Once you have the new battery installed and the bike running, using your meter set to VDc 20, take a reading by the same method you used to prove it was flat. You should have between 13.5v and 14.5v above 2000rpm.
if you don’t see this there is possibly something wrong with your charging system, hence the flat battery.
Theres plenty of help here and we can talk you through any of the steps required to get your bike up and running.
Best of luck.

The year of you bike would help get this sorted.
What you could do is follow the cable off the positive side of your battery till you get to the first component. It should be quite close. Check here for a fuse. It could be yellow or green.edit.
I can’t be sure because I don’t know the model you have but if this has blown, there is sometimes a spare attached to the unit. It will be of the same value and you can just pop the good one in.
If you can use your meter to check the fuse whilst it’s in position it would be easier for you. Just set the meter for “continuity” , test by touching the probes together and checking your screen for a visual on what to expect.
Then put your probes on top of the fuse and see what you have. No continuity, fuse blown and look for the possible spare on the unit.
Or I could be wrong and it be something completely different (ignition barrel etc), but is what I’d do next.
