Step by Step Instructions
Step 1: Warm the Engine
Start the bike and let it idle for 3 to 5 minutes, or take it on a short ride. Warm oil thins out and carries suspended metal particles and combustion byproducts more effectively. Do not drain oil from a completely cold engine — you will leave a significant amount of contaminated oil in the sump.
Step 2: Park and Level the Bike
Park the motorcycle on a level surface and engage the paddock stand or center stand. The bike must be perfectly vertical for an accurate oil level check later.
Tip: If your bike has a belly pan or aluminum skid plate (common on adventure-touring builds), remove it now using the appropriate fasteners. Keep all hardware organized.
Step 3: Remove the Oil Fill Cap
Locate the oil fill cap on the right side of the engine crankcase. Remove it by turning counterclockwise. This allows air to enter the crankcase so oil drains freely and completely.
Warning: On the 1290 SAS, the fill cap is near hot engine components. Touch only the cap, not surrounding metal.
Step 4: Position the Drain Pan
Slide the oil drain pan beneath the drain plug on the bottom of the crankcase. Ensure your pan has at least 5 liters capacity — the LC8 holds approximately 3.8 liters and oil will surge out quickly.
Step 5: Remove the Drain Plug
Using a 14 mm hex socket, loosen the drain plug by turning counterclockwise. Once broken loose, finish unscrewing it by hand. Be prepared for hot oil to flow immediately.
Warning: Oil will be hot. Always wear nitrile or rubber gloves and safety glasses during this step.
Step 6: Drain All the Oil
Allow the oil to drain completely for 10 to 15 minutes. While it drains, inspect the drain plug threads for stripping, cross-threading, or metal debris. A few fine metallic particles are normal on a high-stress LC8 engine, but large flakes or chunks indicate internal wear that requires professional inspection.
Step 7: Replace the Drain Plug Washer
Remove the old copper crush washer from the drain plug bolt. Replace it with a new one every single oil change. Copper crush washers deform permanently to create a seal — reusing them is the most common cause of post-change leaks.
Step 8: Reinstall the Drain Plug
Clean the drain plug threads and the mating surface on the crankcase with a clean rag. Thread the drain plug in by hand to avoid cross-threading. Once hand-tight, use your torque wrench to tighten to exactly 30 Nm (22 ft-lbs).
Important: Do not over-torque. The LC8 crankcase is aluminum alloy. Stripping the threads requires expensive helicoil repair or crankcase replacement. Always use a torque wrench.
Step 9: Remove the Old Oil Filter
The oil filter is located on the right side of the engine, below the cylinder. Position your drain pan underneath to catch residual oil. Use a strap-type filter wrench or a 76 mm 14-flute cap wrench to loosen the filter, then unscrew it by hand.
Tip: If the filter is difficult to reach due to frame or exhaust components, a flexible-strap filter wrench provides the best clearance in tight spaces.
Step 10: Inspect for Double Gaskets
Once the old filter is removed, inspect the engine sealing surface to confirm the rubber gasket came off with the filter. If the old gasket has stuck to the mounting surface, carefully pry it off with a flat tool — do NOT install the new filter over an old gasket.
Warning: A double gasket is the #1 cause of catastrophic oil leaks after a filter change. Always visually confirm the sealing surface is clean.
Step 11: Prepare and Install the New Filter
Apply a thin film of fresh 10W-50 oil to the rubber gasket on the new filter with your fingertip. This lubricates the seal and ensures easier removal at the next service. Screw the new filter onto the engine by hand. When the gasket makes firm contact with the sealing surface, turn it an additional 3/4 turn by hand. Do not use a wrench to tighten.
Step 12: Add New Oil
Place a funnel into the oil fill port. Pour in approximately 3.5 liters of SAE 10W-50 fully synthetic motorcycle oil (JASO MA2). This leaves about 300 ml to reach the 3.8 liter full capacity after the new filter has absorbed oil.
Important: Only use oil labeled JASO MA2. The 1290 SAS uses a wet multi-plate clutch, and automotive oils with friction modifiers will cause clutch slippage, accelerated wear, and potential transmission damage.
Tip: Good oil choices for the LC8 engine include Motul 7100 10W-50, Castrol Power1 Racing 10W-50, Mobil 1 Racing 4T 10W-50, or the OEM KTM Performance synthetic blend.
