The size of the chain used in a motorcycle engine is determined by several factors, including the power output of the engine, the weight and type of the motorcycle, and the design specifications of the manufacturer. While there isn't a specific CC (cubic centimeter) limit that dictates the largest size chain that can be used without damaging the engine, there are general guidelines and industry standards to consider.
Motorcycles typically use either roller chains or O-ring chains. These chains are designed to handle different power outputs and loads. The size of a chain is typically denoted by its pitch, which is the distance between the pins in the chain.
To ensure that the chain is appropriate for your motorcycle's engine, it's best to refer to the motorcycle manufacturer's specifications or consult a knowledgeable mechanic. They will be able to provide information on the recommended chain size and any limitations specific to your motorcycle model.
Additionally, keep in mind that using a chain that is too large for the engine's power output and design specifications can lead to excessive stress on the engine, increased wear and tear, and potential damage to the chain itself. It's crucial to choose a chain size that matches the intended use and capabilities of your motorcycle to maintain optimal performance and reliability.
