You know about rock climbing? Sure you do. Some people do it to relax and exercise, some people go rock climbing just to get away and some… well, some people go rock climbing to ride motorcycles. Their skill is out-of-this-world crazy! The sense of balance, the courage, everything. They are the trial riders. On their feather-light motorcycles, packed with explosive engines, they do the impossible. And just how impossible? All I know is that if you put me on a motorcycle running towards a wall, I’d become street art – these guys, they just go over it.
