I found many article explains RKP with word “better geometry” therefore use on longboarding for satbility.
none of the articles I read explains what better geometry is,
But I think it comes down to trucks movement in relation the the deck.
RKP moves back and forth in order to turn Where as TKP moves up and down in order to turn due to the position of Bushing, hence “Geometry”.
I think this difference what makes TKP not stable since u will be more divy(up and down) which body will be hard time balancing in high speed.
Also I think RKP dampens vib more as the pivot stays angle and let bushing takes more impact.
Is this right?
