When knock is detected ignition advance is dialed back until knock is eliminated. I think some BMW's have this feature so to allow them to run on low octane fuel. Of course BMW's are designed to use high octane gas and this does not apply to most engines designed to run on regular gas like our CB's.Some Hondas do as well. VFR, ST1300 and Gold Wing too, I believe. But not CB1100.
