Rhoda_Sodapop Posted May 21, 2021 Report Share Posted May 21, 2021 I have inherited a Bultaco engine with the number RM-19802534-A. It is a 250 engine but I have no idea if the 'RM' at the beginning of the serial number has any significance. Any help would be appreciated!

feetupfun Posted May 21, 2021 Report Share Posted May 21, 2021 RM is one of the prefixes Bultaco used on engine numbers. The R is the capacity and the M is for motor. The A at the end means it is from a model 198A not from a model 198 1 Quote Link to comment Share on other sites More sharing options...

model80 Posted May 23, 2021 Report Share Posted May 23, 2021 (edited) His is a list of the Prefix Letters, that I came across some years ago, I’m afraid I cannot credit the source of the document as I cannot recall who the Author was.
