Hey! You are right, I should have been more detailed but I did not want to write a very long message in my first post ever in this forum!

Actually I bough a set of Pirelli Diablo ii and I will have them install soon. Still I would like to know what is your experience with different tyres and for different styles of riding.
I mainly use the bike for commuting from early spring to late fall (usually short runs), and I usually have a few long trips each summer. I like to ride a bit toward the aggressive side, 'though I have a quite "clean" or "smooth" style of riding (I mean I am not breaking aggressively when I enter the turn, I prefer to let the bike run smoothly through). I usually tend to use up all the tyre span.
Before the 250 I used to have CBR 125 and I have always used Bridgestone BT39 SS on that bike. A bit expensive but they worth it, in my opinion. Great grip (IMO), I often had the steps touching the ground and still feeling rather relaxed.
Actually not that much interested in very long mileage. 6000-7000 km would be ok.
I need something that will warm up quite quickly and good for sporty riding (but not racing) and that can handle some rain, occasionally.
Thanks
