This guide includes a full list of necessary tools, detailed steps, and important model-specific considerations to ensure you avoid the most common pitfalls and keep your dirt bike running at its best.
Tools & Supplies Needed
- 8mm T-handle or socket wrench
- Torque wrench (capable of 20 Nm / 14.8 ft-lbs)
- Oil drain pan
- Clean shop rags or towels
- Magnetic drain plug cleaner (optional but ideal)
- New crush washer for drain plug
- Funnel
- KTM recommended transmission oil (0.8 liters)
- Pliers
- Safety gloves (recommended)
- Optional: Oil drip tray device for KTM (to avoid a mess under the skid plate)
Preparation Before You Begin
- Warm up your engine briefly to allow the oil to flow out more freely, but avoid overheating.
- Place the bike on a level surface and use a stand for stability.
- Gather all your tools and supplies–organization is essential for a clean, efficient process.
- If your bike has an aftermarket skid plate, consider removing it or using a special oil chute accessory to direct oil away from the plate for less mess .
Step-by-Step Oil Change Instructions
-
Remove the Oil Fill Cap
- Unscrew the oil fill cap on the right side of the engine. Removing this first allows oil to drain more easily by preventing a vacuum .
-
Position the Drain Pan and Remove the Drain Plug
- Place the oil drain pan directly under the drain plug on the bottom of the engine.
- Using your 8mm T-handle or socket, carefully loosen and remove the drain plug. The oil will begin to drain immediately, so wear gloves and ensure the drain pan is in place .
- Be cautious–oil may be hot if the engine was running.
-
Let the Oil Drain Completely
- Allow several minutes for all oil to drain out. Tilting the bike from side to side gently can help ensure all residual oil escapes.
- If you have a skid plate, you may want to lift or tilt the bike slightly to avoid pooling oil .
-
Clean the Drain Plug and Inspect the Crush Washer
- Use a rag to thoroughly clean the drain plug, especially if it features a magnetic tip. Some metallic debris on the magnet is normal; excessive shavings may indicate an internal issue .
- Replace the crush washer with a new one to prevent oil leaks .
-
Reinstall the Drain Plug
- Install the clean drain plug with the new washer and tighten it by hand at first.
- Use your torque wrench to torque the plug to exactly 20 Nm (14.8 ft-lbs) as specified by KTM . Over-tightening can strip the threads in the aluminum case.
-
Add the New Oil
- Using a funnel, pour in 0.8 liters of KTM-recommended 2-stroke transmission oil through the fill opening .
- Check your owner's manual for KTM's exact oil specification for the 2022 150SX .
MotoSport.com recommends only using brands/grades meeting KTM's specification to ensure proper clutch and gearbox operation.
-
Install and Snug the Oil Fill Cap
- Replace the oil fill cap and use pliers to gently snug it down as KTM recommends, ensuring it is secure and will not vibrate loose during riding .
-
Clean Up and Final Checks
- Wipe away any spilled oil from the engine cases or skid plate.
- Start your engine and let it idle briefly. Check for oil leaks at the drain plug and oil fill cap.
- Shut off the engine, let it settle, then check oil level per the procedure in your 2022 KTM 150SX owner's manual .
Specific Model Call-Outs: 2022 KTM 150SX
- Oil Change Interval: KTM recommends changing transmission oil every 6,000 km (–4,000 miles), but more frequent changes are advised with aggressive riding or racing .