Step 13: Circulate and Check Oil Level
- Reinstall the oil fill cap (hand-tight only for now)
- Start the engine and let it idle for 2 to 3 minutes — this circulates oil through the new filter
- The radar-assisted adaptive cruise control and semi-active WP XPLOR suspension electronics do not need to be disabled for an idle oil check, but ensure the bike is in neutral with the sidestand up
- Turn off the engine and wait 2 to 3 minutes for oil to settle back into the sump
- Remove the fill cap and check the level — you should see oil at or near the fill opening on the LC8 engine
- If the level appears low, add oil in 100 ml increments and recheck
- Final capacity should be approximately 3.8 liters total with filter
Step 14: Final Inspection
- Check around the drain plug for any seepage
- Check around the oil filter gasket for leaks
- Reinstall and torque the fill cap securely
- Wipe down any spilled oil from the engine cases and frame
- Reinstall the belly pan or skid plate if it was removed
- Reset the service interval reminder via the TFT display menu: navigate to Settings > Service > Reset Oil Service
Step 15: Test Ride
Start the engine and verify the oil pressure warning light goes out within a few seconds. Take a short test ride (2 to 3 miles) and listen for unusual noises. After parking, inspect the filter and drain plug area one final time under the engine.
Tips, Warnings & Common Mistakes
Helpful Tips
- The LC8 engine responds best to high-quality 10W-50 synthetic. Do not substitute 10W-40 or 5W-40 — the KTM service manual specifies 10W-50 for a reason on this high-output engine.
- Always keep spare copper crush washers and an extra oil filter in your tour luggage for long-distance adventure trips.
- The 2025 1290 SAS features multiple riding modes and semi-active WP XPLOR suspension. None need special handling during an oil change, but avoid jarring the sensor modules on the front fork and rear shock during the procedure.
- Record date, mileage, oil brand, and filter part number in a maintenance log for warranty documentation.
Warnings
- NEVER use automotive passenger car oils labeled "Energy Conserving" or with friction modifier additives. The wet clutch in the LC8 will slip and degrade rapidly.
- NEVER run the engine without verifying oil was added. Oil starvation on the high-performance DOHC LC8 causes catastrophic bearing and cam failure within seconds.
- ALWAYS use a torque wrench on the drain plug. The aluminum crankcase threads are easily stripped by impact wrenches or unchecked hand force.
- Do not change oil with the kickstand down — the bike will not be level and your oil level reading will be incorrect.
Common Mistakes to Avoid
| Mistake | Consequence | Prevention |
|---|---|---|
| Over-torquing drain plug beyond 30 Nm | Stripped crankcase threads, oil leak | Always use a calibrated torque wrench |
| Reusing the copper crush washer | Oil leak from improper sealing | Always install a new washer, keep spares |
| Using automotive oil with friction modifiers | Wet clutch slippage and wear | Verify JASO MA2 certification on bottle |
| Double-gasketing the oil filter | Massive oil leak, engine damage | Inspect mating surface before installing new filter |
| Forgetting to open the fill cap before draining | Slow, incomplete oil drainage | Always remove fill cap first |
| Not circulating oil through new filter before checking level | Falsely high oil level reading | Run engine 2-3 min, then wait and recheck |
| Incorrect oil level (overfilling) | Foaming, pressure issues, seal damage | Add gradually, check level at each step |
Oil Disposal
Used motor oil is classified as hazardous waste and must be disposed of properly. Never pour used oil down a drain, into storm sewers, onto the ground, or into household trash.
- Transfer the drained oil from your catch pan into clean, sealable containers — the empty new oil bottles work well for this
- Bring the used oil to a certified recycling center. Many motorcycle and automotive service shops accept used oil from DIY mechanics
- Major chains that typically accept used oil and filters: - Advance Auto Parts: Free recycling at most locations - AutoZone: Free oil and filter drop-off - O'Reilly Auto Parts: Accepts used oil and filters - NAPA Auto Parts: Call ahead, most locations participate - Local motorcycle dealerships (KTM, Husqvarna): Many accept used oil from customers
- Bring the old oil filter, fully drained. Wrap it in a plastic bag to prevent residual drips.
- Your local municipal recycling program or household hazardous waste center is also an option — check local schedules and drop-off days.
- Never mix used motor oil with brake fluid, coolant, windshield washer fluid, or gasoline. Contaminated mixtures often cannot be recycled.
