I measured from the seat front to the rod holder bar and it's 18 inches, at the length I can set my hand on any of the rods at arms length because the holders actually face back toward me. I'm not stretching just straightening my arm and laying it down. To give another reference point the bar is 12 inches behind my foot pegs. The new one will be two inches closer but I mainly did that because I was raising the height. I figured if I only raised it it might get a little far away from me.
Here's something else I've been working on the last couple of days.
