There is no clear standard for when to replace a sprocket, making it a very ambiguous decision.
A key indicator for this decision is "wear on the tooth tips."
If the tooth tips become pointed, or the belly or sides are worn down, it's time for a replacement.
It is recommended to replace all three components—front and rear sprockets and the chain—simultaneously. If you only replace one of these parts, the worn parts you didn't replace will prevent the new part from performing optimally and lasting as long as it should. In the long run, replacing all three at once is more cost-effective as it extends their lifespan.
This is a front (engine-side) sprocket.
It is made of S45C (high carbon steel), which offers both light weight and high durability.
Sprockets are consumables.
As a general guideline for normal driving, inspect the sprocket approximately every 1000 km.
(Regular lubrication significantly extends the lifespan of both sprockets and chains.)
The higher the reduction ratio (rear sprocket teeth ÷ front sprocket teeth), the more acceleration-oriented the setup; the lower the ratio, the more top speed-oriented.
Compatible models: Monkey series / APE series / NSR50, etc.
