If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.

No, not if the motorcycle is wired for a 6 volt system. This must be a very old motorcycle.
Some have a switch for 6 or 12V - if not you will "cook" a 6 volt battery using a 12 Volt charger
