- The chain has stretched beyond the recommended limits specified by the manufacturer. You can check the chain's stretch by measuring the distance between a certain number of links and comparing it to the specified value in your motorcycle's manual.
- The chain shows visible signs of wear, such as kinks, cracks, or broken links.
- The chain is rusty or has excessive corrosion, which can weaken the chain and reduce its lifespan.
- The chain is making excessive noise, which can be a sign of wear or misalignment.
- You experience problems with shifting gears, which can be caused by a worn or stretched chain.
- The chain skips teeth on the sprockets, which is a dangerous situation and requires immediate replacement of the chain and possibly the sprockets as well.
In general, it's recommended to replace your motorcycle chain every 15,000 to 25,000 kilometers (9,000 to 16,000 miles) as a preventive measure to ensure safety and optimal performance.
However, the actual replacement interval can vary depending on factors such as riding style, chain maintenance, and environmental conditions.
