I installled a new battery this year and yesterday while riding my bike died. I had no power to start it back and it would not push start. I charged the battery (new this year) and while running the battery voltage drops.

It's the same as a car. The regulator or alternator is bad or you have a broken connection. A shop manual will tell you how to test it and also will give you the wiring diagram.

hey i found this Interactive Battery Tutorial | Batterystuff.com good info on motorcycle batteries

also, what is the voltage on the battery before you start, fully charged it should be like 12.8-13.2, and when starting it should be above 9.5-10. If it is dropping when you start it below, like to below 9 volts, it could have developed an open in the cell. Or, if it was dead when you started, then it may have caused some damage

or, it could also be that your regulator/rectifier not having a good connection...but it is really easy to test the battery so I would start there.

Make sure your cables are clean at the very least.
