Regular coolant changes on your 2017 Beta 350 RR Race Edition are critical for optimal cooling system performance and engine longevity. Below is a robust, step-by-step MotoSport guide, including key model-specific insights to help keep your high-performance Beta reliable both on and off the trail.

Preparation and Safety

  • Make sure the motorcycle is upright and on a flat surface.
  • Allow the engine to fully cool before loosening any radiator or drain caps to avoid injury from hot coolant or steam.
  • Wear appropriate gloves and protective clothing to avoid contact with coolant.

Required Tools and Materials

  • Socket set or screwdrivers (to remove engine casing and drain screws)
  • Catch pan suitable for coolant disposal
  • Fresh coolant (see your owner manual for recommended types–never use a non-approved coolant)
  • Torque wrench (to ensure proper reinstallation torque where specified, typically 10Nm on engine protection plate screws)
  • Shop rags for cleaning

Draining the Old Coolant

  1. Remove the engine protection plate by loosening the mounting screws.
  2. Place a catch pan under the crankcase coolant drain bolt (often located on the lower side of the engine cover).
  3. Carefully unscrew the radiator cap to release any residual pressure.
  4. Remove the coolant drain bolt and any other specified drain screws; allow coolant to fully drain into the catch pan.
  5. Inspect the old coolant for signs of contamination or oil–milky appearance may indicate internal gasket issues.

Flushing (If Needed)

If the coolant is especially dirty or you wish to perform a more comprehensive maintenance, flush the system with distilled water. Pour distilled water through the radiator, allow it to drain, and repeat until water runs clear. The Beta cooling system is simple and typically drains completely with gravity, though a flush can help with heavy contamination.

Refilling with Fresh Coolant

  1. Re-install all drain screws and torque to the specification found in your manual (typically 10Nm for this model's protection plate screws).
  2. Slowly fill the radiator through the filler neck. On the 2017 Beta 350 RR Race, fill up to just above the radiator core fins–do not fill all the way to the filler neck to avoid overflow as the engine heats up. An inch below the neck is recommended.
  3. Reinstall the radiator cap.
  4. Start the engine and let it idle for several minutes. Watch for leaks or drips.
  5. Allow the engine to reach normal operating temperature; this helps purge air from the system.
  6. Shut the engine off, let it cool completely, and re-check the coolant level. Top off as needed, again only to just above the fins.

Post-Service Checks

  • Check for leaks around all drain and filler points after your first ride.
  • Inspect the coolant level regularly as air may continue to work itself out of the system in the next couple heat cycles.

2017 Beta 350 RR Race Edition Model Reminders

  • Always use the coolant type and specification recommended by Beta. Using the wrong coolant can cause corrosion or damage.
  • This model's radiator is built for high output, liquid-cooled performance–don’t shortchange the cooling system by overfilling or using non-premium fluids.
  • Coolant capacity can vary based on how thoroughly the system is drained, but plan for approximately 1.3 liters for a full change. Don’t exceed the recommended top-off level.
  • Your Beta does not have special air bleed screws; filling carefully and running the engine should be enough to eliminate trapped air. Double-check level after a complete cooling cycle.

Disposal and Environmental Note

Coolant is toxic–never dump used coolant on the ground or down household drains. Take all used coolant to a certified recycling or hazardous waste facility.
