After running thru a set of Pilot Road 3's in 12k miles, I put on a set of Pilot Road 4's, including the 2GT rear tire since I do ride 2 up fairly frequently. It works just fine whether I'm riding single or 2 up on the Norge, odd advice given earlier about it being squirrely unless it's a heavy cruiser is accurate since it's working very well on the Norge. So far, I've got about 6K miles out of them, and easily 1/2 the tread depth left from what I see. Excellent tire, supremely stable in wet and dry conditions, sticky and plenty of grip when leaned over...love the tire so far!
