Changing the coolant in your 2019 Beta 250 RR Race is vital to keep the engine running efficiently and prevent overheating. This guide is tailored specifically for the Race Edition 2-strokecovering model-specific steps and tips to help you get the job done right.

What You Need

  • Compatible coolant (pre-mixed, non-silicate recommended)
  • Drain pan
  • 12 mm socket or wrench
  • Flathead screwdriver (for hose clamp)
  • Protective gloves
  • Funnel (optional for refill)
  • Clean rags

Preparation

  • Ensure the engine is cool before startinghot coolant can cause serious burns.
  • Set the bike upright on a stand in a well-ventilated area.
  • Remove the right side panel and radiator shrouds for easy access if needed.

Drain the Old Coolant

  • Locate the radiator cap on the left radiator and slowly remove it to release any pressure in the system.
  • Find the coolant drain bolt at the base of the water pump (right side of the engine). Place a drain pan underneath.
  • Loosen and remove the drain bolt. Allow all coolant to completely drain out. Open the radiator cap if not already done to let it flow freely.
  • If more thorough drainage is needed, you can also disconnect the lowest radiator hose clamp with a flathead screwdriver.
  • Inspect the drained coolant for metal shavings or signs of contamination—replace hoses or gaskets if necessary.

Flush the System (Recommended)

  • Pour distilled water into the radiator, reinstall drain bolt, and briefly run the engine (under a minute) to circulate.
  • Repeat the drain procedure to flush out any remaining debris.

Refill with Fresh Coolant

  • Make sure the drain bolt is reinstalled and torqued securely (do not overtighten).
  • Slowly add the new coolant into the radiator. On the 2019 Beta 250 RR Race, fill it until the level is just above the radiator core fins—do not fill to the very top, as this can cause overflow once the bike heats up (Beta owners have found overfilling leads to the excess being expelled).
  • Gently rock the bike side to side to burp out any trapped air.
  • Install the radiator cap.

Bleed the Cooling System

  • Start the engine and let it idle for several minutes. This circulates coolant and helps any air rise to the top.
  • Shut off the engine, let the bike cool. Recheck coolant level and top off if necessary.
  • Repeat the heat-cycle and cool-down process once or twice until the coolant stays at the correct level and air is fully bled from the system.

Important 2019 Beta 250 RR Race Notes

  • No radiator bleeder screws: Unlike older Betas, this model relies on filling technique/rocking the bike to remove air instead of bleeder bolts.
  • Coolant Capacity: Typical refill is about 1.0–1.2 liters, but always check your level visually.
  • Inspect hoses and caps: The Race Edition works under higher stress, so regularly inspect hoses and the radiator cap seal for wear between coolant services.
  • Use only quality, pre-mixed coolant formulated for aluminum radiators to avoid corrosion and scale buildup.

Post-Service Steps

  • Reinstall all panels and the radiator shroud.
  • Dispose of old coolant responsibly at a hazardous waste centernever dump it down a drain.

Routine maintenance like this helps your Beta 250 RR Race maintain its championship performance and reliability. For all replacement parts, hoses, and recommended coolants, head to MotoSport and get exactly what your bike needs.
