Hello everyone,
I have a 2006 RM450. The bike came with a title that has a VIN number and an engine serial number. The engine serial number does not match what is on the title. I was wondering if anyone knows how to identify my engine? the number on the engine is L401-117749. thanks, Dan

 

so there is no way to tell what year this engine is from the engine number?

 

nope...............
