The replacement time for sprockets is very vague, with no clear standards.
The determining factor in such cases is "tooth wear."
When the teeth become pointed or the belly and sides are worn down, it's time for replacement.
Simultaneous replacement of front and rear sprockets and chain If you only replace one of these three components, the worn parts that haven't been replaced will cause the new parts to lose their original performance and durability, thus shortening their lifespan. Therefore, for long-term effectiveness, it is recommended to replace all three simultaneously, as this will lead to greater longevity.
Front sprocket (engine side).
Made from S45C (high-carbon steel), which offers both lightweight and high durability.
Sprockets are consumables.
As a general guideline for normal driving, please inspect the sprocket approximately every 1000 km.
(With daily lubrication, the lifespan of sprockets and chains will significantly increase.)
Rear sprocket tooth count ÷ Front sprocket tooth count = Reduction ratio. A higher value indicates an acceleration-oriented type, while a lower value indicates a top speed-oriented type.
