Is a voltage drop like this in 3 min to be expected?

What you're seeing on the volt meter directly after charging is what's known as a 'surface charge' and is not a true indication of the battery's health. The fact that it's now dropped to below 12v suggests it needs replacing. If you charge it up again, take a voltage reading as you're trying to start the bike. A healthy battery will drop to around 9.5 - 10v while cranking and then recover to 12.5+v soon after. If yours is dropping to 8-ish v and not recovering, then it is probably beyond saving.
Many on here, myself included, would recommend Motobatt as a replacement.
