Maintaining your 2024 Beta 125 RR keeps it running strong ride after ride. One of the most important maintenance tasks is a regular oil change—this two-stroke model uses transmission oil to keep gears shifting smooth and clutch operation trouble-free. Here is MotoSport's dirt bike-specific guide for proper oil change on your MMY Beta 125 RR. These directions ensure performance, longevity, and reliability.
What You Need
- 720 mL of 10W-50 transmission oil
- 8 mm and 13 mm wrenches
- Catch pan for old oil
- Torque wrench (optional, recommended)
- Clean rags
Steps to Change the Oil
- Warm up the bike for a few minutes. This helps the old oil flow more easily for a complete drain.
- Remove the skid plate by undoing the 8 mm bolts in the front and rear. This exposes the oil drain plug.
- Position your catch pan directly under the drain plug.
- Use your 13 mm wrench to unscrew the drain plug. Let all the old oil flow out. It is smart to tilt the bike upright and let it fully drain.
- Once drained, inspect and clean the drain plug—especially the magnet—which traps metallic debris.
- Reinstall the plug, tightening to manufacturer torque spec if possible. Over-tightening can damage threads—be gentle.
- Remove the filler cap on the engine case.
- Pour in exactly 720 mL of fresh 10W-50 transmission oil.
- Replace the filler cap securely.
Oil Level Check (Alternative Method)
- The bike features a check bolt behind the brake pedal return spring for verifying the oil level. If you did not measure oil volume precisely:
- Keep the bike level and remove the check bolt.
- Oil should just begin to seep from the check hole—this is the correct level.
- Let any excess drain away, then reinstall the check bolt.
Key Notes for the 2024 Beta 125 RR Owner
- This model is a two-stroke—no traditional engine oil circuit. The oil change described here is for the transmission. Regular changes keep shifting crisp and prevent clutch slip.
- Beta recommends 10W-50 transmission oil. Always use high-quality oil suited for wet clutch performance.
- Check oil level regularly. Leaks or loss of oil may cause rapid damage to gears and clutch.
- Inspect the drain plug's magnet each time for excessive metallic debris—it can indicate abnormal transmission wear.
- If riding aggressively or racing, consider changing oil more often than the manual states.
- The MMY 125 RR features straightforward service access—bolts are easily reached and typical change time is under 20 minutes.
Final Tips
- Dispose of used oil responsibly at a proper collection site.
- Take note of the oil's color and debris each change—dark color or excess metal shavings mean it may be time for a deeper inspection.
- Keep a log of every oil change with date and hours.
With correct oil changes, your Beta 125 RR delivers maximum riding fun and minimal downtime. For routine service essentials—filters, seals, gaskets, and the best oils—choose MotoSport for proven quality and fitment you trust for every ride.
