ktm 525 in 400ex frame

[les70]

i have been concidering doing a ktm 525 in a stock 400ex chassis. i came across a 400ex with a blown engine that has works shocks,arms ect for a good price. has anyone done or seen a ktm in a 400ex? i have seen it done in a 250r. is there any major fabrication or issues with this combonation? and what are the pros and cons of using a 525 motor from a dirt bike vs quad?

I seen one back in 06. This guy from ohio had one that was done by jb. It was a stock 400ex frame just modded. He did crack the frame a cpl times. I think that the stock frames are gonna do that more then the 4130 frames. It just depends on what you want to do with it.
