Performing a routine oil change is one of the best ways to keep your KTM 690 Enduro R (2011) running strong and reliable. Follow this detailed, step-by-step guide from MotoSport.com to keep your bike in top condition. This process covers all necessary tools, critical model-specific notes, and each step needed, from preparation to final checks.

Tools & Supplies Needed

• 10W-50 fully synthetic motorcycle oil (meets JASO MA/MA2 specifications)
• New oil filter (OEM recommended for best results)
• Replacement O-rings and crush washers
• Oil catch pan
• Socket wrench set (with 8mm, 13mm sockets or as specified)
• Torque wrench
• Torx bits (as required for filter covers/skid plate)
• Flathead screwdriver or pick (for removing oil screens)
• Clean rags or paper towels
• Funnel
• Gloves (optional but recommended for cleanliness)

Preparation

• Warm up the bike for several minutes to allow the oil to thin out, ensuring more complete drainage.
• Ensure the motorcycle is on a level surface and supported securely, ideally on a center stand or paddock stand.

Step-by-Step Oil Change Instructions

1. Remove the skid plate (if installed)
   
   • Locate and remove the two front bolts holding the skid plate. The plate should then slide off easily.
   • This is necessary to access the oil drain plug and oil screens.
2. Drain the old oil
   
   • Find the main oil drain plug located under the engine.
   • Place the oil catch pan beneath the drain plug and use a socket wrench to remove the plug.
   • Allow all oil to drain completely. Inspect and, if necessary, replace the crush washer on the plug.
3. Remove and clean the oil screens
   
   • The 2011 KTM 690 Enduro features two oil screens for best filtration.
   • Locate the oil screens (one on the right, one towards the front/lower area of the engine).
   • Use the correct socket or Torx bit to unscrew each screen’s cover. Gently remove the screens using a small flathead screwdriver or pick.
   • Clean screens thoroughly with brake cleaner or solvent, inspecting for any metal particles or debris which may indicate engine wear.
   • Inspect and replace O-rings if they are tough, cracked, or deformed.
4. Remove and replace the oil filters
   
   • Your bike uses two separate oil filters (one short, one long). Always replace both during each oil change to ensure maximum protection.
   • Locate each oil filter cover on the right side of the engine.
   • Remove the covers with a socket or T-handle. Take out the old filters using needlenose pliers if needed.
   • Lubricate new filter O-rings with a bit of fresh oil before installing.
   • Install new filters, ensuring correct orientation (long and short go in specific locations–double-check your service manual if unsure).
   • Reinstall the filter covers. Tighten to 4.4 ft-lb (6 Nm) as per the 2011 KTM 690 Enduro spec to prevent leaks or damage.
5. Reinstall oil screens and drain plug
   
   • Insert the cleaned (or new) screens back in place, ensuring correct fitment.
   • Tighten covers to manufacturer specifications.
   • Replace and hand-tighten the oil drain plug. Tighten to 15 ft-lb (20 Nm).
6. Add fresh oil
   
   • Double-check that all covers and plugs are torqued correctly.
   • Using a funnel, pour in 1.7 liters of 10W-50 fully synthetic oil.
   • Let the oil settle for a minute, and check the sight glass for proper fill between the minimum and maximum lines (located on the engine case).
7. Run and recheck oil level
   
   • Start the engine and let it idle for about a minute. Do not rev the engine or ride immediately.
   • Shut off the engine and let the oil settle for a few minutes.
   • With the motorcycle upright and level, check the sight glass again. Top up if needed to bring the oil to the correct level.
8. Inspect for leaks and reinstall skid plate
   
   • Inspect the drain plug, filter covers, and screens for leaks.
   • Reinstall the skid plate, tightening its bolts securely back in place.
9. Dispose of old oil and filters responsibly
   
   • Take used oil and filters to a local recycling facility or auto parts store that handles hazardous waste.
