best battery for 400ex?????

[underpowered]

stock is a YTX9-bs

a great alternative is a hayabusa battery

or a YTZ10

the last two are higher output batterys great for built motors, but also a bit more pricey than the stocker

the upgrade is part # YT12ABS not the YTZ10 if you want a direct bolt in, and its higher priced compared to the YT12ABS for the same power.
