Shop parts for a 2017 KTM 300 XC-W Dirt Bike.

Regular oil changes are crucial for the longevity and performance of your 2017 KTM 300 XC-W. This two-stroke dirt bike uses a separate transmission (gearbox) oil, not engine oil like a four-stroke. Follow this detailed guide to keep your ride in peak condition and avoid costly damage.

Tools and Supplies Needed

  • 13mm socket and ratchet (for drain bolt)
  • 8mm socket or wrench (for oil level check bolt)
  • Torque wrench
  • Drain pan
  • Funnel
  • Rag or paper towels
  • Replacement gear oil – 75W/80W or as specified by KTM
  • New washer for drain bolt (recommended)
  • Gloves (optional, but highly recommended)

Preparation

  • Ride the bike or let it idle briefly to warm up the oil. Warm oil drains faster and more completely.
  • Put the bike upright or lean it on its side stand. Placing it slightly leaned over makes draining easier, per tech tip.
  • Place the drain pan under the engine, on the right side of the frame.

Model-Specific Call-Outs for the 2017 KTM 300 XC-W

  • The drain plug is located on the lower right side of the engine and is accessed with a 13mm socket.
  • The fill and oil level check bolts are both on the right side—the level bolt is 8mm and situated lower on the clutch cover.
  • A magnetic drain plug is standard, so inspect for metal particles. Excessive debris could indicate internal wear.
  • The oil capacity is 800 ml (milliliters).
  • If you have a skid plate, it can make access tough—some riders use drain plug extension tools or loosen the plate slightly for extra room.
  • Torque specs are: Drain plug – 20 Nm; Oil level bolt – 10 Nm.

Step-by-Step Oil Change Procedure

  1. Remove the Drain Bolt
    • Using your 13mm socket and ratchet, loosen and remove the drain plug on the right side bottom of the case.
    • Be sure to catch the washer - replace it if it looks damaged.
    • Allow the oil to fully drain - typically wait 5–10 minutes.
    • Inspect the magnetic tip for any metal shavings; clean both the plug and washer thoroughly.
  2. Reinstall the Drain Plug
    • Reinstall the drain plug and washer once draining is complete.
    • Use a torque wrench to tighten to 20 Nm to avoid stripping threads or leaks.
  3. Refill with Fresh Oil
    • Locate the fill cap on the right side of the engine.
    • Insert a funnel and pour in 800 ml of the specified gear oil.
    • Check for overflow. Clean any spillage immediately.
  4. Check the Oil Level
    • Remove the 8mm level check bolt (below the fill cap).
    • With the bike upright, oil should just begin to trickle out from the level bolt hole; this means the correct amount is inside.
    • If no oil comes out, add slowly until it does; if excess pours out, let it drain until it slows to a trickle.
    • Reinstall the level check bolt and torque to 10 Nm.
  5. Final Steps
    • Double-check both bolts for tightness and wipe away any oil residue.
    • Start the bike and let it idle for a minute.
    • Inspect for any leaks around drain or level check bolts. Tighten further if necessary, but do not overtighten.
    • Properly dispose of the old oil at your local auto parts store or recycling center.

Maintenance Tips

  • Change the transmission oil every 10–20 hours of riding, or more frequently if riding in harsh conditions or racing.
  • Always use high-quality oil recommended by KTM to maintain clutch and transmission life.
  • Inspect your magnetic drain plug every change; persistent debris is a red flag for possible gearbox issues.

Conclusion

  • Routine oil changes on your 2017 KTM 300 XC-W are straightforward and essential.
  • Following the correct procedure and using the right supplies will help you maximize the lifespan of your transmission and maintain smooth shifting and clutch performance.
