Your motorbike is liquid-cooled. What should you be sure you do?

Your answer correctly identified that regularly checking the coolant level and regularly cleaning the outer surface of the cooler are essential practices for maintaining a liquid-cooled motorbike. According to German traffic regulations, particularly the rules regarding vehicle maintenance, these actions ensure that your bike operates safely and efficiently.

Regularly checking the coolant level prevents engine overheating, which is critical for safe riding. Cleaning the cooler surface helps maintain proper airflow to the radiator, enhancing cooling efficiency.

While topping up coolant at every refuelling stop is a good practice, it is not necessary if the coolant level is regularly monitored and maintained, hence why the correct combination did not include it. Keeping the bike in optimal condition not only promotes safety but also helps avoid potential breakdowns and ensures compliance with vehicle safety standards in Germany.
