LOL. Is it just me or did it look like that was a really slow motorcycle race? It looked like they were all doing about 30mph.
Yah - It did look like a slow corner - Maybe 60.
Once the Yellow flag is out, the riders are supposed to cool down in that area of the track (no passing, etc). So that explains why the other guys are tippy~toe~ing around in the video.
That's at ***LeMans, right? Google~Fu says the average speed for an open class bike during the daytime for an endurance race is around 150KM/H.
Moto GrandPrix bikes can touch 300KM/H on the straights at many tracks. The (theoretical) max on a long enough straightaway is something like 350 KM/H (217 MP/H) for the very fastest bikes.
***Self Correction: It's at Magny Cours (France) - I haven't found speed listings, but the full course is 4.4 Kilometers long, and the winner of the last Superbike race was running 1.37.6 lap times.
