TYKOOL
The TYKOOL battery is a direct-fit replacement for the Kawasaki Ninja 400, matching the required YTZ7S spec that the bike runs from the factory. It drops into the battery compartment without modification and delivers the 130 CCA needed for reliable cold starts on the 399cc parallel-twin. Sealed AGM construction means no maintenance hassle. Caveat: longevity reports beyond one to two seasons are limited, so keep your warranty info handy.
