What Are the Cooling Tips for Air-Cooled Motorcycles?

[DeHarley]

Air-cooled motorcycles can improve their cooling capacity by replacing high-quality lubricating oil and cleaning the cylinder head cooling fins. Installing a properly sized fan and adjusting its direction can provide auxiliary cooling. An oil cooler can be installed along the direction of the engine lubricating oil flow to assist with cooling.

After riding motorcycles for so many years, I've learned some tricks for air-cooled bike heat dissipation. The key is maintaining a reasonable speed while riding—going faster allows wind to blow over the engine for cooling. Avoid prolonged low-speed crawling or idling in traffic, as lack of airflow causes temperatures to soar. Regularly clean around the engine, especially dust accumulated in the cooling fin gaps that blocks airflow, using a brush or soft cloth. Checking oil levels is crucial—too little oil worsens lubrication and increases engine heat. I find high-quality synthetic oil works better. In cities, avoid rush hour or consider installing an auxiliary cooling fan. Overheating leads to mechanical issues, so I inspect oil and cooling components monthly.
