The chain drive of a two-wheeler is exposed to heavy loads, which is why the drive components should be checked and replaced regularly. Sprockets should be replaced when the teeth become too sharp. After fitting a new front or rear sprocket, it is important to adjust the chain tension correctly.
AFAM offers chainrings made of robust steel, lightweight aluminum and self-cleaning anti-mud sprockets with grooves for better self-cleaning.
Funstion of Rear procket
The rear sprocket of a motorcycle is an essential part of the chain drive. It is attached directly to the output of the gearbox and is connected to the front sprocket via a chain.
How can I tell if the sprocket is worn?
A worn or damaged sprocket may show signs such as metallic rattling noises, worn teeth, a loose chain, or difficulty shifting gears.
smaller or larger chainring?
- Sprocket with more teeth → improved acceleration
- Sprocket with fewer teeth → higher top speed
You also have to consider the gear ratio between rear chainring 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.
To ensure optimal life, it is important that you do not neglect chain care, we recommend a special chain brush.
