Yeah, I've been looking at inflated diameter for the tires I'm considering trying to keep a similar relationship to stock between front and back to avoid the ABS thing.
Regarding ride height, with 14" wilbers out back as long as I stay with a 26" or greater inflated diameter front it will be at least as high as stock at the front of the motor if not slightly higher.
I do get my weight off the bike cornering, habbit from sport biking, and I don't even mentally think about it, its automatic, like leaning forward when I feel lots of torque to counter wheelies, just a habit.
Alpental, I remember reading something like 3lbs front, 7.5lbs rear, saved weight.
