I believe it's a matter of getting used to a certain pressure at the track as opposed to the street, but as we both know they are two entirely different animals. I've found from personal experience as well as from those on the street that if they're running any lower than the stock psi the bike feels sluggish in the front and slippery in the rear in the twisties. That's what the suspension's for, let it do it's job, and the tires will do theirs.
