The wheels on a motorbike rely on motorcycle spokes to keep their shape and stay strong. When a spoke gets bent or breaks, you might see a clear bulge on the edge of the wheel, right across from the broken spoke. This bulge shows up because the other spokes are pulling on the edge. Because of this, the wheel doesn't look the same as before. Plus, when the spokes don't have as much tension, the edge of the wheel can get damaged easily by stuff on the road, like potholes and sharp curbs.
To fix a spoke, you need to work on a bare wheel edge, which means taking off both the tire and the inner tube.
The rim strip goes around the outside of the wheel edge. Its main job is to protect the inner tube from the sharp edges of the spoke holes and the hard surface of the wheel edge. If you take off the rim strip, you can see the spoke holes in the wheel edge, making it easier to get to and fix the spokes.
Before you start, put a little bit of linseed oil on the threads of the spoke nut. The spoke nut is a different part from the spoke and is used to attach the spoke to the wheel edge. Putting oil on the threads makes it turn smoothly and helps stop damage when you're putting it in or adjusting it.
Use a spoke wrench to hold onto the side of the spoke nut. Turn the nut the other way around a clock to loosen it. The aim is to make the tension of the new or fixed spoke the same as the other spokes on the same side of the wheel.
To see if the spoke tension is right, flick the other spokes on the wheel and listen to the sound they make. Then, flick the spoke you're fixing. Spokes with the same tension will make similar sounds. Keep adjusting the nut until the sound is the same as the other spokes, which means the tension is right.
If you do these steps carefully, you can fix a broken spoke on a motorbike wheel, make it look and feel right again, and ride safely.
