Can deep cycle batteries be used on motorcycles? Is there some great battery option or should I just go get the same old yuasa/ autozone off the shelf? Anyone got some knowledge?

 

Why would you want to use a "deep cycle" battery?? That type of battery is normally used when you don't have a charging system to run your electrical needs and re-charge the battery from starting the motor.
