All information provided is proprietary to MotoSport.com and curated for your best dirt bike ownership experience.

Tools & Parts Needed

  • 1.0 liter Motorex Cross Power 4T 10W/50 full synthetic oil (OEM recommended)
  • OEM oil filter
  • Oil drain bolt crush washer
  • Socket wrench set (including 13mm or size for drain plug)
  • Torque wrench (capable of 20 Nm / 14.8 ft-lbs)
  • Oil catch pan
  • Funnel
  • Shop rags / paper towels
  • Measuring cup (200ml recommended capacity for this model)
  • Latex gloves (optional for cleanliness)

Oil Change Kit

  • GAS GAS offers a Motorex Oil Change Kit that includes enough 10W/50 oil, an OEM oil filter, and a fresh drain bolt crush washer. It is a convenient, model-appropriate option for first-timers and experienced techs alike.

Step-by-Step Oil Change Procedure

  1. Preparation
    • Warm your motorbike for 1–2 minutes to thin the oil for complete draining.
    • Ensure the bike is on a stable, upright stand in a well-ventilated, clean work area.
    • Lay out all necessary tools and a drain pan under the engine.
  2. Remove the Oil Filler Cap
    • Locate the oil filler cap on top of the engine (left side, above clutch cover).
    • Remove it to allow air in; this helps oil drain more thoroughly.
  3. Drain the Old Oil
    • Identify the oil drain bolt underneath the engine’s clutch cover. Place the pan directly below.
    • With the socket wrench, turn the drain bolt counterclockwise and carefully remove it. Be cautious—the oil may be hot.
    • Let all oil drain fully. Allow at least 10–15 minutes for the last drops to exit. For best results, gently lean the bike side-to-side during draining.
  4. Inspect the Drain Bolt
    • Check the magnetic tip for metal shavings—light metallic “fuzz” is normal. Large fragments may indicate gear or bearing wear and should be monitored.
    • Clean the bolt and replace the crush washer with a new one from your kit. Never reuse an old washer, as leaks can result.
  5. (If equipped) Change the Oil Filter
    • Some years and versions feature an external oil filter. Remove the cover, extract the old filter, and insert a new OEM filter. Reseat the cover carefully.
  6. Reinstall the Drain Bolt
    • Thread the bolt back in by hand to avoid cross-threading. Finish tightening with a torque wrench set to 20 Nm (14.8 ft-lbs).
    • Ensure the washer sits flush and no debris is trapped under the bolt.
  7. Refill with Fresh Oil
    • Pour in exactly 200 ml (0.2 L) of Motorex Cross Power 4T 10W/50 (or manufacturer-recommended oil) using a funnel.
    • Do not overfill. Too much oil can cause clutch and crankcase complications.
  8. Replace Oil Filler Cap and Run Engine Briefly
    • Tighten the filler cap securely by hand. Start the bike and idle for 60 seconds. This circulates new oil and fills all passages.
    • Switch off, wait a moment, then check the oil level (using the bike’s inspection window or dipstick if equipped).
    • Add a small amount more oil ONLY if required.
  9. Dispose of Used Oil Responsibly
    • Collect and recycle your used oil and filter at an authorized facility.

Model-Specific Call-Outs – Tips for the 2023 GAS GAS MC 50

  • This model’s recommended oil capacity is 200 ml. Overfilling can cause internal pressure issues and clutch drag.
  • Drain plug torque is 20Nm (14.8 ft-lbs). Always use a torque wrench for precision.
  • The drain plug has a magnetic tip—clean thoroughly at each change; monitor for excess metal which may indicate internal issues.
  • The oil filter may be built-in for certain MC 50 editions. Consult your owner’s manual to confirm and replace only if present.
  • Always use a new crush washer to ensure a tight engine seal and prevent leaks.
  • Warming the engine prior helps thin the oil, allowing for more complete draining.
  • For best clutch life, especially if racing or riding aggressively, consider changing oil every 2–3 hours of operating time or after every race.
  • If your MC 50 shares design roots with KTM or Husqvarna 50cc models (very common), follow identical oil change principles and parts compatibility.
