Taken at face value, a 74.x mph average over 2,8xx miles on a motorcycle is extremely impressive to me. Trying to average that in a cage for even 4 hours is a huge challenge, so those numbers are indeed noteworthy. Even though he obviously had to exceed the posted speed limit coast to coast, I'm hoping that he did so in a well maintained bike, well within his personal limits, and with courtesy and respect for traffic and conditions in mind. That is the way I ride and I saw nothing on the trailer to lead me to believe otherwise.
Where I stray is the "support team". That takes a lot away from the feat. To me, averaging 65 mph, but doing it solely by yourself would be far more impressive. No mechanics, no phone call peeps, no logistics peeps, no bird dogs to scope the Popo and take one for the team, no traffic blockers, no spare parts and supply truck. Just you, your machine, the road, and whatever comes next.
Otherwise, its just another form of converting fuel to rotary motion.
If he was riding a push scooter and had a truck with a tow rope pulling him, would that be much different? (<<<<< exaggeration, I'm not THAT stupid.... he he he)
