Shorai LFX21L6-BS12

Offers the highest levels of stored charge and cranking power. We recommend this battery for high displacement street and adventure bikes exceeding 1000cc, or just large capacity bikes which sit around unused for a really long time in-between startups. Most customers who purchase these batteries are riders of smaller capacity Harley Davidsons and larger capacity Kawasaki models. If unsure about your product choice, contact us for a specific product recommendation for your bike/usage pattern. Expect weight savings of exceeding 5kg over your OEM lead-acid battery.

The Shorai LFX21L6-BS12 is completely identical to the LFX21A6-BS12 except the location of the positive and negative terminals of the batteries are inverted.  The Specifications tab will show this difference in greater detail diagrammatically. 

Shorai Batteries require a charging system output of 13.1 Volts or higher at idle, and must not exceed 15.2 volts at maximum output.
