Dirtbike schematics?

Is there any where I can get schematics for dirtbikes? I need to know some frame geometry and motor placement measurements. I need the measurements for a KTM 640 or 690. Any help or suggestions?

I've never seen anything like that, and it's doubtful that any OEM would post a print of their frames. So I believe that the only way that your going to get information like that is to get a bike and measure it yourself.

Being in the US you might be able to get something from ATK, but even that would be a long shot.
