Keeping your 2018 Beta 390 RR Race Edition in peak condition starts with routine oil changes. Unlike more generic guides, this MotoSport-exclusive walkthrough details specific steps and critical tips unique to the 390 RR Race Edition. Proper oil maintenance ensures maximum engine performance, smooth shifting, and longevity in this Italian thoroughbred of enduro machinery.

What You Need

  • SAE 10W/50 full synthetic oil (0.8 liters recommended)
  • New oil filter
  • Drain pan
  • Socket set and wrench
  • Clean rag and funnel
  • Gloves (recommended)

Before You Start

  • Warm up the engine for 3-5 minutes. This helps the oil drain fully and suspends particulates for removal.
  • Use a stable bike stand to keep your Beta safely upright and level.

Step 1: Remove the Skid Plate (if installed)

Many 390 RR Race Editions are equipped with a factory-fitted or aftermarket skid plate for additional protection. Remove it to access the drain plug more easily. Use the appropriate wrench and be sure to keep track of mounting hardware.

Step 2: Drain the Old Oil

  • Locate the oil drain bolt under the engine. Place the drain pan directly beneath it.
  • Carefully unscrew the drain bolt and let the used oil flow out completely.
  • Once drained, inspect the sealing washer for wear and replace if deformed. A compromised washer can cause leaks.

Step 3: Change the Oil Filter

  • Find the oil filter cover on the right side of the engine.
  • Remove the cover and pull out the old oil filter. Pay attention to the direction and orientation for proper installation of the new filter.
  • Insert the new oil filter and reinstall the cover, tightening it evenly to avoid warping.

Step 4: Reinstall the Drain Plug

  • Once oil is fully drained and the old filter is replaced, screw the oil drain bolt back in and tighten it securelybut avoid overtightening, which can damage the threads in the magnesium engine case.

Step 5: Add Fresh Oil

  • Remove the oil fill cap located on top of the right-side engine case.
  • Pour in 0.8 liters of fresh SAE 10W/50 full synthetic oil (preferred for high-performance four-stroke Betas).
  • Replace the fill cap and wipe any excess oil from the case.

Step 6: Start and Inspect

  • Fire up the engine and let it idle for a minute. This circulates new oil throughout all components.
  • Check around drain plug and oil filter cover for any signs of leaks.
  • Once cool, check the oil level again and top up if needed. The sight glass or dipstick on the right engine cover will display the proper range.

Unique Points of the 2018 Beta 390 RR Race Edition

  • The Racing model features a revised clutch system, improved over previous years for feel and stability. Be aware that clutch engagement may feel more progressive after an oil change–this is by design and optimal for control.
  • A backup kick-starter is not standard—your bike uses a reliable electric starter. Always ensure your battery is in good condition, especially if stalling on remote trails.
  • The quick-access air filter cage makes regular air filter service easy, and is separate from oil maintenance, but it's a good occasion to check both together.
  • Given the engine's performance orientation, always use oil meeting or exceeding Beta's specifications. Poor oil quality can dramatically reduce gearbox and clutch life.

Recommended Oil Change Interval

For aggressive racing or harsh terrain, perform oil changes every 15-20 hours of ride time. For less intensive trail use, 30-hour intervals are reasonable, but more frequent changes preserve the exceptional responsiveness Beta's Race Edition is known for.

Final Tips

  • Dispose of used oil properly—never pour it down drains or on the ground.
  • Keep a maintenance log so you can track oil changes, filter swaps, and engine hours.
  • If you feel notchy shifting or any noise from the engine post-oil change, stop riding and recheck your work.
