Spec 5
I LOVE it!
I've only put about 30-40 miles on it. Still getting used to it, but part of the problem is that I need a tune BAD, so once that is sorted out, i should be good

I haven't stomped on it really bad yet, but its nice
pedal pressure is heavier, but nothing to tired out your legs
squealing isn't as loud as I thought...almost sounds like your chirping the tires
I've already started to figure out how to avoid the squealing, so I'm sure I'll get it to go away
Just wanted to post for those interested!
at least thats what it said on the web site I was on. I'm trying to figure out what will work with the stg 5 to see what my options are.
