I have a sport/touring background but am too old to do that safely anymore, hence the Ryker. Does anybody have experience with both the 900 ACE and the Rally? Specifically, does the upgraded suspension on the Rally translate into better handling or perhaps a more comfortable ride? Do the rally tires detract from the handling on pavement? Is the standard Rally seat as comfortable as the optional Driver's Comfort Seat? Is the optional Sway Bar worth installing in terms of improved cornering ability? Lots of questions I know but I want to make the best choice.
