Routine maintenance keeps your dirt bike operating at peak performance, and coolant changes are a vital aspect of that upkeep. However, if you own a 2017 Kawasaki KLX110L, there's an important detail to understand: the KLX110L is air-cooled, not liquid-cooled. That means this bike does not use a traditional coolant or radiator system like you'd find on larger, performance-oriented models.

This makes the KLX110L a bit more user-friendly for new owners–there's no engine coolant to flush or refill. Instead, the bike relies on airflow to keep the engine at an optimal temperature, which simplifies overall maintenance and reduces potential points of failure.

Key Maintenance Tips for the 2017 Kawasaki KLX110L

  • No coolant changes required: Since the engine is air-cooled, do not attempt to locate a radiator or drain bolts for coolant—they aren't there on this model.
  • Monitor engine temperature during use: Since cooling depends entirely on airflow, avoid letting the engine idle for long periods and do not operate the bike in extremely hot, stagnant environments for extended times.
  • Keep the cooling fins clean: The engine features cooling fins (visible raised metal ridges on the cylinder and head). Use a soft brush and compressed air to keep these fins free of mud, debris, and oil residue, ensuring maximum cooling efficiency.
  • Don't cover the engine: Skid plates or covers that block airflow can cause the engine to run hotter than intended. Make sure any aftermarket parts allow for proper ventilation.
  • Follow the manufacturer's oil and air filter maintenance schedule: Since these are now your main maintenance intervals, keep engine oil fresh and the air filter clean to maximize engine health and temperature control.

What Makes the KLX110L Unique?

  • Accessibly designed for reliability: The air-cooled engine minimizes maintenance and improves durability, ideal for both young riders and those new to off-road maintenance.
  • Simple mechanical layout: Fewer components mean fewer breakdown risks and less complicated service procedures overall.

If you're coming from a liquid-cooled dirt bike, this difference in maintenance may come as a surprise. Embrace the simplicity—that's a key benefit of the KLX110L platform. Stay on top of routine oil, air filter, and general bike care, and your 2017 KLX110L will deliver miles of trouble-free riding fun.
