Maintaining your 2018 Beta 500 RR-S is key to its riding performance – and oil changes are a critical part of that. The 500 RR-S is unique for its separate engine and transmission oil systems, each requiring its own oil change procedure. Here is your exclusive MotoSport step-by-step guide.

Essential Tools & Supplies

  • 13mm socket & ratchet
  • 8mm socket (for oil filter cover & skid plate)
  • Drain pan
  • Replacement oil filters (engine)
  • Replacement o-rings for filter cover, drain bolts, and filler caps
  • Liqui Moly 10W-50 Synthetic Oil – 750ml for engine, 750ml for transmission (minimum Beta spec)
  • Torque wrench (capable of 10 Nm, 15 Nm, 20 Nm)
  • Clean rags

Oil Change Procedure (Engine & Transmission)

  1. Warm up the bike for 2-3 minutes to ensure oil flows easily, then turn off and let it cool just enough to handle safely.
  2. Remove the skid plate using 8mm bolts to access drain and filter areas.
  3. Engine oil:
    • Place drain pan below the engine drain bolt (front left, slightly larger, contains a pre-screen).
    • Using a 13mm socket, remove the engine oil drain bolt. Allow oil to drain thoroughly.
    • Remove the two 8mm bolts on the oil filter cover. Carefully remove the cover, oil filter, and its o-ring.
  4. Transmission oil:
    • Locate the transmission drain bolt on opposite side (also 13mm socket).
    • Remove the transmission drain bolt and allow full drainage.
  5. Replace o-rings on both drain bolts, filter cover, and filler caps to prevent leaks.
  6. Install new oil filter: The open ends should face the engine, solid to the cover. Fit new o-ring and cap. Torque filter cover bolts to 10 Nm.
  7. Reinstall drain bolts:
    • Torque engine drain bolt to 15 Nm.
    • Torque transmission drain bolt to 20 Nm.
  8. Fill oil:
    • Add 750 ml Liqui Moly 10W-50 to the engine side.
    • Add 750 ml Liqui Moly 10W-50 to transmission side.
    • Replace o-rings on oil filler caps, install & tighten securely.
  9. Check oil level:
    • Run engine for 2 minutes, then check sight glass. Oil should settle within red circle.
    • Do NOT overfill – Beta's system is sensitive to oil levels.
  10. Reinstall skid plate.

2018 Beta 500 RR-S Owner Notes

  • This model has separate engine & transmission oil cavities. Both must be serviced independently with the full recommended oil volume.
  • No dipstick: rely on the sight glass for engine oil – transmission fill has no visual check, so precise measurement (750 ml) is crucial. Overfilling affects performance.
  • Beta recommends fresh o-rings each change – reusing can cause leaks due to deformation.
  • Always use the specified oil weight – 10W-50 premium synthetic – for proper clutch and gearbox lubrication.
  • This model's filter orientation is important; improper fitment reduces flow and protection.

Final Checks & Tips

  • Start the bike after filling. Let idle for 2-3 minutes. Check for leaks.
  • Re-confirm oil height in sight glass with bike vertical on level ground.
  • Dispose of used oil properly – follow local environmental guidelines.

Performing regular oil changes keeps your Beta's engine and transmission performing at their peak – and ensures smooth rides wherever the trail takes you.
