What year was that? I'm pretty sure in 1980 when MotorCyclist tested the Kawi,Honda,and Suzy 750's, the Kawi KZ750-4 was the faster 1/4miler. Maybe the Yammie 750trip was included. I owned the Kawi
I don't doubt that. For some reason, the K-1 CB 750s were the fastest years ('69-70?) for Honda. They got slower after that. I've been told it was due to EPA camshaft changes for smog but I don't know that to be true.
