Proper coolant maintenance for your 2020 Beta 390 RR Race Edition is essential to ensure optimal engine performance and longevity. The 390 RR Race Edition features a newly redesigned water pump and simplified hose layout, improving cooling efficiency and making coolant changes straightforward for most home mechanics–2. Below is MotoSport's proprietary step-by-step guide for changing the coolant, along with specific notes for this race-focused model.
Preparation
- Make sure the bike is completely cool before starting. The cooling system operates under pressure when hot, and releasing the radiator cap prematurely can result in burns.
- Position the bike upright or on a stand for best access.
- Gather these items: a drain pan, fresh coolant compatible with aluminum components, a funnel, basic hand tools (8mm and 10mm sockets or wrenches), and safety gloves.
Step–by–Step Coolant Change Process
-
Remove the radiator cap.
Locate the radiator cap near the handlebars. Remove it slowly to allow any residual pressure to vent. -
Locate and remove the coolant drain bolt.
On the 390 RR Race Edition, the drain bolt is generally found at the bottom of the water pump housing—part of the newly updated cooling system. Use your socket or wrench to loosen it. Place the drain pan beneath to catch old coolant. -
Inspect coolant and system.
Examine the drained coolant for debris, oil slicks, or metal particles, which can indicate deeper engine issues. The 2020 Race Edition benefits from a redesigned oil and cooling circuit to keep temperatures lower and reduce wear–2. -
Flush if needed.
If the coolant appears particularly dirty or you suspect contamination, flush the system with distilled water. Reinstall the drain bolt, fill with distilled water, run the bike briefly, and repeat the draining process. -
Replace drain bolt and tighten.
Ensure the sealing washer is intact before reinstalling. Torque to manufacturer spec. -
Add fresh coolant.
Using a funnel, slowly add new coolant directly to the radiator. The simplified hose design on the 2020 model improves filling flow and reduces air pockets–2. Fill to the bottom of the filler neck. -
Bleed the cooling system.
Tilt the bike side–to–side and gently squeeze radiator hoses to release trapped air. With the cap still off, start the engine and let it run momentarily. Recheck coolant level and top off if necessary. -
Reinstall radiator cap.
Ensure a tight fit to maintain system pressure. -
Clean up and check for leaks.
Wipe away any spilled coolant and inspect around the water pump and hoses for drips.
Key Features & Considerations for the 390 RR Race Edition
- Redesigned cooling circuit: 2020 models have improved flow-rate and heat transfer, helping performance on tougher terrain and aggressive riding sessions–2.
- Magnesium covers: Clutch and flywheel covers are magnesium, making coolant choice especially important—avoid silicate-heavy coolants that can attack magnesium alloys–2.
- Simplified hose routing: Newer layout makes maintenance easier and helps prevent air pockets during refills.
- Tool-less access: Push-button seat and easy air filter access so you can combine regular maintenance tasks efficiently–3.
- Battery system: Improved charging system provides reliability for electric start, so always check for water pump leaks during electrical component inspections–4.
Tips for Race Edition Owners
- Inspect hoses and connections regularly—the bike is optimized for racing, so wear and tear occurs faster than street-focused motorcycles.
- Always use coolant formulated for aluminum and magnesium, and replace annually or per race season.
Changing your coolant not only protects your engine but preserves the handling and power advantages of the 2020 Beta 390 RR Race Edition. Rely on MotoSport for all your maintenance needs—and keep your machine running at peak performance.
