Draining batteries kills them pretty fast. Usually ATV and motorcycle batteries don't last long because people let them die through the winter. Wet cell batteries are not designed to deep cycle. The best way to make a battery last a very long time is to always keep it fully charged by keeping it on charge through the winter or any time the bike sits idle for long periods of time. The first popular automatic float charger was the battery tender, but now automatic chargers are all over the place from local parts stores to Walmart. Don't just get a trickle charger though. Get an automatic charger that won't overcharge the battery.
Another thing I have found is that some vehicles have a significant draw while not running. For example, I have an ATV that kills batteries if left alone for less than one month. I hear the same from everybody that has this particular model. So, it is best to disconnect the battery for long periods of inactivity.
