May 21, 20215 yr 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!
May 21, 20215 yr 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
