Yeah, they all tried different setups and had different acronyms. First one I think was the '82 Yamaha Seca 750, so really not a sportbike, but all the sportbikes got them. None of them worked very well since they screwed up the front brake feel, so they made workarounds. Honda called theirs TRAC, and it worked off the torque generated by a pivoting brake caliper, and Suzuki ran an electronic version into the 90's that was triggered by the front brake switch. Everything old is new again!
