Routine coolant changes are essential for maintaining cooling efficiency and engine longevity on your 2018 Beta 250 RR Race. Here's a proprietary MotoSport guide to performing this crucial maintenance task, plus specific notes owners should know about this model.

What You Need

  • High-quality coolant (silicate-free, premixed for motorcycles)
  • Drain pan
  • Gloves & rags
  • Basic hand tools (socket or Allen wrenches as needed for radiator cap and drain bolt)

Step 1: Preparation

  • Start with a cool engine to avoid burns–never open the radiator cap on a hot bike.
  • Remove the seat and shrouds for easier access to the radiators and cap.

Step 2: Draining Old Coolant

  • Locate the radiator cap (usually left side, on top of the left radiator). Carefully remove it to release pressure.
  • Find the lower coolant drain bolt–typically found at the water pump cover on the right side of the engine. Place a drain pan underneath and remove the bolt. Let all old coolant drain out.
  • If needed, gently rock the bike side to side to encourage more coolant to exit the system.

Step 3: Flushing (Optional But Recommended)

  • For a more thorough job, refill the system with distilled water, reinstall the drain bolt, run the engine briefly, then drain again.
  • Repeat this flush until the drained water runs clear.

Step 4: Refilling with New Coolant

  • Reinstall and tighten the drain bolt to the recommended torque spec.
  • Slowly pour new coolant into the radiator until it fills to just above the core. Allow air bubbles to rise out, gently rocking the bike if needed to help burp pockets from both sides of the dual radiator system.
  • On the 2018 Beta 250 RR Race, you do not have bleeder screws like earlier models–so proper rocking and topping off are especially important to remove trapped air and prevent overheating issues.

Step 5: Bleeding Air and Final Top-Off

  • With the radiator cap still off, start the engine and briefly let it idle. Watch for coolant level drop as air exits–add more coolant as needed to keep the core just covered.
  • Shut the engine off once coolant begins to circulate, top up again to the filler neck, and reinstall the radiator cap.
  • Inspect for leaks and wipe away spills.

Step 6: Heat Cycle and Level Check

  • Once reassembled, let the bike heat up fully until the thermostat opens, then let it cool completely.
  • After cooling, remove the radiator cap and reservoir cap once more to verify and adjust the coolant level–it should reach the base of the filler neck in the radiator.

Special Notes for the 2018 Beta 250 RR Race

  • This bike uses a forced liquid cooling system with a dedicated coolant pump to maintain stable engine temperatures.
    The design helps prevent hot spots and localized overheating during intense riding.
  • Newer Beta models like the 2018 RR Race eliminated radiator bleeder screws. Take extra care with rocking the bike and running the engine to remove air after a coolant change.
  • Factory spec calls for a mixture and quantity that suits high-performance two-stroke operation. Verify you use a compatible, high-quality coolant–avoid automotive coolants containing silicates or phosphates that can harm internal seals and aluminum components.
  • Inspect radiator hoses, the cap, and water pump area for leaks or wear during the process.
  • Beta recommends coolant changes at least annually for racing or high-performance environments, or every two years for light recreational use.

Environmental Safety

  • Always dispose of old coolant safely at a recycling center or hazardous waste location. Never pour coolant down drains or onto the ground.

Proper coolant maintenance ensures your 2018 Beta 250 RR Race runs at its best, even during the most demanding rides. MotoSport is your source for coolant, tools, OEM and aftermarket parts for your bike.
