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.
