RM 125 swap

[350red]

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

I'll be staying with the 125 engine, another guy told me the same thing. Thanks, Sam

smart move with some bending and welding it will go but then what you have is an over powered off ballance death trap lol. dont get me wrong I like speed but I like to know that my frame will hold up @ 80 or so you know lol
