    Final note: Batteries can be dangerous to you, people around you, and your motorcycle's sensitive electronics. Remove all metal jewelry before working. When in doubt, take your motorcycle to a reputable dealer.


    Removing or Changing the battery on your BMW F-Twin (F650, F700 and F800)

    Note 1: The specific bike shown is a 2013 F800GS, but the battery removal should be applicable to all twin-cylinder F650, F700 and F800 bikes and models. How you get to the battery will be different on other styles of F-Twins (ST,GT)
    Note 2: This F800GS has been heavily accessorized (farkeled), which results in many more battery connections and excess wires compared to a stock bike. This bike also has an aftermarket battery installed with two additional terminals.
    Note 3: The tools and materials used are by personal choice and are not due to any affiliation with any brand

    Tools Required:
    - T25 star (Torx) bit
    - T27 star bit
    - 10mm socket (or equivalent that fits your specific battery terminals)
    - Ratchet(s) that fit the above
