While it's theoretically possible to mount a 2001 KX 250 motor in a 1999 KX 125 frame, it would require significant modifications. The mounting points, engine size, and overall geometry differ between the two models, which could lead to issues with fitment, balance, and handling. Additionally, you would need to consider compatibility with the transmission, cooling system, and exhaust. Therefore, while it may be an interesting project, it would involve extensive work and expertise.
yes it can i have done it
No a 125 frame is too small to fit a 250 motor but with a cutting torch and a welder anything is possible.
No it won't only 1999-2002
Yes, a 1995 RM 125 motor can fit into a 1990 RM 125 frame, but there may be compatibility issues that need to be addressed, such as mounting points, wiring harness connections, and exhaust alignment. It's essential to check specific measurements and components, as well as potential modifications required for a proper fit. Overall, while it's feasible, careful consideration and adjustments may be necessary for a successful swap.

There may be clearance for the motor to fit in the frame, but you will have to modify the frame to bolt the motor into it. A main concern would be how the back of the motor lines up for the swingarm shaft to go through. Also will the carb intake boot line up with the airbox boot? A lot of questions you wouldn't know until you (or someone else) tries it.
Will a 94 rm 125 engine fit on a 2000 rm frame?
How much oil does a 2001 Yamaha TTR 125 hold? How much oil does a 2001 Yamaha TTR 125 hold? How much oil does a 2001 Yamaha TTR 125 hold?
The yz 125 is better because 2005 and up have An aluminum frame and over all better. The kx 125 is ok but they made an aluminum frame in 2007. I would always go with yamaha
on the frame
The TS125 engine will fit straight into the TS100 frame. My TS100 has a 125 in it and it rides very well.
