I've noticed that tire pressure makes a remarkable difference in handling on my 600. Be careful with those liter bikes because they will slip out from under you at full lean even if the tires are warm. That is the reason why I like 600's because they are lighter and don't have as much power as the 1000's do. And the 600's are not as wide as the 1000's.
That's just my opinion, take it or leave it for what it's worth.
Bike tested the tire warmers that racers use in December I think it was. (It's under a pile of paperwork somewhere)
Their test concluded that after the warmers come off the Bike and its sat on the grid for as long as they are there is an almost negligable difference between the tires tempterature and the ambiant tempterature.
The test concluded the two best things for warming a tire up were 1) The Sun and 2) Riding the bike.
The Metzelers on my Radian did a great job of communicating how they were. When they were cold, you could feel they were less sticky. Leaned over in a corner, they let you know they weren't warm enough. It's just a feeling I got, not sure how else to describe it.
