How Often Should a Motorcycle Sprocket Be Replaced?
1 Answers
When the teeth of the motorcycle sprocket become sharpened or the chain and teeth do not mesh well, it should be replaced. Functions of the Motorcycle Sprocket: 1. Energy Saving: When a sprocket is installed on a motorcycle, the driving sprocket, through the chain, drives the driven sprocket and the outer wheel, which then engages the inner sleeve via pawls to rotate the rear wheel and propel the motorcycle forward. 2. Reduced Resistance: When the throttle is closed, the rear wheel continues to move forward using the motorcycle's inertia, automatically disengaging from the sprocket and transmission system of the energy-saving sprocket, eliminating the resistance from the transmission system and engine that was passively dragged during inertial travel. Background of Motorcycle Sprockets: Currently, most motorcycle sprockets are of a one-piece structure, where the transmission gear disc and the wheel hub are connected and rotate together. When the engine is turned off, the motorcycle can only operate if placed in neutral, and it is not possible to coast by closing the throttle at any time, whether on flat ground or downhill. For motorcycles, due to their slower speed, this not only wastes fuel but also increases engine wear, reducing the engine's service life.
