I think I have hit on a good combo for my riding style. I tend to do spirited rides on backroads and country highways. And very, very seldom in the rain and no track days. I have had a Pirelli Diablo Rosso II on the front (approx 1000 miles) and a Pirelli Angel GT (for approx 2600 miles) on the rear. Hey, at least they are from the same manufacturer, although the Angel was made in Germany and to Rosso II in (gasp!) China. I really like the way the bike feels.
I had no real beef with the stock Dunlops, except that the rear did not last very long. The Rosso II is a bit of a sport tire that offers really good grip and wears reasonably well on the front. The Angel GT is a sport touring tire that seems to have good grip and excellent wear. I am thinking it should go at least 6,000 miles on the rear.
