Motorcycle batteries face demanding conditions: frequent cold starts, vibration, and the sustained power demands of modern electronics. The Bosch S5A AGM FA125 is engineered to meet these challenges, providing a sealed, maintenance-free 12V 12Ah power source for a wide range of motorcycles, scooters, and powersport applications.
Manufactured within Europe to Bosch's AGM (Absorbent Glass Mat) specification, the FA125 arrives factory-activated filled, charged, and ready for immediate fitment. The AGM construction immobilises the electrolyte within glass mat separators, delivering enhanced resistance to vibration and deep discharge compared with conventional flooded designs. This makes the battery equally well-suited to short urban commutes with frequent stop-start cycles and to more demanding motorsport or off-road use.
The FA125 operates at 12 Volts with a 12Ah (C20) capacity and a Cold Cranking Amp rating of 210A (EN). Physical dimensions are 133mm (L) 90mm (W) 164mm (H including terminal). Polarity should be confirmed against the product label prior to fitment. The FA125 carries Bosch part number 0986FA1250 and crosses to YTX14AH-BS, YB14-A2, and YB14-B2. The technology supports start-stop systems; verify compatibility against the product label. Weight is 4.4kg." The Bosch S5A AGM range is available in multiple capacities related SKUs include FA100 through FA109 allowing selection of the correct battery for different engine displacements and electrical loads. The FA125 is supplied with a 1-year warranty covering defects in materials and workmanship. "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.
