Shop parts for a 2014 Beta 350 RR Dirt Bike!
The 2014 Beta 350 RR stands out among enduro machines for its Italian craftsmanship and distinct two-oil system. Performing regular oil changes is crucial not only for optimal engine life but also for keeping your Beta's uniquely smooth power delivery. This step-by-step MotoSport guide outlines the entire oil change procedure and highlights special tips every 350 RR owner should know.
What You Need
- 13 mm socket
- Drain pan
- New oil filters (engine & transmission)
- New O-rings for drain bolts and filter cover
- Torque wrench (measures in Nm)
- High-quality 10W-50 four-stroke oil
- Rags and gloves
Unique Model Notes for the 2014 Beta 350 RR
- This model uses separate engine and transmission oil circuits. Both sides need to be serviced each time.
- The recommended oil fill for each side is 750 ml (milliliters). The factory recommends 10W-50 full synthetic 4-stroke oil.
- The sight glass lets you check engine oil while the engine is running – a quirk unique to Beta four-strokes. For the transmission side, use the check bolt to verify level (oil should just reach the bottom threads).
- If you own a rare "Race Edition" 2014.5, confirm oil specs separately as they may differ from standard models.
Step-by-Step Oil Change Instructions
- Warm up the engine. Run the bike for 2-3 minutes to help the oil flow out smoothly. Shut it off and let it cool just enough for safe handling.
- Remove skid plate (if equipped) to access the drain bolts.
- Drain the engine oil.
- Place a drain pan under the engine drain bolt (13 mm).
- Remove the drain bolt and allow the oil to completely drain out.
- Remove the engine oil filler cap to ease flow.
- Drain the transmission oil.
- Locate and remove the transmission drain bolt. Let the oil drain fully.
- Remove and replace the filters.
- Remove both 8 mm oil filter cover bolts. Carefully withdraw the old filter and O-ring; replace them with new.
- Install the new filter with its open end facing the engine and the solid end to the cover.
- Swap O-rings & reinstall drain bolts.
- Fit new O-rings on both drain bolts.
- Torque the engine drain bolt to 15 Nm and the transmission drain bolt to 20 Nm.
- Refill with fresh oil.
- Pour 750 ml of oil into each side – engine and transmission.
- Replace oil filler cap O-rings and tighten caps securely.
- Verify oil level.
- For engine: Start the bike, let it idle two minutes, then observe the oil sight glass while the bike is upright. Oil should reach around the middle of the glass.
- For transmission: Remove the check bolt – oil should just barely begin to weep through the bottom of the threads.
Important Tips for 2014 350 RR Owners
- Beta's oil sight glass will read differently before and after rides. Variation is normal – only check engine oil while running.
- Proper torque is critical; overtightening can strip threads on soft aluminum cases.
- Always use motorcycle-specific oil and new filters for each change to ensure longevity of both the engine and the unique transmission system.
- Consider keeping extra O-rings and filters in your garage or race kit, as Beta's dual circuit oiling system means more frequent servicing than most competitors.
Your 2014 Beta 350 RR rewards routine oil changes with legendary reliability and that classic Beta feel – smooth, tractable power through any terrain. Stay ahead with genuine parts and expert support from MotoSport.
