This an original 1985 printing of the Yamaha YX600 Radian assembly manual. I scanned my own and converted it to PDF in a size suitable for the web.  There were mechanical changes made to this bike during the five years it was produced (1986-1990).  I do not know if this manual includes all changes and / or all versions. 

If you purchased your Radian unassembled in a crate direct from Yamaha and haven't gotten around to putting it together yet, this manual could be helpful.  (lol)  Seriously, there are some useful things here, like cable and wire routing, torque specifications, etc.  If nothing else, it's at least sort of neat and interesting.
