How to Change the Coolant in a 2020 Beta 350 RR Race Edition

Shop parts for a 2020 Beta 350 RR Race Edition Dirt Bike.

Maintaining peak performance for your 2020 Beta 350 RR Race Edition means regular coolant changes—a crucial job for engine longevity and optimal cooling. Follow this proprietary MotoSport guide for a reliable coolant swap tailored specifically to your bike.

Preparation – What You'll Need

  • Quality dirt bike coolant (engine ice or Beta OEM-recommended fluids work well)
  • Ratchet and sockets
  • Drain pan
  • Funnel
  • Clean rags
  • Protective gloves and eyewear

Step 1: Ensure Engine Cool

Allow your Beta 350 RR Race Edition to fully cool. Draining hot coolant risks burns and can damage engine components. Coolant replacement should always be performed with the bike upright and level.

Step 2: Access the Radiator

  • Remove the seat and side panels if necessary for access.
  • Locate the radiator cap on the right side – carefully unscrew the cap.

Step 3: Draining the Coolant

  • Position a drain pan under the engine.
  • Locate the coolant drain bolt at the water pump area.
  • Unscrew the drain bolt, let coolant flow into the pan. Replace the bolt after draining.
  • No bleeder screw is used on 2020+ models; simply rocking the bike gently can help clear residual coolant from the system.

Step 4: Inspect System

  • Check hoses and clamps for wear or leaks—replace if needed for added reliability.
  • Inspect radiator for bent fins or debris and clean if necessary.

Step 5: Filling with Fresh Coolant

  • Using a funnel, pour new coolant into the radiator opening. The system capacity is 1.3 liters.
  • Do not overfill—fill until coolant is just above the radiator fins but below the neck. This prevents pressure problems and overflow when the engine heats up.

Step 6: Purge Air from the System

  • Replace the radiator cap securely.
  • Start the engine and let it run for 5–10 minutes to circulate the coolant and purge air.
  • Stop engine, allow it to cool, then recheck coolant level. Top up as needed so level remains above fins without reaching the neck.

Step 7: Final Checks

  • Wipe away any coolant off the engine and frame.
  • Reinstall any removed plastics or panels.
  • Inspect for leaks after the first ride.

Model-Specific Notes for Your 2020 Beta 350 RR Race Edition

  • The 350 RR Race Edition features a forced liquid cooling system and does not use radiator bleeder screws found on older Betas—purging air is done simply by cycling the coolant through gentle running after refill.
  • Beta recommends maintaining correct coolant circuit levels (1.3 liters) for optimal performance. Check the level regularly, particularly after intense riding.
  • The stock cooling fan is activated by an integrated sensor on 4-stroke Race Editions, so no external brass sensor installation is necessary.

Tips for Best Results

  • Change coolant annually for best protection.
  • Use high-performance coolants for extreme conditions.
  • Monitor for coolant loss after hard rides or extreme heat.

Following this MotoSport guide ensures your Beta 350 RR Race Edition stays cool and ready for peak off-road action—bring confidence to every ride with proper maintenance done right.
