So, you might be thinking I'll set up my bike with a damn big powerful battery and get rocking down the road. Sorry. Don't do this. A battery and engine have been so closely designed to meet exactly what your bike needs. All those small aspects like polarity, vent tubes etc must match your bike. So stick to the right OEM battery part. But on the bright side manufacturers do have stronger upgrades available.
