This - Pilot Activ. Had them on GS500 - great all-around tires. Someone else recommended Rosso. I have Rosso II on my CBR, great tires too, but more expensive, and I don't notice any excessive wear (Rosso II, not Rosso Corsa).
I've just been told that the Pilot Activ tires are discontinued. It wasn't clear if the entire line is discontinued or only in these particular sizes. Michelin introduced some new tire models this year with one line specifically targeted at smaller bikes like the CBR250 and Ninja 300; the Michelin Pilot Street. Radial tires available in 110/70-17 front and rear 130/70-17 or 140/70-17. I believe they're already available in some international markets but not sure when we'll see them here.
