It is usually stamped into the metal and can be difficult to read due to dirt and grime. You may need to use a wire brush or a small scraper to clean the area before you can see the number clearly.
Here's a more detailed breakdown of where to look:
1. Right side of the engine: Locate the right side of the engine case, near the clutch cover.
2. Near the clutch cover: Look for a flat surface or a raised area on the engine case near the clutch cover.
3. Stamped number: The engine number will be stamped into the metal of the engine case.
Important:
* The exact location of the engine number may vary slightly depending on the year and model of the RM 125.
* If you can't find it, consult your Suzuki RM 125 owner's manual or contact a local Suzuki dealership for assistance.
