Shop parts for a 2020 Yamaha TTR50 Dirt Bike.

Keeping your 2020 Yamaha TTR50 in top shape means regular maintenance, including changing the coolant. The TTR50, with its user-friendly design and air-cooled engine, doesn't use a liquid cooling system like many larger or newer dirt bikes. Instead, it relies on airflow during operation to maintain engine temperature, which means this model does not require traditional coolant changes you'd perform on water-cooled motorcycles.

What Owners of a 2020 Yamaha TTR50 Must Know:

  • No radiator or liquid coolant: The TTR50 runs an air-cooled, single-cylinder engine. There are no radiators, hoses, or coolant reservoirs to service, which is a major point of difference from water-cooled models like the YZ or WR series.
  • Engine maintenance focus: For air-cooled engines like the TTR50, proper oil changes, air filter cleaning, and checking for any external debris are essential to keep the cooling fins clear for air circulation.
  • Typical coolant instructions do not apply: Guides describing radiator cap removal, coolant draining, filling, and burping the radiator do not apply to this bike model.

Essential Maintenance Steps for the TTR50:

  • Visually inspect the cooling fins for dirt or mud buildup, and clean them gently with a soft brush if needed.
  • Perform regular oil changes as recommended by Yamaha to keep the engine running cool and smoothly.
  • Keep the air filter clean, since air circulation is critical for cooling.
  • Never attempt to fill or service a radiator—the bike doesn't have one.

Frequency of Cleaning: Clean the cooling fins and air filter after every 1–2 rides in dusty or muddy conditions. Replace engine oil as specified in your owner's manual for the best results.
