When Good Bikes Go Bad
Why Motorcycle Batteries Fail
Your Voltage is Irregular.
Faulty regulators or alternators can suck the life from your battery. Check all of the connections and resistance from the regulator to the alternator per your manual.
You're Not Grounded.
A bad ground connection between the frame and your battery can interfere with the charge. Check and clean connections.
It's the Circuit Suck
Often with accessories like alarms or a GPS, a leaky circuit can slowly suck your battery dry. Use a volt ohmmeter to check for leaks of an amp or more, then seek out the source of the leak.
Heat and Bad Vibrations.

Self-Discharge.
Motorcycle batteries self-discharge 1% every day even when they're not in use. Use a trickle charger or battery tender to keep your battery charged and ready to go.
