Changing your coolant is straightforward for DIYers, but a few details unique to this model help ensure the job is done right.
What Makes the 2022 Beta 390 RR Race Edition Unique?
- The engine features titanium intake and steel exhaust valves, requiring consistent cooling to maintain tight tolerances in demanding race conditions.

- Beta's closed-cartridge KYB 48mm fork and machined triple clamps are part of the competition-grade chassis, emphasizing total bike care.
Recommended Tools & Supplies
- High-quality motorcycle coolant or pre-mixed antifreeze (silicate-free, safe for aluminum engines)
- Large drain pan
- Socket set or screwdriver (for radiator shrouds and drain bolt)
- Clean funnel
- Shop towels
- Protective gloves
Step-By-Step Coolant Change for the 2022 Beta 390 RR Race Edition
- Prep the Bike: Ensure the bike is completely cool. Place it securely on a stand with the nose level. Remove the seat and radiator shrouds for easy access to the radiator cap and tanks.
- Drain the Old Coolant: Locate the coolant drain bolt on the lower side of the water pump cover. Position your drain pan. Carefully remove the bolt along with the radiator cap to help the coolant drain completely. Inspect the old coolant for signs of oil or rust – these could indicate other service needs.
- Flush (Optional but Recommended): If the coolant looks contaminated, flush the system by installing the drain bolt and filling with distilled water. Run the engine briefly (without letting it overheat), then drain and repeat until clear water flows out.
- Reinstall the Drain Bolt: Tighten the bolt to factory torque spec. Wipe all spill areas.
- Refill with Fresh Coolant: Slowly pour the new coolant into the radiator using a clean funnel until it reaches the base of the filler neck, keeping the bike level. The system holds about 1.4 liters.
- Bleed the System: To prevent air pockets, gently tilt the bike side to side, then run the engine with the radiator cap off until it reaches operating temp. Watch for air bubbles and top off as the level drops. Once bubbling stops and the coolant level is stable, reinstall the radiator cap securely.
- Clean & Recheck: Reinstall all shrouds and seat. Wipe away any coolant residue to prevent corrosion. After a short ride, recheck the coolant level and top off if needed.
Important Notes for the 390 RR Race Edition Owner
- Only use coolants compatible with modern aluminum engines – avoid automotive coolant containing silicates or phosphates.
- The radiator system is pressurized and can get very hot. Always let the bike cool fully before opening any cap or drain bolt.
- If you consistently lose coolant or see milky discoloration, seek immediate service to avoid major engine damage.
- The Race Edition is designed for spirited riding, so maintenance intervals may be shorter in harsh conditions.
Stay on top of routine coolant service, and your 2022 Beta 390 RR Race Edition will deliver winning performance and enduring reliability on every ride.
