The 2017 Beta 250 RR is a 2-stroke enduro favorite–light, agile, and purpose-built for conquering trails. Maintaining your transmission oil is crucial for performance and longevity. This proprietary MotoSport oil change guide highlights model-specific notes and proven tips to get the job done right.

Tools & Supplies Needed

  • 13mm socket (preferably T-handle for ease)
  • Drain pan
  • Contact cleaner & clean rags
  • Funnel
  • Beta-approved transmission oil (800cc)
  • Gloves

Step 1: Warm Up & Prep the Bike

Start the engine and let it idle for several minutes. This thins the transmission oil for a more complete drain. Place the bike on a stand so it remains upright and level.

Step 2: Remove the Skid Plate (if installed)

If your bike has a skid plate, remove it for direct access to the drain bolt beneath the engine case.

Step 3: Drain the Oil

  • Wearing gloves, use the 13mm socket to remove the transmission drain bolt located beneath the right side of the engine case.
  • Angle the drain pan under the bolt and allow all the oil to drain completely.
  • Loosen the oil fill cap on top of the stator cover to allow air in and ensure smooth flow.

Step 4: Inspect & Clean the Drain Plug

  • The Beta 250 RR drain plug has a built-in magnet. Inspect for metal debris–minor flecks are normal, but watch for significant shavings.
  • Clean the plug with contact cleaner and a rag.
  • This plug uses an O-ring, not a crush washer. Inspect the O-ring carefully; replace if damaged or flattened to ensure proper sealing.

Step 5: Reinstall the Drain Plug

  • Thread the drain plug back in by hand to avoid cross-threading, then torque snugly (do not over-tighten). Clean any oil residue around the case area.

Step 6: Refill with Fresh Oil

  • Check your manual or Beta specifications: The 2017 Beta 250 RR uses 800cc of transmission oil for a standard oil change.
  • Pour the oil slowly into the filler hole using a clean funnel.
  • Wait a minute for the oil to settle. Confirm level using the check bolt if your model has one, or refer to the sight glass. If you overfill, allow excess oil to drain from the check bolt until level.

Step 7: Secure the Filler Cap

  • Inspect the O-ring on the filler cap for any dirt or damage. Clean and reinstall the cap securely.

Step 8: Final Check & Maintenance Log

  • Wipe off any spilled oil and reinstall the skid plate if present.
  • Start the engine–check for leaks around both the drain plug and filler cap.
  • Make a log entry of your oil change date and engine hours. Beta recommends changing transmission oil every 8–10 hours for optimal clutch protection, especially in harsh or wet riding conditions.

Owner Notes: The 2017 Beta 250 RR Difference

  • No engine oil change required–only transmission/clutch oil! This is a 2-stroke with a separate premix system, so you are only performing a gearbox oil service.
  • O-ring on drain/fill bolts: Uncommon for some brands, so inspect these for leaks or wear at every service.
  • Magnetic drain plug: Designed to trap metal particles and prolong transmission life. Keep it clean and regularly inspected.
  • Capacity tip: Beta's 800cc spec ensures smooth clutch operation. Do not overfill, as excess oil may cause clutch drag or leaks.

Regular transmission oil changes ensure your 2017 Beta 250 RR continues to deliver its responsive feel and unbeatable trail performance. Trust MotoSport for the right parts, tools, and factory-approved oils that keep your ride in peak condition.
