How's the tree.
Your only arguing with yourself, the rules are if you pass das you can ride what you want that's fine by me.
Some one fancies a super Duke that's fine by me too, same as if they just want a 250 v strom
I suggest if your so set against this you should campaign to have the rules changed.
As for individuals having issues with throttle control, you won't find many bothering to post that they had a really boring ride, got home safe and managed to control hands and feet in a coordinated manner so successfully they didn't crash.
If you can't control throttle I suggest not riding anything.
