I have a 92 CBR 600. I have purchased 2 new batteries. Bike cranks up fine and I can ride for about an hour then it goes dead. I have to charge it again in order for it to run again. It's clearly not the battery. What else could it be?

Hi, asuming the battery is in good condition and has no dead cells, sounds like you have a charging problem, this could be simply a loose conection caused by corrosion, check the plug at the regulator rectifier, gently pull on the wires at the plug on both ends, look for corrosion, separate the plug and check inside it for corrosion, clean if ness, running a motorcycle with a discharged battery can cause damage to the machines electrical systems, including frying the ecu and stator, under normal conditions a. Battery can last up to 3years, (some may last longer) if in any doubt replace the battery
SOURCE: Bike cranks and runs fine,
Sounds like an alternator or charging problem.

Check to see if you are getting around 14v on your battery with the engine running.
If not you will have to investigate your alternator etc.

Put a charger on the battery for two or three hours. Now start the bike up and use a voltmeter to measure the voltage across the two battery terminals while the engine is running around 2000 rpm. The meter should read around 14 volts. If not, the charging system needs to be checked. If the charging system is working properly then yes, something is draining the battery. You will need to check all the wiring and switches to locate the source.

You need to check the charging current and also the discharging of the battery in the IDLE mode. http://www.fixya.com/cars/r5824824-draining_car_battery_charge Use a multimeter to check the charging current and also discharging rate when the engine is switched off. The alternator and accessories must be checked.
