    ATAC was the Honda CR250's first generation "powervalve" system. It stands for Automatic Torque Amplification Chamber and works similarly to Suzuki's AETC system. It's basically a chamber that the exhaust gasses get bypassed thru during certain portions of the powerband. I have no experience with them, and other than the above, I don't know much about them.
