I am willing to bet that changing out the counter sprocket will be quite easy as most of my bikes I have to take the rear wheel loose anyway to get enough slack off the chain to remove the CS. So if you remove the rear wheel and then remove the swingarm pivot shaft, the swing arm will drop down and then there will be enough clearance to slip the CS off, install the new one and re-install swingarm and wheel and off you go. The design should really help with chain, sprocket and overall drivetrain life right down to the swing arm and wheel bearings as there will not be a shocking load due to cycling of the suspension. I like. Hopefully they have or get all the bugs worked out of the unique clutch design.
Just some dude on the internet,..
