Thanks for the welcome Steve. I guess my post was a rant at the current Centa drive being repeatedly described incorrectly in literature and by my dealer. To me there is a big difference between a mechanical addition using mass to balance tortional pulses such as the harmonic balancer used on Harley engines and a device that cushions the transmission with an elastic coupling.
I gather the second incarnation of the compensator was a big improvement on the first although still not silent but the flex Centa drive a significant further leap forward.
