Bring reliable starting punch and maintenance-free convenience to your lightweight motorcycle, dirt bike, or scooter with the YTX4L-BS Maintenance Free AGM 12-Volt Battery. Specially engineered for smaller powersports engines, this compact power cell packs 50 Cold Cranking Amps (CCA) to ensure fast, dependable ignition every time you press the starter button or kick the pedal. Whether you are blasting through off-road trails, navigating city streets, or prepping your pit bike for race day, Yuasa’s high-density internal grid construction provides smooth, consistent electrical energy in a lightweight footprint.Built around advanced Absorbed Glass Mat (AGM) technology, the YTX4L-BS traps electrolyte completely inside porous microfiber glass separators to create a fully sealed, leak-proof, and spill-proof unit once activated. The included pre-measured acid bottle makes initial filling quick, clean, and mess-free. Once sealed, this heavy-duty battery permanently eliminates routine fluid checks and water refilling while delivering superior resistance against severe engine vibration and trail shock. Premium lead-calcium grid construction holds a charge up to three times longer than standard batteries during offseason storage, keeping your ride prepped and ready for action.
