Shop parts for a 2022 Kawasaki KLX110L Dirt Bike.

The 2022 Kawasaki KLX110L is a legendary compact dirt bike, known for its approachable size and tough, air-cooled four-stroke engine. One detail every KLX110L owner should know: the KLX110L is air-cooled, not liquid-cooled. This means the bike does not use a traditional coolant system or radiator found on most larger off-road motorcycles. Instead, it relies on airflow and oil circulation for temperature management.

That's great news for maintenance–since this model requires no coolant replacement at all. If you're coming from a liquid-cooled background or mistakenly searching for how to change coolant for the KLX110L, you can rest easy: there's simply no coolant to service on your 2022 KLX110L — no drain bolt, no radiator, and no antifreeze to buy or worry about.

Key Maintenance for Your KLX110L

  • Focus on oil changes: The most important fluid maintenance on the KLX110L is keeping the engine oil fresh and at the correct level to ensure your small thumper keeps running trouble-free. Change oil at least as regularly as stated in your owner's manual.
  • Keep it clean: Since the cooling system is air-based, make sure your cooling fins are clear of mud and debris. This permits maximum airflow and helps the engine shed heat efficiently.
  • Check other essentials: While you don't need to change coolant, regular checks of spark plug, air filter, chain tension, and brakes are essential for safe, reliable riding.

Model-Specific Note

The 2022 KLX110L differs from the standard KLX110 in seat height, clutch arrangement and suspension, but both use the same reliable air-cooled powerplant. This simple, proven design keeps your maintenance light, ideal for beginner and intermediate riders–one more reason the KLX110L is a MotoSport.com favorite.
