If you remove the Black panel on the left side as though you are going to remove the battery. You will see the spark plug on the left side of the engine.
Local auto part stores will carry all parts available and if they do not have it in stock will special order them. If that fails the a dealership can be contacted to order the part directly from Peugeot.
What is the spark plug gap for a 2006 yamaha ttr 125?
It appears to be NGK r6918b-8. Doing a little searching I found the spark plug above listed as: "NGK special spark plug for (1996-2000) RM 125." This same spark plug is listed in the 2003 RM 125 Service Manual as the correct spark plug for that engine.
The spark plug for this bike is Ngk Br8es.
