Iridium spark plugs are known for their durability and longevity compared to traditional copper or platinum spark plugs. While the exact lifespan of iridium spark plugs can vary depending on various factors such as riding conditions, engine characteristics, and maintenance practices, they generally have an extended service life.
On average, iridium spark plugs can last between 40,000 to 60,000 miles (64,000 to 96,000 kilometers) or even more in some cases. However, it's important to note that this is a rough estimate, and the actual lifespan can be influenced by several factors. These factors include the specific motorcycle model, the engine's condition, the quality of fuel used, riding conditions (such as frequent idling or stop-and-go traffic), and the overall maintenance of the motorcycle.
It's recommended to consult your motorcycle's owner's manual or the manufacturer's guidelines for the recommended spark plug replacement interval specific to your model. Regularly inspecting the condition of the spark plugs and consulting a qualified mechanic can also help determine when it's time for replacement. If you notice any signs of poor performance, misfiring, or difficulty starting the motorcycle, it's advisable to check the spark plugs and consider replacing them if necessary.
