Frequently asked questions about cars and motorcycles
The sprocket is one of the motorcycle components most subject to wear, so it is important to know how to change it. After placing the motorcycle on a stand, put it in gear. Use a socket spanner to remove the nut and take it off. Do the same with the washer and the sprocket, using lubricant if necessary. Now, clean and dry both the washer and the nut, take the new sprocket, and install it. Apply some thread lock to the nut, then reposition it along with the washer, tightening it with a torque wrench.
