I recently bought a used 2003 rm125 to play around on and last night I was going to pull the head off to check the piston and noticed the bike has a bkr5egp spark plug in it. Is this the plug the bike usually uses? I looked up the reference online and it looks like it’s a car plug. A little confused thanks for the help.

R6918B-8 this is the plug fro the bike you need this because the electrode will brake off in the cylinder and destroy the top end

Thank you. Any idea why he would have that plug in there?

Because the one it calls for costs a lot more money.
