At DMG Motorsports, we present the Fire Power CT14B-4 Sealed Factory Activated Battery (SKU 49-2131) — a maintenance-free AGM power solution engineered to keep your bike starting strong ride after ride. Unlike conventional lead-acid batteries that require messy acid fills and periodic maintenance, this Fire Power battery arrives filled and activated from the factory, so it's ready to install with minimal fuss. Fire Power batteries are built on decades of powersports experience, and this CT14B-4 is designed as a direct, dependable replacement for a wide range of street and off-road applications, including a broad lineup of Yamaha models.
