I think what he was trying to say was, "rider error".
Here is a copy of what youtube user "Julian Black" said:
Least you are OK, good for you. My thoughts are you are mostly a motorcycle rider, and a good one! For a maxi scooter the turn looked taken too fast and became too wide and the bike hit some rubble. Scooters are so heavy and have that low weight, when hitting even the slightest bit of loose sand on a lean they slip out from under you, no braking can help, it's like brakes don't even exist. A motorcycle will just kick right back up. Guess that why there are no Dirt Scooters
.I've seen it too many times on LA scooter rallies. Rare to see a well used maxi scooter without some road rash.
Then there's a comment from one "Hussars LA":
according to the rider, front brakes over heated , lost strength he had to compensate with rear brakes cause he was running wide in that corner , and lost the rear leaning to take the corner. you can see him having a moment following the red CBR before passing him . scooter is comfy but brakes endurance is not for canyons...
It seems to me these guys and two others named MTB and Dani M are blaming it on the bike being a scooter. What say you all?
