Motorcycle batteries operate in demanding conditions short journeys, frequent cold starts, high vibration environments and, increasingly, start-stop ignition cycles that place sustained stress on the power cell. The Bosch S5A AGM FA121 is engineered to meet these exacting requirements, offering a sealed, factory-activated absorbent glass mat construction in a 12V, 8Ah format with a cold cranking amperage of 115A (EN).
Manufactured in Europe, the Bosch S5A range utilises AGM technology in which the electrolyte is fully absorbed into a glass mat separator, eliminating free acid and enabling the battery to withstand both deep discharge cycles and the mechanical stress of off-road or motorsport use. The sealed, maintenance-free design arrives pre-filled with acid and fully charged, requiring no preparation prior to fitment." The FA121 measures 150mm (L) 70mm (W) 105mm (H inc. terminal) and weighs 2.78 kg. It cross-references directly to the OE type code YT9B-BS. Terminal polarity should be confirmed against the product label prior to installation. Bosch part number: 0986FA1210. Start-stop compatibility is supported by the AGM technology verify suitability against the product label for your specific application. "This battery is one of ten variants in the Bosch S5A AGM range stocked on PartsForMachines, spanning reference codes FA100 through FA109, covering a broad spread of motorcycle fitments and capacity requirements." The FA121 is supplied with a 1-year warranty covering defects in materials and workmanship under normal operating conditions. "Standard delivery: 13 working days within UK mainland. 30-day returns.
Sealed factory activated battery: ready for use, filled with acid, fully charged in Europe Adapted to deep discharge and vibrations: as efficient for short distance trips with frequent starts as for motorsports and off-road applications Suitable for motorcycles (off-road and touring), enduros, scooters, quads, jet skis, snowmobiles and applications with many electrical consumers Installation angle: up to 30° thanks to AGM technology.
Key Feature:optimised for motorcycles and two-wheelers, ensuring consistent ignition power, rapid recharge capability, and stable energy supply for compact high-performance engines and accessory systems.
