The display showed good.
NAB, it is a 2012. I fat fingered the year.
It will start with a fully charged battery 2 or 3 times. However, if it doesn't start on the first few attempts, it acts as if the battery is weak. The starter turns very slowly. No clicking or no strange noise from the starter. I am near Fort Wayne, Indiana. I usually go to Osborn's in Fort Wayne for things I cannot do myself.
What you are describing seems to be possibly a high amp load problem that gets worse as the connection heats up and gets less conductive. Could be the starter itself, but also is commonly a easier to fix cable or connection issues. Disconnect each battery wire connection, not just at the battery, but the other end of your ground, starter, thermal breaker (little box probably mounted alongside battery box) checking they are clean, corrosion free and resecured tightly. If your starter battery connection had oil on it, remember oil is a conductor and clean it.
You might want to even Google how to do a voltage drop test to check that the cables are still good, only a slight chance the cable is worn out, but still a slim possibility and educational.
If all that tests good, with the bike in NEUTRAL, run a hot lead cable direct to that same same starter positive post and hit the starter button. If she spins like crazy, starter is good and it's somewhere in the wire between. If it deasn't kick over briskly or deasn't do it briskly after two or three times, most likely the starter.
If it's the starter, before you have to remove the whole exhaust, search these boards for tips. I believe your bike is the same as my Cross Country and a big short cut / less stressful tip is to trim the right side of the battery box first so you can only remove the front pipe.
Good luck
