How to Solve the Chain Noise Issue on Benelli Leoncino 250?

For this situation, it is often caused by the motorcycle being left outside in the rain, leading to chain rust. Applying lubricating oil to the chain and rotating it a few times should resolve the issue. Check if the chain cover has any dents or warping. If so, the cover needs to be completely removed and the dents or warping should be fixed.

I often encounter chain noise issues on the Benelli Leoncino 250, mainly due to a loose chain or insufficient lubrication, causing rattling during operation. The solution is simple: use a wrench to adjust the chain tension, with the standard being able to press down about 10-15mm in the middle; then apply specialized chain wax or oil—avoid using regular engine oil as it attracts dust and worsens the problem. Additionally, check if the chain is stretched or the sprockets are worn—measure the chain length with a ruler, and replace it if it's too long. Develop a regular maintenance habit, cleaning and lubricating every 2,000 km to prevent noise and extend chain life. For the Leoncino 250, the chain is the core of the transmission, so timely maintenance avoids engine damage or handling issues—safety first.
