Hmm. Well, I think you have answered quite a bit, but I am not sure whether I have understood your answer. Let me try an expansion and see if I have understood this:
"V One R = V One RR + floating rear mount + oneway + 3D clutch"
So you are saying that Kyosho removed the floating rear mount , oneway and 3D clutch from the V One R when they developed the V One RR?
Am I correct to say that the front end did not change at all from V One R to V One RR?
