Frame?

[Matt400ex_17]

Can you put a 400ex motor in the 250r frame? If possible how hard is if hard at all?? and is this much stronger or better than the 400ex frame??

Anything is possible, but i dont think it would handle too great.

Plus the 400ex frame is alittle taller than the 250r frame since the big thumper motor is so tall.
