I've not only ridden Pikes Peak but I've spent a lot of time on Cafe Racers and even tracks in my younger years. From a riders standpoint that is one INTENSE video!!
Yeah he's really working it for every engine revolution and every inch of the track, I heard a rev limiter come in at one stage, the riders ten-tenths and the bikes a humming!
Seemed to me the front wheel was coming up outta some of the corners too.
