Tools & Supplies You Will Need

  • O.E.M. or high-quality aluminum-compatible motorcycle coolant
  • Funnel
  • Clean rags
  • Gloves – for handling coolant
  • Drain pan
  • Distilled water (for flushing, optional)
  • Socket set or basic tool kit

Step-by-Step Coolant Change Procedure

  1. Let the bike cool completely. You want the system at room temperature before starting. Never open the radiator cap or drain plug on a hot engine.
  2. Remove the radiator cap slowly to release any lingering pressure.
  3. Locate the drain bolt: On the Beta 300 RR Race, find the coolant drain bolt at the base of the water pump on the engine case. Position your drain pan underneath.
  4. Drain the old coolant. Remove the drain bolt and let the coolant flow into your pan. You may need to gently rock the bike right – this helps move fluid into the right radiator and ensures thorough drainage.
  5. Optional flush: If the system hasn't been serviced in a long time, pour in a 50/50 mix of distilled water and vinegar to flush the system. Replace the drain bolt, briefly run the bike, let cool, and drain once more.
  6. Reinstall the drain bolt. Torque it to manufacturer spec (avoid overtightening).
  7. Fill with fresh coolant. Use a funnel to slowly fill the radiator, stopping periodically to let air escape. Gentle rocking side to side helps dislodge stubborn bubbles in the newer models.
  8. Eliminate remaining air: Start the bike without the radiator cap for about one minute (do not let it idle long) – a few quick throttle blips shake any last bubbles loose. Top off the coolant if needed. Fill the overflow tank to the full line.
  9. Secure the radiator cap.
  10. Final check: After your first ride, recheck coolant levels in both the main radiator and overflow tank.

Model-Specific Tips for 2022 Beta 300 RR Race Owners

  • No bleeder screws: Unlike older Beta models, the 2022 300 RR Race does not use bleeder screws on the radiator. Instead, rocking the bike gently side-to-side is the recommended method for burping air from the system.
  • Coolant choice: Always use a product designed for aluminum engines to protect against corrosion and overheating. Many riders select Motul, Engine Ice, or even high-performance car coolants – just confirm compatibility. Some high-end coolants also improve heat transfer and minimize boiling in slow, technical terrain.
  • Check your fan setup: If you regularly ride technical trails, consider upgrading or installing a radiator fan since the Beta 300 RR Race is known to heat up quickly during slow riding.
  • Thermostat modifications: Some owners remove the thermostat for high-performance/off-road builds. If you do, ensure that the housing is properly shimmed to avoid leaks; otherwise, leave the factory setup intact.
  • Annual service: Changing the coolant annually is recommended – especially if you ride hard, in hot climates, or install accessories such as cooling fans.

Environmental Disposal Notes

  • Always dispose of spent coolant safely at a recycling facility or hazardous waste center. Never pour coolant into drains or on the ground.

Final Advice

  • Double-check all clamps and hoses during your coolant change for leaks or worn parts. Replace anything suspect – and rely on MotoSport for genuine Beta and aftermarket upgrades.
