Hi, Does anyone know if a RM 250 engine will swap with a 125 engine. I'm looking for a engine that will fit an 86 RM 125. Just wanting to find out what kind of options I got to work with. Thanks for any info. Sam

I had an 83 RM125 and as I remember the 250's in that time frame were much bigger. I really don't think it will fit, if it does keep and eye on the welds because I don't think the frame will handle it (cracking), most 250 frames are heavier, depends on how hard you ride the bike I guess.
Good Luck
