One reason that the sag dimension can and will vary from stock suspension vs. those with suspension work is that taken by themselves, the sag numbers don't say anything about the amount of front end dive that occurs at the turn entrance. That does often change once the forks are redone. Some people, especially those who rely heavily on the rear brake, or who don't brake very hard entering a fast turn, will have more trouble with the front end pushing that those who brake hard. Rule of thumb, the more the front compresses, the better the turn in.
Some might want to read this as well, or not:
Thats deff. not me Its either brakes or gas. I am a front brake man all the way riding sport bikes for the past 10 years has kinda made me that way. I have actually bottomed in several turns being on the tank and brakes so hard. I dont know gray but I am with these guys the bike pushes, and i cant get mine to stop.
