The timing for sprocket replacement is very ambiguous, as there are no clear standards.
Among these, "tooth wear" is a key indicator.
If the teeth become pointed, or the belly or sides are worn down, it's time for replacement.
Replacing only one of the three components—front and rear sprockets and chain—will cause the new part to wear out prematurely due to the old, worn parts. Therefore, considering the long-term, replacing all three simultaneously is recommended for better durability.
Front sprocket (engine side).
Made from S45C (high carbon steel), known for its light weight and high durability.
Sprockets are consumables.
As a general guideline, inspect your sprockets every 1000km of normal driving.
(Regular lubrication significantly extends the lifespan of sprockets and chains.)
The larger the reduction ratio (rear sprocket teeth ÷ front sprocket teeth), the more acceleration-focused; the smaller the ratio, the more top-speed focused.
