1. Higher RPMs: A larger rear sprocket results in higher engine RPMs for the same speed, which can lead to increased engine wear and potential damage if not properly maintained.

2. Noise: A larger sprocket can produce more noise due to the increased speed of the engine and drivetrain components.

3. Fuel Consumption: The increased engine RPMs can lead to higher fuel consumption, which may result in additional costs for frequent riders.
