The 2018 Beta 390 RR Race Edition is a high-performance four-stroke enduro, combining aggressive race geometry, premium suspension, and a distinctive engine character. Regular coolant maintenance is essential to preserve the engine's longevity and performance, especially given this model's advanced liquid-cooling system.
What Makes the 2018 Beta 390 RR Race Edition Unique
- 386cc four-stroke engine with a six-speed gearbox designed for optimal handling and enduro power delivery.
- 48 mm Sachs Closed Cartridge fork with SKF seals and adjustable compression – offering enhanced cooling demands under aggressive riding.
- No kick-start from factory: improved electric starter reliability, so the cooling system efficiency is crucial for consistent start and run reliability under race conditions.
- Lightweight molybdenum steel frame and advanced clutch system, reducing overall weight and heat retention.
Coolant Change Interval and Type
For the best protection, replace coolant every 1-2 years or more frequently if racing or riding in extreme conditions. Use a high-quality ethylene glycol-based, silicate-free motorcycle coolant compatible with aluminum engines and radiators. MotoSport stocks OEM and premium aftermarket coolants formulated for modern Euro dirt bikes.
Required Tools and Supplies
- Motorcycle-specific coolant
- Basic hand tools (ratchets, sockets, Phillips screwdriver)
- Drain pan
- Funnel
- Shop towels
- Safety gloves and eye protection
Step-by-Step Coolant Change Guide
- Place the 390 RR Race Edition on a stable stand. Let the engine cool completely to avoid burn risk.
- Remove the radiator shrouds using the appropriate tools for clear access to the radiator cap and drain bolt.
- Locate the radiator cap – usually on the right top side of the radiators. Slowly unscrew to release system pressure.
- Locate the coolant drain bolt on the lower side of the water pump cover. Position a drain pan underneath and remove the bolt. Allow coolant to fully drain.
- Inspect the coolant for debris or oil. Unusual discoloration could indicate a need for further maintenance.
- Replace and securely tighten the drain bolt.
- Using a funnel, pour in fresh coolant through the radiator cap opening. Fill until near the neck, allowing air bubbles to escape. Squeeze the upper radiator hose gently to purge trapped air.
- Reinstall the radiator cap. Wipe up any spills and reinstall the shrouds.
- Start the engine and let it idle for a few minutes. Watch for leaks and ensure the coolant circulates throughout the system. After the engine is fully warmed, shut it off, let it cool, and recheck the coolant level. Top off if necessary.
Important Model-Specific Notes
- The 2018 390 RR Race Edition has reduced weight and a more compact clutch, which can concentrate heat in the engine compartment. Proper coolant maintenance is vital to prevent localized overheating during aggressive rides.
- Always use coolant compatible with magnesium cases if you opt for advanced engine protection fluids.
- Inspect the radiator fins and hoses for damage whenever the coolant is changed, as robust off-road use can compromise component integrity.
Final Tips
- Never mix different types of coolant unless specified as compatible.
- Safely dispose of old coolant at a proper recycling center—never pour it on the ground.
- If you race or regularly push your Beta 390 RR Race Edition, shorter coolant change intervals can safeguard engine performance and prevent mid-ride overheating.
