How do you use Harley Davidson heal shifter?

To use a Harley Davidson heel shifter, first ensure the motorcycle is in neutral or stopped before shifting. Place your left foot on the heel shifter lever, which is located on the left side of the footpeg assembly. To shift up, push down on the heel shifter with your heel; for downshifting, use the toe shifter as usual. It's essential to coordinate the shift with the throttle and clutch to ensure smooth gear changes.
