To change the battery on a Yamaha R1, first ensure the motorcycle is turned off and parked on a stable surface. Remove the seat or side panel, depending on the model year, to access the battery compartment. Disconnect the negative (-) terminal first, followed by the positive (+) terminal, and then remove the old battery. Install the new battery by connecting the positive terminal first, then the negative, and reassemble the seat or panel.
