Motorcycle Chain Noise — Advance Concept behind this problem

Motorcycle chain noise is not always caused by poor lubrication or wrong adjustment.
In many cases, the real reason is chain wear leading to length increase and sprocket mismatch.

As a motorcycle ages and mileage increases:
The chain gradually wears internally
This causes an increase in effective chain length
The worn or old sprocket teeth no longer match the chain pitch correctly
This mismatch creates continuous chain noise, vibration, and uneven power transfer

In such situations:
Chain adjustment formulas stop working
Lubrication provides only temporary relief
Even a new chain can produce noise if installed on worn sprockets
What you’ll learn in this video
What chain wear actually means (not stretching, but internal wear)
How chain length increases over time
Why sprocket mismatch creates noise and vibration
Why adjustment alone cannot fix certain chain noise problems
When replacing the chain and sprocket set together is the only correct solution

Applicable for
High-mileage motorcycles
Older bikes
Heavy riding and touring motorcycles
Bikes with chain noise even after chain replacement

Important note
If the wear pattern of the chain and sprocket does not match,
no amount of adjustment or lubrication can permanently solve the problem.
