That front tire wear pattern's not really unusual for a quick pace on the road. You're carrying decent corner speed and thus pushing the front, but on a bike like the Pani you're just not really hammering the throttle off the corners like you would on track, not unless you spend a lot of time at seriously illegal velocity. And on those times you are giving it some stick, the magic orange light on the dash is telling you why the rear tire wear isn't worse than it is. Turn the TC down/off and see how the rear tire fares then...
Strangely, this wear pattern never happened before with my GSX-R1000, although I did not change my riding style or speed. The only real difference is probably more speed at the exit of corners (because I can trust the TC and don't have to be afraid of high siders). Just wanted to be sure that its not a set up issue which can be adjusted. 
Thanks Steve B fpr your appreciation of my road pace
The guys at my dealership told me that the front tyre wears because I'm breaking into corners too much and that I should adjust my EBC, in order to brake more with the engine. But the front tyre is mostly worn at its side, not in the middle. That, to my understanding, shows its working hard at corner exits, when the bike is leaned over.
I always though that when your riding skills improve, you would start using more rear tyre? And I wonder how people can get 4000 miles and more out of a set of Pirellis!? Are they driving on ice?
I think the dealer is partly right about it being due to braking into corners. However, while it's always worth experimenting, I don't think dialing in more engine braking is necessarily the answer (if there is one, other than new rubber), or that it means you're doing anything wrong at all. I just think that with a liter bike on the street, while in order to have a bit of fun you will carry some corner speed, unless you tend to be running at ton-up pace a lot you just aren't really whacking the throttle open off the corners, which is what you'd do on the track. Do that on the street and you'll be at warp speed on every straight bit of road. Easily doable of course, but probably not such a good idea in regular practice...
I trail brake nearly or to the apex myself, and end up shaving the sides off my fronts. My rears tend to wear pretty evenly in season, and more in the middle in the cooler months since the grip's lower and you're not jumping off the corners as hard as in Summer. I find that in Summer I will usually run a lower gear in a given corner and with the resulting higher rpm/power, like a bit more TC and less EBC. Then in the other seasons, I carry a higher gear and run less TC and more EBC. All the tires I've run on the Pani so far (SP's, Q3's, S20's) have exhibited this pattern more or less, and have lasted about 2500 miles +/- a few hundred.
Bottom line, I think wear patterns in street riding tell you more about your environment and riding style than about setup.
