Yuasa YTX14L-BS — Maintenance-Free 12V AGM Battery
Product Details

OE-supplied AGM (absorbed-glass-mat) powersport battery — the original-equipment battery for most Japanese sportbikes, cruisers and ATVs, sealed and vibration-proofed for motorcycle use.

  • AGM construction: electrolyte is absorbed into glass-mat separators between the plates, so the battery is sealed, spill-proof and can be mounted on its side if the bike requires it.
  • Factory-sealed after activation — no electrolyte top-ups, no maintenance window, no vent tube to route.
  • Heavy-grid PowerPath plate construction reinforced for the vibration profile of a motorcycle or ATV.
  • Cold-cranking amps and reserve capacity sized to the OE call-out — direct fitment for the listed application (see part number in variant title).
  • Ships dry-charged with a separate acid pack (BS variants) — fill, let stand, install. Factory-Activated variants ship pre-filled, sealed and ready to install.
