As standard, BMW has the R100 model. models come with a conventional 12 V, 24-28 Ah, 130 A battery. However, since I don't use the radio, blue light or siren, the 12 V, 20 Ah, 190 A is completely sufficient, especially since the gel battery also lasts much longer than a conventional lead battery and is much easier to install than the larger original battery. I can fully recommend this battery.
