Recently I have replaced my old Michelin Pilor Roads 2, with Michelin Pilot Pure's and have been experimenting with different tire pressures.
So far I have noticed the following. With the OEM recommended tire pressure of front 36psi back 42psi, the turn in has gotten noticeably quicker as compared to the old (worn Road 2s). When I dropped the pressure to 28psi front and 32psi back, I noticed the following:
Tires warmed up much faster, but the "stickiness" when cornering didn't improve much and the "turn in" has became sluggish (worse then the old tires) and the general feel is that the turn radius has increased. So, I"m going to increase the tire pressure to 38psi back and 32 psi front and see if I can find the happy medium between the stickiness and the turn in. Will update this entry in a few days.

Changed the tire pressure to 40 psi -rear and 34 psi - front. My motorcycle turn-in is SO MUCH BETTER and tires stick just as good as with lower pressure before.
