Tools and Supplies Needed
- Socket wrench set (with appropriate sizes for drain and fill bolts)
- T-handle wrench
- Torque wrench (with metric settings)
- Measuring cup (for precise oil refill)
- Oil catch pan

- Funnel
- Lint-free rags
- Gloves (optional but recommended)
Before You Begin: Model-Specific Call-Outs
- The 2020 KTM 250XCW TPI is a fuel-injected two-stroke and shares its oil change procedure with the KTM 250 EXC TPI, per the official 2020 KTM owner's manual and industry guides.
- Oil capacity for the transmission: 0.8 liters.
- A magnetic drain plug is standard; always inspect for metallic debris, which is normal in small amounts.
- Use the specified crush washer each time to avoid leaks.
- Torque spec for oil drain bolt: Tighten to 20 Nm (14.8 ft-lb) using a torque wrench.
- If your bike is equipped with a skid plate, remove it for easy access to the drain plug.
- Unlike KTM four-strokes, the two-stroke oil change is faster (no oil filter to change).
Step-by-Step Oil Change Instructions
-
Warm up the bike.
Start and let your bike idle for 3–5 minutes. This allows the oil to thin out, so it drains more efficiently.
-
Remove the oil fill cap.
Located on the right-hand engine cover, twist off with your hand. This step helps the oil drain more quickly by preventing a vacuum as it flows out. Set the cap aside in a clean location.
-
Position the catch pan and remove the drain bolt.
Place an oil catch pan under the engine. Use a socket or T-handle to loosen and remove the drain bolt (bottom side of the engine case). Be careful as the oil may be hot. Allow the oil to drain completely.
-
Inspect and clean the magnetic drain plug.
Wipe off any metallic particles from the magnetic tip using a lint-free rag. Minor debris is normal on two-stroke transmissions.
-
Replace the crush washer.
Remove the old crush washer from the drain plug and install a new one. This is crucial to prevent slow leaks over time.
-
Reinstall the drain plug.
Screw the drain plug back into the case by hand first to avoid cross-threading. Then tighten with a T-handle. Finally, use your torque wrench to tighten the drain bolt to 20 Nm (14.8 ft-lb) as specified by KTM.
-
Refill with new oil.
With the drain plug secure, position a funnel in the oil fill opening. Measure out 0.8 liters (or 800 ml) of your preferred two-stroke transmission oil. Slowly pour it in. Using a measuring cup ensures you don't over- or under-fill.
-
Reinstall the oil fill cap.
Screw the cap back down by hand. For added security, use pliers to gently snug it down as KTM recommends (do not overtighten) to prevent it from rattling loose while riding.
-
Check for leaks.
Start your bike and let it idle for 1–2 minutes. Shut it off, then inspect beneath the engine and around the drain/fill area for any oil seeping. A leak often indicates a misaligned crush washer or insufficient bolt torque.
-
Dispose of old oil responsibly.
Pour the used oil from your catch pan into a sealed container and recycle it at an appropriate facility in your area.
Additional Tips for the 2020 KTM 250XCW TPI
- Change oil every 10–15 ride hours for typical enduro use, more often for heavy or muddy conditions.
- Use only fully synthetic, gear-specific oils for best clutch and gearbox performance. Avoid generic car engine oils.
- Keep extra crush washers in your toolbox. Re-using old washers is the number one cause of post-service leaks.
- Carefully wipe down the area around the fill and drain after completing the job; dirt and oil residue can make inspection for future leaks difficult.
Frequently Asked Questions
- What oil should I use?
Officially, 10W-50 fully synthetic transmission oil for KTM two-strokes is recommended; check your owner's manual for approved brands. - Can I change the oil with the bike on its side stand?
Yes, but a bike stand or center stand allows complete drainage. - Do I need to change an oil filter?
No, the 2020 KTM 250XCW TPI does not have an engine oil filter—just change the transmission/gear oil as described.
Changing your oil is one of the most important and easiest ways to keep your 2020 KTM 250XCW TPI delivering top performance on every ride. Follow these steps and tips to ensure your engine and clutch live a long, healthy life. For more tips and the best selection of KTM parts, visit MotoSport.com.
