What You’ll Need
- Fresh transmission oil (690cc for this model)
- Drain pan
- 13mm socket for the drain bolt
- Funnel
- Clean rags
- New O-ring for the drain bolt if needed
- Contact cleaner (optional for cleaning surfaces)
- Skid plate tools (if equipped)
Step-by-Step Oil Change Guide
-
Warm the Engine
Start and run the bike for several minutes. Warm oil drains faster and helps carry out contaminants.
Tip: Keep the bike upright using a stand. -
Remove the Skid Plate (if equipped)
Use the appropriate tool to unbolt the skid plate for clear access to the drain bolt. -
Clean Around the Drain Plug
Wipe any dirt away from the area around the plug. This helps keep debris out of your engine. -
Drain the Old Oil
Place your drain pan underneath. Using a 13 mm socket, remove the drain plug, then allow all oil to drain.
Inspect the oil for metallic particles or debris. -
Check & Clean the Drain Plug and O-ring
Inspect the plug’s O-ring for cracks or wear. Replace if damaged. Wipe the plug clean before reinstalling. -
Reinstall the Drain Plug
Once drained, thread in the drain plug by hand and then torque it to spec (see your owner’s manual for specifics). -
Refill with Oil
Locate the oil fill cap on the right engine cover. Remove it and use a funnel to pour in 690cc of new transmission oil.
Noteworthy: Overfilling can cause clutch issues; underfilling risks engine damage. Always measure precisely. -
Check Your Work
Wipe down any spilled oil. Reinstall the skid plate if necessary. Start the engine and check for leaks.
Model-Specific Tips for the 2019 Beta 125 RR
- The 2019 125 RR is a 2-stroke – oil goes in the transmission, not mixed with fuel. Use only oil formulated for 2-stroke transmissions.
- Factory oil change intervals are every 10 hours or after harsh riding sessions.
- This bike takes exactly 690cc of transmission oil unless the engine has been rebuilt, in which case more may be needed.
- The drain plug’s O-ring is critical for proper sealing. Always inspect and replace if necessary.
- Some bikes use dipsticks; others a sight window. Check your specific machine and reference your manual for the most precise measurement.
Why Oil Changes Matter for Your Beta 125 RR
2-stroke dirt bikes like your 125 RR operate at higher RPMs and their transmissions work hard. Fresh oil ensures smooth clutch function, reliable shifting, and internal protection from heat & contaminants.
