Changing the oil on your 2016 Beta 300 RR Race is a vital part of keeping your two-stroke performing reliablyespecially for this model, which features a simple but robust design tailored for racers and serious trail riders. Follow this proprietary MotoSport guide for a perfect oil change every time, and catch some owner-specific insights to ensure your Beta stays in race-ready condition.
What Makes the 2016 300 RR Race Unique?
- No oil injection – premix is required: The Race Edition uses premix in the fuel rather than oil injection. Ensure you are using high-quality 2-stroke oil (e.g., Motul 800 2T) at the manufacturer-recommended ratio when fueling up, and do not rely on oil injection as you would on other RR or Xtrainer models
- Recommended Transmission Oil: Use a high-quality 10W40 two-stroke transmission oil, such as Motul Transoil Expert 10W40, for best clutch and gearbox performance.
- Oil Capacity (Transmission Side): For a standard change, add 800cc of oil. If performing an engine overhaul, increase this to 850cc.
Essential Tools & Supplies
- 8mm socket or T-handle (for skid plate removal, if equipped)
- Drain pan
- Measuring cup for oil
- New transmission oil (see above)
- Contact cleaner & clean rags
Step-by-Step Guide
- Warm up the engine: Run the bike for a few minutes to warm the oilthis helps it drain thoroughly.
- Stabilize the bike: Stand the Beta upright and level on a center stand or suitable lift.
- Remove the skid plate (optional): If installed, remove the skid plate using an 8mm driver so you can access the drain bolt more easily and clean debris trapped under the engine.
- Locate and remove the drain bolt: Place a drain pan under the transmission drain bolt (bottom of the right side case). Remove the bolt and let oil drain completely.
- Clean and inspect: Wipe any debris from the area and inspect the drain plug’s O-ring for wear. Replace if needed.
- Reinstall the drain bolt: Torque to the manufacturer’s spec (usually around 10 Nm or 7.5 ft-lbs for Beta models, but consult your service manual to confirm).
- Measure and add new oil: Using a graduated cup, measure exactly 800cc of transmission oil and pour it into the transmission fill port. If you’ve performed engine work, add 850cc instead.
- Check oil level: Bring the bike upright and level, remove the oil check bolt, and verify oil is at the ideal level. If necessary, drain excess or add more until it is correct.
- Reinstall all bolts and clean up: Replace the check bolt, then the fill cap. Clean off any spilled oil with contact cleaner and wipe down the case. Reinstall the skid plate if used.
Additional Notes for 2016 Beta 300 RR Race Owners
- Always use a high-quality premix at the specified ratio for engine lubrication—never run straight gasoline in this model.
- Stay vigilant about oil changes, especially after wet or muddy rides, as gear oil contamination can accelerate clutch wear.
- If your transmission shifts poorly or you notice clutch drag, check oil level and replace oil more frequently.
