What is shifter for motorcycle?

A shifter for a motorcycle is a device used to change gears while riding. It is usually located on the left side of the motorcycle beside the footpeg. When the rider uses their left foot to push the shifter down, the motorcycle shifts into a lower gear, and when they lift the shifter up, the motorcycle shifts into a higher gear. Some motorcycles may have a more advanced shifter, such as a quick shifter which allows the rider to upshift without using the clutch or a power shifter which allows the rider to shift gears with a button. It is important for riders to become accustomed to using the shifter to ensure a smooth and safe ride.
