Hey Mouse,
My back was kind of hurting too. I am only 5'9" and my arms are kind of short. I got aftermarket risers 5 1/2" up and back and it has really helped. I can now sit up if I want to and don't have to reach as far forward. I did have to drill out the mounting holes as they use 1/2" bolts instead of Triumph's captured bolts with nuts. Also, the solo seat moves you a bit more forward than the stock speedie seat. My hands don't fall asleep anymore either. Hope this helps.
Dan
