Changing the oil in your 2017 KTM 250 EXC-F is a critical maintenance task that keeps your engine performing at its best and extends the life of your dirt bike. Here's a step-by-step guide that's proprietary to MotoSport.com, including essential tools, specifics for your model, and pro tips for KTM owners.

Tools and Supplies Needed

  • 13mm deep socket and ratchet
  • Torque wrench (for proper bolt tightening)
  • Oil drain pan
  • Gloves (recommended for safety and cleanliness)
  • OEM oil filter – Part number: 77338005100 (or high-quality aftermarket equivalent)
  • New engine oil – Recommended: SAE 15W-50 (0.8L, Motorex Top Speed 4T or equivalent)
  • Clean funnel
  • Clean cloths or paper towels
  • Replacement copper crush washer (for drain plug, if needed)
  • Flathead screwdriver (if needed to remove skid plate)

Step-by-Step Oil Change Procedure

  • Warm up the Engine
    Let the engine idle for a couple of minutes. This warms the oil so it flows out smoothly when you drain it. Turn the bike off and ensure it's secure on a stand.
  • Remove Protection/Skid Plate
    If your 250 EXC-F has a skid plate, remove it for easier access to the oil drain bolt and oil screen.
  • Clean Around Filler Cap
    Wipe down the area around the oil filler cap to prevent any dirt from falling inside when you open it.
  • Remove the Oil Filler Cap
    Unscrew and set aside the oil filler cap on the right side of your engine. This step will help the oil drain faster and more completely.
  • Drain the Oil
    Position the drain pan under the engine. Using your 13mm socket, loosen and remove the oil drain bolt (bottom of engine). Watch for hot oil. Remove the copper crush washer as well; replace if it's worn or damaged.
    Specific to 2017 KTM 250 EXC-F: The drain bolt is magnetic and may collect small metal fragments—inspect and clean thoroughly.
  • Remove and Inspect the Oil Screen
    The oil screen is located near the drain bolt. Use the 13mm socket to remove and carefully extract the oil screen. Clean it with brake cleaner or solvent and inspect for debris or metal shavings. Reinstall after inspection.
  • Remove the Old Oil Filter
    Remove the oil filter cover (right side case) using the necessary tool. Take out the old filter. Inspect for any abnormal debris; this can be an early indicator of engine wear.
  • Install New Oil Filter
    Lightly oil the new filter's rubber gasket. Insert it into the engine and replace the cover, tightening bolts to the manufacturer's torque specification. (Refer to the owner's manual for proper torque values.)
    Pro Tip: Always use OEM KTM filters or reputable brands for optimal performance and fit.
  • Replace Drain Bolt and Oil Screen
    Place the cleaned oil screen and the drain bolt (with a new crush washer if needed) back into position. Tighten both to the specified torque in your KTM service manual to avoid stripping the aluminum threads.
    2017 KTM 250 EXC-F Callout: Over-tightening the drain bolt can strip the threads in the magnesium cases—use a torque wrench.
  • Add New Oil
    Using a clean funnel, pour in 0.8 liters of new SAE 15W-50 oil through the filler port. Pause periodically to avoid overfilling.
    Checking oil level: The 2017 EXC-F does not have a dipstick. Use the sight glass on the engine case to verify oil level when the bike is vertical (not on its side stand).
  • Reinstall Oil Filler Cap & Skid Plate
    Tighten the oil filler cap and reinstall the skid plate securely.
  • Start Engine and Recheck Oil Level
    Start the engine and let it idle for about 30-60 seconds. Shut it off, let it sit for a minute, and then check the oil level again at the sight glass. Top off as needed.
    If oil level is low after circulating, add small amounts until oil is centered in the sight glass.

Model-Specific Tips and Callouts for the 2017 KTM 250 EXC-F

  • Drain bolt threading is in soft magnesium cases. Use a torque wrench and do not exceed recommended torque.
  • Magnetic drain bolt—inspect for metal particles at each oil change.
  • Recommended oil volume: 0.8 liters (0.84 US qt); always check via sight glass when the motorcycle is upright.
  • KTM oil filter access is straightforward—no special tools required beyond your socket and ratchet set.
  • Replace the crush washer every few oil changes to prevent leaks.

Final Checks and Safe Disposal

  • Dispose of old oil and filter responsibly at an approved recycling center or MotoSport.com participating dealer.
  • Double-check for leaks after warm-up and re-tighten bolts if needed, but never force bolts tighter than specified.
  • Record the date and hours on your bike after the oil change for accurate maintenance intervals.

Following these steps ensures the engine on your 2017 KTM 250 EXC-F stays protected for your next ride. For OEM parts, filters, oils, crush washers, and everything else you need, trust MotoSport.com—your partner in dirt bike care.
