Yes, made a big comfort reach difference.
I still think sometime in the future, I'll be in for a Thunderbike 1.5" T-bar handlebar. But, until then, I can be more comfortable at least.
I didn't notice it so much with the 2 up Touring seat (that's been on my bike since I bought it), but the Standard seat (that's been in a bubble wrap bag) placed up in the rafters in the garage, I just recently swapped in place of the Touring seat. The Touring seat sets me closer to the bars than the standard solo seat/pillion seat does, and even though I'm 6'4", I felt a more comfortable seating position with the Solo/pillion seat, but I felt I had to stretch out to reach the bars, uncomfortably so.
The Risers made a huge difference, Day vs Night type difference.
