Other than price there is no down side to this battery. The one I have is rated at 270CCA, weights 2.1pounds, and is expected to last 2 to 4 times longer than a lead acid battery.

The only issue with the Lithium Iron battery that I know of is cold starting. When very cold they recommend turning the ignition on, but not starting the bike for a couple of minutes. With the power draw from the headlight and ignition it will warm the battery up and increase it's CCA, which is the opposite of a lead acid battery.
