  • The drain plug and oil filter screen are located on the left side when sitting on the bike.
  • Skid plate removal is simple: just turn the quick-release pin and the plate drops off the frame. Secure it somewhere safe.
  • Total oil capacity is around 1.0 to 1.1 liters (1.1 L is typical—always check your sight glass).
  • Be careful not to overtighten the drain plug or oil filter cover; recommended torque for the oil filter cover bolts is 7.4 Nm (very light).
  • The oil level should sit between the marks on the engine's sight glass and is best checked with the bike upright on level ground.
  • KTM recommends Motorex 10W-50 (for most conditions) and changing the oil roughly every 15 hours for hard riding, or every 20–30 hours of casual use.

Step-By-Step Procedure

  1. Warm up your engine for a few minutes to thin the oil for easier draining.
  2. Remove the skid plate. Use the quick-release pin KTM supplies: simply turn and detach.
  3. Place a drain pan under the engine's drain plug (13mm bolt, lower left side when seated). Loosen the plug carefully—apply gentle inward pressure while unscrewing to prevent the plug from dropping into the pan with the hot oil.
  4. Allow all oil to drain. Tilt the bike slightly (upright) to get the last drops out.
  5. Remove the oil filter cover bolts (8mm), accessing the oil filter. Let any residual oil in the filter chamber drain.
  6. Remove the oil filter and inspect for debris or metal filings. Insert a new, clean oil filter. For best results, fill the new filter about 1/3 full with fresh oil before installation, as suggested in the manual for optimal lubrication at start-up.
  7. Clean and inspect O-rings and sealing surfaces on both the drain plug and filter cover. Replace if worn or damaged.
  8. Reinstall the oil filter cover and snug the bolts by hand. Using a torque wrench, tighten the cover bolts to 7.4 Nm (65 in-lbs). Do not overtighten.
  9. Reinstall the drain plug using the 13mm wrench, hand-tight then torque to spec (typically 15 Nm, always verify for your exact model).
  10. Add fresh oil at the filler cap (right side, under seat area) using a funnel. Pour in about 1.0 liter, then check the sight glass.
  11. Start the engine and let it idle for 2–3 minutes. Shut off and let settle for a few minutes, then check the oil level again.
    • If needed, top off so the oil is in the middle of the sight glass circle when the bike is upright and level.
  12. Inspect for leaks at the drain plug and filter cover area. Reattach the skid plate.
  13. Dispose of used oil and filter properly at your local recycling center.
