How to Change the Coolant in a 2018 Beta 250 RR: MotoSport Exclusive Guide

Shop parts for a 2018 Beta 250 RR Dirt Bike.

The 2018 Beta 250 RR is a two-stroke off-road machine known for its nimble handling, power delivery, and enduring presence in technical terrain. Regular coolant changes are essential to preserve the bike's engine and cooling system longevity. This proprietary MotoSport guide outlines the robust process for safely swapping the coolant and includes unique tips specific to your Beta.

Step-by-Step Guide: Changing Coolant on Your 2018 Beta 250 RR

  • Preparation
    Ensure the engine is cool before service. Gather the following tools:
    • Allen wrenches
    • Drain pan
    • Funnel
    • Fresh coolant (Beta recommends silicate-free, pre-mixed coolant for optimal protection)
    • Clean rags
    • Gloves
  • Access the Radiators – Drain the Coolant
    Remove the radiator shrouds if necessary to access the radiators. Locate the lower radiator hose – loosen the clamp and disconnect the hose to let coolant drain into your pan. Let the bike rest with the hose off for several minutes to remove residual fluid from hoses & engine passages.
    Tip: If you want a quicker drain, gently tip the bike side-to-side to move liquid from both sides of the radiators.
  • Inspect Components
    While the system is open, inspect hoses for cracks, bulges, or any damage. Inspect the radiator fins for debris or bent areas. Now is the ideal time to upgrade hoses or caps to performance options if desired.
  • Reconnect – Add Fresh Coolant
    Refit the lower hose securely. Pour coolant slowly into the radiator fill neck, letting it settle and bubble through the system. Fill to just above the radiator fins but below the fill neck for ideal level.
    Note: The 2018 Beta 250 RR uses a forced liquid circulation cooling system by pump, and there is no radiator bleeder screw on models newer than 2014. To purge trapped air, rock the bike gently side-to-side and observe bubbles escaping. Top off the coolant as needed.
  • Secure – Final Checks
    Replace and tighten the radiator cap firmly. Reinstall shrouds. Start the engine and let it idle until warm – then shut off and, once cool, check the coolant level again. Refill if necessary. Inspect for leaks.
    The 2018 Beta 250 RR typically requires around 1.0 to 1.3 liters of coolant. Check your owner's manual for exact specifications.
  • Perform Annual Service
    Beta models benefit from annual coolant flushes and system checks. Over time, coolant can lose effectiveness – and internal deposits may build up in the pump or radiators.

Special Notes for 2018 Beta 250 RR Owners

  • Radiator Bleeder Screw: Unlike much older Beta models, the 2018 RR does not have a dedicated bleeder screw. Air removal depends on manual rocking and careful topping off, as described above.
  • Coolant Type: Only use silicate-free, pre-mixed coolant designed for aluminum motocross radiators. Mixing coolants or using automotive products can shorten the lifespan of the Beta's cooling system components.
  • Cooling System Volume: The system capacity is approximately 1.0 - 1.3 liters; slightly less may be present if not all coolant is purged from engine passages.
  • After Maintenance: Ride gently for the first few minutes and periodically check the coolant level, especially after the first heat cycle. Topping off may be necessary as finer air bubbles escape the system.

Regular maintenance of your Beta's cooling system preserves performance and reliability – ensuring you get the most from every ride. For parts, coolant, and upgrades, MotoSport is your one-stop solution.
