The cubic centimeters (CC) of a motorcycle's engine refers to its displacement, which is a measure of the total volume swept by all the pistons within the cylinders of the engine. The CC alone does not dictate the type or quality of fuel required for a motorcycle.
Generally, motorcycles with higher displacement engines tend to have higher performance capabilities, which may necessitate the use of higher octane fuel to prevent knocking or engine damage. However, it's important to consult the owner's manual or contact the manufacturer to determine the specific fuel requirements for your motorcycle.
The manufacturer's recommendations are based on factors such as the engine design, compression ratio, and ignition system. They will specify the minimum octane rating or fuel grade that should be used to ensure optimal performance and protect the engine.
Using a fuel with a lower octane rating than recommended can potentially lead to knocking or pinging, as the fuel-air mixture may ignite prematurely. Conversely, using a higher octane fuel than necessary typically does not provide any significant benefits and may be an unnecessary expense.
To ensure the longevity and performance of your motorcycle, it's generally advisable to follow the manufacturer's fuel recommendations and use the appropriate fuel grade as specified in the owner's manual or by the manufacturer.
