@thebatmanbiker, both have similar challenges but are different at the same time.
since im not a fighter jet pilot, and doubt there is a bunch of them in here. i will go ahead and state that motorcycle is more difficult since it requires more interaction for a longer period of time, where as a jet pilot is limited by how long they can fly and most likely don't fly alone or have a ton of support in the ground.
motorcycle racers are one with the machine much more so than a fighter pilot i would imagine.
