07 250 motor in previous year frame?

Recommended Posts

Have a 2007 RM250, cracked the frame while pressing out the swing arm bolt. Got it welded but if I could find a frame cheap I would rather swap it out with one that hasn't been welded on. Will my 07 motor fit in any previous year frames without modification? Obviously if I have to buy new head mounts to make it work that is okay but not if the frame would need to be altered. 

 

Thanks

Hmmm... I am pretty sure 04 had the motor at a slightly different angle, and that was changed in 05, where it remained the same until they stopped production (08 in the US, 11 or 12 in the UK or OZ I think.) So I believe  you are ok with 05+ but I'd wait until someone who was SURE posts! 

 

Good luck. 

 

EDIT: I think this is the thread I read that gave me the 04 change idea... although reading the post it sounds like maybe that change happened between 03 and 04?

Lot's of threads on the changes, you may be able to find even more info;

Thank you! Been doing a lot of googling and have concluded it will most likely be okay. Maybe have to buy new motor mounts to match the year of the frame which would be okay. But it would be great if someone on here told me they swapped an 07 motor into an 04 or vice versa and it bolted up perfectly!
