Changing the oil in your 2020 Beta 250 RR is a necessary process to keep your two-stroke engine running at its best. This guide provides proprietary step-by-step instructions tailored to your bike, plus key model-specific notes that every owner should know.
What You Need
- Transmission oil – quantity as specified in your manual
- 13 mm socket or T-handle
- Drain pan
- Gloves & shop rags
- Contact cleaner
Steps to Change the Oil
- Warm up the engine briefly to thin the oil for a more complete drain. Shut it off and let it sit for a minute.
- Stabilize your bike upright and level. Place a drain pan beneath the transmission drain bolt, located on the left side low on the engine.
- Remove the oil drain bolt (13 mm) and allow all oil to drain completely. Loosen the oil filler cap to help the oil flow out. Inspect the drain bolt – it's magnetic, so check for and clean off any metal shavings using a rag and contact cleaner.
- Examine the O-ring on the drain bolt. The 2020 Beta 250 RR uses an O-ring seal instead of a crush washer. Replace the O-ring if it's worn or damaged before reinstalling.
- Reinstall and torque the drain bolt to manufacturer spec, ensuring the O-ring sits correctly for a leak-free seal.
- Add the correct amount of transmission oil through the filler cap. Check the exact fill level with your manual or use the bike's sight glass if equipped. Do not overfill – excess oil can lead to clutch or shifting issues.
- Replace the filler cap and wipe up any spilled oil. Double-check the level once the bike is upright and on level ground.
- Let the bike run briefly and recheck the level. Top up if necessary.
- Record your maintenance date and hours – recommended interval is every 8–10 hours of engine use.
2020 Beta 250 RR Model Notes
- This model is a two-stroke with a separate transmission oil bath. Engine lubrication is handled by premix or, where equipped, an oil injection system. Never add two-stroke oil to the transmission oil fill.
- First oil change: It is critical to replace the transmission oil after the first 3 hours of use or following 15 liters of fuel run through the engine, whichever comes first, to remove assembly debris and ensure long-term reliability.
- Always check the O-ring on the drain plug.
If reusing, inspect for nicks or flattening that can cause leaks; replace if needed. - On Race Edition models, you may have an oil injection system. The instructions above are for the standard gearbox/transmission oil. Oil injection system maintenance is separate and not covered in this guide.
- Normal operation: Oil sight glass readings can be misleading if the engine is cold or bike is not level. Always verify level after topping up and running the engine for accurate results.
Pro Tips
- Use a maintenance journal or the hour meter to track oil change intervals.
- Clean up oil drips immediately before reinstalling the skid plate or plastics to avoid attracting dirt and debris.
- Dispose of used oil responsibly at your nearest oil recycling facility.
Your Beta 250 RR will deliver maximum performance and durability when you maintain it with regular oil changes. Handle each job with care and expert parts from MotoSport.
