Front Sprocket for BMW G 310 GS
MREV-P-000025Front sprocket for G310GS: Heat-treated Chromoly 440 steel for the sprocket that drives the chain. Select a tooth count, spline profile and chain size that match the bike. When the existing front sprocket teeth are worn, inspect the chain and rear sprocket too.
The front sprocket for G310GS mounts on the gearbox output shaft to drive the chain and transfer power to the rear wheel. Distinguish the G310GS front sprocket from parts for larger GS models.
What is Chromoly 440 steel used for?
Chromoly 440 steel is used for the front sprocket, which is CNC-machined and heat-treated. Steel suits the small front sprocket, whose teeth drive the chain through repeated revolutions. When selecting a replacement front sprocket, the priorities remain correct chain-size engagement and a secure spline fit on the shaft. Regular chain cleaning and adjustment also affect sprocket wear.
Selecting tooth count for your riding needs
If you are happy with how the bike rides and are replacing only a worn front sprocket, retain its tooth count to preserve the gearing. To change the bike's response, a larger front sprocket reduces the final drive ratio when the rear sprocket remains unchanged. This model is available with 16 teeth.
Checks before installation
When the old front sprocket is worn, record its tooth count and chain markings before removal to select a suitable replacement. If the drivetrain has been modified, measure the sprocket thickness at the chain-running area and check the chainline to the rear sprocket. Use the currently fitted parts as the reference.

Recorded gearing options
Only recorded pitch, position and tooth options are shown. Final-drive changes must be evaluated against the complete front/rear setup; tooth count alone is not treated as a performance claim.
