Changing the oil in your 2011 KTM 350XCF is one of the most critical maintenance tasks to ensure longevity and performance. This step-by-step guide covers all the tools you'll need, detailed instructions, and specific notes unique to the 350XCF, making it easy for both first-time and seasoned riders.
Tools & Materials Needed
- 13mm wrench (for drain plug)
- 8mm wrench or socket
- Oil filter (OEM recommended)
- Fresh engine oil (KTM recommends Motorex Cross Power 4T 10W-50)
- Drain pan for used oil
- Funnel for pouring new oil
- Rags for cleanup
- Torque wrench (preferably capable of low settings, ~7.5 Nm for filter)
- Contact cleaner (optional, to clean up spills)
- Replacement O-rings for drain plug and oil filter cap (strongly recommended each change)
- Gloves (optional, for cleanliness)
Preparation
- Start by running the engine for a few minutes to warm up the oil. Warm oil flows better and drains more completely.
- Turn off the bike and place it on a secure stand. Make sure the engine is cool enough to touch comfortably.
Step-by-Step Oil Change Instructions
-
Remove the Skid Plate (if installed):
The 2011 KTM 350XCF uses a skid plate secured by a quick-release pin or bolts. Turn the pin or unbolt, then carefully remove the plate to access the drain plug and oil screens beneath the engine.
KTM makes this step easy compared to some brands—no special tools required. -
Locate and Remove the Drain Plug:
With the bike upright, find the 13mm drain plug at the bottom left side of the engine case. Place your drain pan underneath and slowly unscrew it, applying gentle inward pressure as you remove it to prevent it from dropping into the pan.
Be aware: used oil will likely be hot. Allow it to drain completely before proceeding. -
Remove Oil Filter and Oil Screens:
The 350XCF uses an external oil filter and two oil screens. Remove the filter cover (typically secured with an 8mm bolt or Allen head). You can remove the main oil screen next to the drain plug as well. Clean both screens thoroughly with contact cleaner and inspect for metal debris–a sign of abnormal engine wear.
Replace the oil filter with a new OEM or high-quality filter. -
Check and Replace O-rings:
Inspect the O-rings on the filter cover and drain plug for nicks or wear. Replace if needed to prevent leaks. -
Reinstall Screens, Filter, and Drain Plug:
Reinstall both cleaned screens, the new filter, and the drain plug. Always start the threads by hand to avoid cross-threading. Torque the oil filter cover to approximately 7.4 Nm (5.5 ft-lbs); do not overtighten. -
Add New Oil:
Remove the oil fill cap (on the right side). Using a funnel, add 1.1 liters of oil. KTM specifies this capacity for the 350XCF engine.
For best results, some recommend filling the new filter housing a third full before inserting the filter, as stated in the manual. -
Check Oil Level:
Use the sight glass (on the lower engine case, right side) to check oil level. It should be between the mid and top markers. If the rear brake pedal blocks your view, press it down slightly. Top off as needed until level is correct.
Double-check for leaks around the drain plug and the filter cover. -
Prime the Oil System:
Before starting, "prime" the system by holding down the engine stop switch and turning the starter for a few seconds (no spark). This circulates oil without load.
Start the engine, run for 30-60 seconds, then shut off and re-check the oil level. Top off if necessary. -
Final Steps:
Reinstall the skid plate. Use contact cleaner and rags to remove any spilled oil from the engine, frame, or floor. Dispose of your used oil and filter responsibly, as required by local regulations.

- Oil Capacity: 1.1 liters is specific to the 2011 KTM 350XCF. Always double-check the manual for your model and year if unsure.
- Torque Settings: The oil filter cover and drain plug require very low torque (7.4 Nm/5.5 ft-lbs). Do not overtighten—threaded cases are soft aluminum and easily stripped.

- Oil Type: KTM recommends Motorex Cross Power 4T 10W-50. Using high-quality synthetic oil is key for performance-oriented motors like the 350XCF.
- Inspection: Metal shavings in the screens or filter can signal bigger problems—consult a pro if you see significant metal in your used oil.
