SR mag did a review in the last issue on like 20 different dampers...including graphs on how they performed. Personally, I think a damper where you forget it's even there is the way to go on a 12r. You'll most likely set an adjustable one to one setting 99% of the time on that bike and never touch it. But that's just my opinion. I didn't like the scotts on jesters 929 until I turned it almost all the way down. Otherwise...I felt like it was just irritating.
