Batteries can read 12+ volts when the bike is parked and no current is being drawn, but if they're not capable of supplying high current, the voltage will drop to a low voltage once you try to start the engine. Making the measurement I suggested is very easy to do, and will rule out a battery problem.

Just read the battery voltage while you're trying to start the engine and tell us what it was. It needs to stay up a volt or so from what it was before you tried to start it.

Always start with the easy tests.
