Step-by-Step Coolant Change Guide
-
Preparation
Make sure the bike is cool to the touch. Put the bike on a level stand in a well-ventilated area. -
Access the Radiators
Remove any shrouds or guards protecting the radiators. Disconnect the radiator cap slowly to relieve pressure. -
Drain the Old Coolant
Place the drain pan beneath the engine. Loosen the lower radiator hose clamp (on the right side) and carefully pull the hose from the radiator to allow old coolant to fully flow out.
Gently rock the bike side-to-side to help drain any residual fluid from both radiators, as the 2022 model no longer uses bleeder screws like older Betas. -
Flush if Needed
For maximum cleanliness, you may rinse the system with distilled water. Reconnect the lower hose securely when finished. -
Refill with Fresh Coolant
Slowly pour new coolant into the radiator or reservoir using a funnel. The correct level is just above the fins of the radiator coredo not overfill. Allow time for coolant to settle and top off as needed. -
Remove Air Pockets
The 2022 Beta 300 RR does not have radiator bleeder screws. After filling, gently move the bike side-to-side or rock it to shift trapped air, helping the coolant settle and distribute evenly. -
Check and Finish
Secure the radiator cap tightly. Reinstall all shrouds or guards. -
Warm Up — Final Top-Off
Start the bike and let it idle for several minutes. Check for leaks and observe the level in the overflow tank after the engine cools. Top off the coolant again if necessary.
Model-Specific Notes for the 2022 Beta 300 RR
- This model uses a pressurized coolant system with no radiator bleeder screw from 2020 onward. Air removal is accomplished by rocking the bike rather than venting manually.
- The recommended coolant capacity is just over 1 liter. Fill to the top of the radiator core fins and do not overfill.
- Always use a coolant rated for aluminum engines to prevent corrosion and maximize performance.
- If operating in hot or technical terrain, consider a cooling fan upgrade and regular inspection of radiator and hoses for debris.
Disposal & Safety Tips

- If coolant is spilled or comes in contact with skin, rinse thoroughly with water.
- Keep coolant out of reach of children & petsit is toxic if swallowed.
