Re: TA torque reaction-not!
I do not pretend to know everything about torque reaction but from my own experiance I once built a buggy with a quad type swinging arm and put the front drive sprocket dead center on the swinging arm pivot thinking that would be best (no chain movement through the swinging arm stroke) when I drove the buggy it just lift the rear when I accelerated and would not allow the swinging arm to move even on big bumps. Rolling in neutral it worked fine.
This is why they have adjustable swing arm pivot point on road race bikes so you can change how the bike reacts when you put on the power or shut off.
Its sort of like the bike, buggy or what ever trying to rotate itself around the pivot point instead of driving forward.
I hope that makes some sence, I know what I am trying to say !!!
