The 2015 Beta 350 RR stands out as a sophisticated machine for riders who demand performance, reliability, and versatility on the trails. Changing the oil is a critical maintenance step, ensuring longevity for this unique Italian dirt bike. Here–s a proprietary MotoSport.com step-by-step guide, including must-know tips specific to your model.
Essential Considerations for the 2015 Beta 350 RR Owner
- Separate transmission & engine oil: Unlike many dirt bikes, the Beta RR features two distinct oil compartments (engine & transmission), each requiring its own drain and refill process.
- No dipstick/check plug accuracy: Rely on measured volume—do not use the check plugs to verify quantity, as excessive drainage may occur and lead to under-filling the compartments.
- Use specified oil: Beta recommends Liqui Moly 10W-50 for best protection and performance, and matching OEM-quality o-rings for each service.
Tools & Supplies Needed
- Drain pan
- 13 mm socket (engine drain bolt)
- 8 mm socket (oil filter cover bolts)
- Torque wrench
- Replacement oil filter
- Replacement o-rings
- Liqui Moly 10W-50 (at least 1.5 liters)
Step-by-Step Oil Change Instructions
- Remove the skid plate for unobstructed access. Place your drain pan underneath the engine.
- Remove both 8mm bolts securing the oil filter cover. Let any residual oil drain out.
- Take out the oil filter and cover o-ring. Leave the cover off for now to maximize drainage.
- Remove the 13 mm engine oil drain bolt. Allow the engine oil to fully drain.
- Remove the transmission oil drain bolt. Let the transmission oil drain completely into your pan.
- Install a new oil filter. Open end toward engine, solid end toward the filter cover.
- Install a new filter cover o-ring. Refit and torque the oil filter cover to 10 Nm.
- Install new o-rings on both drain bolts.
-
Reinstall drain bolts:

Do not use the oil check plug or sight glass (ignore manual suggestion)&emdash;trust the measured volume and keep the check plug sealed for both compartments. - Install fresh o-rings on oil filler caps. Replace and tighten the caps securely.
- Double-check all fasteners & clean any spilled oil. Reinstall the skid plate.
Model-Specific Notes
- The 2015 Beta 350 RR–s oil volumes are not easily verifiable by sight or plug; always measure as outlined above.
- This year/model sometimes featured running changes in filter design and plug torque spec—consult your owner's manual if unsure, but 10 Nm/15 Nm/20 Nm torque (as above) fits most 2015+ RR 4-Strokes.
- Engine and transmission oils must never be mixed—each protects different internal mechanisms and requires full separation.
- Beta recommends changing oil and filter more often than mainstream brands if you ride aggressively or race.
