What Causes the Abnormal Noise When Shifting into First Gear on a Motorcycle?
1 Answers
Motorcycle shifting into first gear with abnormal noise can be attributed to the following reasons: Improper Operation: When starting the vehicle, the throttle must be closed to the minimum to reduce the chance of such noise. If the throttle is increased before shifting, most motorcycles will produce this abnormal noise. Clutch Malfunction: As the vehicle ages, the clutch may not disengage smoothly, leading to this noise. This issue is similar to the second reason but can be resolved or significantly reduced through maintenance. Sprocket Wear: Excessive wear of the sprocket, especially the front sprocket, can also cause this phenomenon. This is mainly due to the slipping between the sprocket and the chain.
