Do motorcycle tires have to "break in"?

I just got two new Dunlops, they feel Weird. I've bought old, used and new tires in the past, for my Honda and my Harley, a new Kenda and an old , used Shinko. They felt Fine from day one. Are Dunlops Like this, nowadays, or are they defective?
Update: I found 32 PSI front, 40, back. Technically, this is for 2-up. I reduced them to 30/36, as book says. The slippery feel of the front is still there. But, only 29 miles on them.
