I can speak to that from a couple seasons of 250 B class Motocross
(late 90's, 2-strokes)
B class is trying to get an A class Pro card...and it was a little harder than I had hoped, lol
I would run an open class occasionally also, which had the 40+ A class guys in it...who still beat my 18-20 year old self... badly.
I eventually realized that I enjoyed walking, and much better than chasing death, lol, as my best days I still couldn't beat those guys...the same A class pros that couldn't win a heat race into a Pro main event, or if they did, they were back of the pack.
It is pretty amazing to experience skill well beyond your own, and first hand.
It's humbling...and a life saver when you're young and 'invincible'.
From there, I figured I'de just stay on the street, and enjoy hooning without flying through the air...at least not as high...and it's added decades to my life!
lmao
