These steel sprockets provide the listed 1979–81 standard-CB650 choices. A previous gearing change, different wheel or chain conversion needs checking before the original application can guide your purchase.
The selected sprockets are for 530 chain, with 16 teeth at the front and 40 at the rear. Verify both fitted sprockets and the chain before ordering. Do not mix a single replacement into a different chain-size conversion on the strength of model year alone.
Separate retention hardware
The front lock-plate set includes the plate and two bolts. Compare the old retention hardware during sprocket service and follow the applicable service instructions. The set is a separate item; the sprocket listing does not establish that it is included.
Ordering questions
What should I check before choosing a replacement sprocket?
Confirm that the chain and both sprockets use the same 530 specification. Count the fitted sprocket teeth, inspect both sprockets and the chain together, and verify the required chain length and adjustment range before ordering.
When should the front-sprocket lock plate be replaced?
Replace a plate that is bent, cracked, worn at the bolt holes or no longer locks securely. Inspect it when replacing the front sprocket and renew damaged retaining hardware as the repair requires.
Can I use these with a different chain size?
Do not assume compatibility with a conversion. These two sprockets are specified for 530 chain; identify the complete fitted chain and sprocket setup before selecting replacements.
