In this video tutorial, you will learn how to remove and replace the transmission sprocket on the Beta RR 125 enduro bike in simple and quick steps. First, unscrew the screw of the sprocket cover to access it; then unscrew the two fixing screws of the sprocket, loosening the chain first (by unscrewing the nut of the adjuster found on the rear swingarm), as shown in the video.

At this point, replace the sprocket with the new one that has the same tooth count; then reassemble the transmission by applying the reverse procedure!
