though!
I used to try to do this with my YZ450F. There are 4 important things you need to do this. Anti Gravity tires, the inability to see impossibility, more practice time than work time, and wicked skills. I lacked the first 3 key ingredients and have decent skills.
