V-Strom Riding position/back pain

Need a favor, there is a thread someplace on here that went into this, and I cannot find it. I think the OP, sold his bike over it and went to a sportbike. Post the link pls if you can.

The point was I think, that the upright seating position actually caused him more pain than the leaning forward riding position of a sportbike. That was a new one on me, and I want to read the post again. Thx
