Step-by-Step Guide

1. Prepare Your Bike

Ensure your KTM 125SX is on a stable surface and the engine is cool to the touch. Disconnect the spark plug wire to prevent accidental starting.

2. Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully remove the old spark plug. Turn counterclockwise until it is loose enough to remove by hand. Inspect the old plug for any signs of damage or wear, which can indicate engine issues.

3. Install the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug. This will make future removal easier and prevent thread damage. Carefully thread the new spark plug into the engine by hand to avoid cross-threading.
