I'm an avid motorcyclists. Raced motocross when it first came to the USA in the 60's (on a BSA 441 Victor), do desert riding, off-road adventure riding, enduros, hare scrambles, etc. But when I was loaned a trials bike for a couple of months I about killed myself. Daily. Every time I tried a maneuver.
The pros make it look so graceful and flowing when in fact it is incredibly difficult. I admire anyone who makes the effort to learn to ride a trials bike.
