Changing the coolant in your 2025 Beta 250 RR Race is a straightforward maintenance task that keeps your engine running at optimal temperature and prolongs its life. This guide details every step, along with essential model-specific notes to ensure your Beta remains race-ready.

What You Need

  • Coolant (pre-mixed for motorcycles, ethylene glycol based as recommended)
  • Drain pan
  • Socket set and screwdriver
  • Funnel
  • Gloves and rags for cleanup

Before You Start: Model-Specific Notes

  • Coolant Capacity: The 2025 Beta 250 RR Race has a coolant circuit volume of approximately 1300 ml. Ensure you prepare enough coolant to completely refill the system†.
  • Cooling System: This model uses forced liquid circulation via a pump, providing consistent engine cooling under extreme use.
  • Coolant Overflow Reservoir: New for 2025, these bikes include a coolant overflow reservoir, which helps prevent overheating during prolonged or extreme riding†.
  • Radiator Cap: Use only the OEM radiator cap to maintain system pressure and avoid leaks.

† Per 2023+ RR Race model specs; confirm capacity in the service manual for the latest 2025 model details.

Step-by-Step Coolant Change Procedure

  1. Prepare the Bike
    Ensure your Beta is completely cool; never open the radiator cap when hot as pressurized steam or hot coolant can cause burns. Place the bike upright on a stand for access.
  2. Access the Radiator
    Remove the seat and side shrouds using your socket set. Locate the radiator cap on the left side of the bike.
  3. Drain the Old Coolant
    Place a drain pan beneath the water pump area. Find the coolant drain bolt – typically on the lower side of the water pump cover. Slowly loosen the bolt and allow all coolant to drain. Remove the radiator cap to speed draining.
  4. Inspect and Clean
    Check hoses, the drain bolt washer, and radiator for debris or corrosion. Flush the system with distilled water if the coolant appears dirty; repeat until the draining water is clear. Reinstall and tighten the drain bolt to the specified torque.
  5. Refill with Coolant
    Insert a funnel into the radiator neck. Pour fresh coolant until it reaches the bottom of the neck. Fill the overflow reservoir to the marked line as well.
  6. Burp the System
    Gently rock the bike side-to-side and compress radiator hoses to remove trapped air. Top off if necessary, ensuring proper level.
  7. Reassemble and Run the Engine
    Replace the radiator cap, reinstall shrouds and seat. Start the engine and let it idle until the cooling fan cycles once or the engine warms up. Turn off the bike, let it cool, and check coolant level; add as needed.

Things to Know About the 2025 Beta 250 RR Race

  • Thanks to its updated frame and improved cooling efficiency, the 2025 model is better equipped for tough enduro terrain and sustained high RPMs.
  • The new overflow reservoir protects against sudden spikes in engine temperature during grueling rides.
  • OEM coolant is recommended for maximum corrosion protection and compatibility with the Beta's alloy components.
  • Always check for leaks after a coolant change, especially around the drain bolt and hose connections.

Pro Tips

  • Change your coolant at least once per year, or after any major overheat incident.
  • Dispose of used coolant safely; it's toxic to animals and the environment. Most auto parts stores accept old coolant for recycling.
