But if your bike has ABS and Traction control then you need to alter the front signal from the pick up to compensate for the bigger slower turning wheel.
Think you got it backwards here, they say the gadget was for newer bikes without servo assisted brakes, not the older bikes that had it. Would be stupid for Wunderlich to say "dont ever use the 21" kit on a 2007 or newer bike" if they think the adapter is no longer needed.
