AFAM 60T rear cog for Sherco 50
AFAM 60-tooth sprocket for Sherco 50 models up to 2020; replacement chainring or for changing the gear ratio. AFAM steel sprockets are made from C45 steel and then heat-treated to achieve greater hardness and durability.
Replacing the Sprocket
The rear sprocket should be replaced when the teeth become too sharp. After installing the front or rear, it is essential to readjust the chain tension. We recommend replacing the entire assembly at once including front sprocket and chain to ensure even wear and extend the service life of all components.
Note: Since there may be different variants depending on the year of manufacture, please compare the dimensions and number of teeth on your chainring with the illustration and the specifications provided.

Funstion of Rear procket
The rear sprocket of a motorcycle is an essential part of the chain drive. It is mounted directly on the rear wheel and is connected to the front sprocket via a chain.
How can I tell if the sprocket is worn?
You can usually identify rear sprocket wear by inspecting the teeth. Worn teeth have an irregular shape and appear thin, very pointed or bent. You may also notice metallic rattling noises. Severe wear can cause the chain to skip because it slips over the excessively worn teeth.
smaller or larger Sprocket?
- Sprocket with more teeth → improved acceleration
- Sprocket with fewer teeth → higher top speed
You also have to consider the gear ratio between rear and front sprocket. The calculation is: number of teeth of rear sprocket / number of teeth of front spocket. A low ratio increases speed, while a high ratio improves acceleration.
Example: Front sprocket with 13 teeth and rear sprocket with 48 teeth: 48/13 = a ratio of 3.69.
Sprocket types
Steel is preferable to aluminium if you want the longest possible service life. Aluminium is the better choice for maximum performance because it is lighter. Self-cleaning anti-mud rear sprockets are suitable for off-road use in dirt and mud.
Chain care
To ensure optimal life, it is important that you do not neglect chain care, we recommend a special chain brush.
