Just another quick commentary on the Stock Dunlops...
Do you REALLY want to leave the tires from the lowest bidder on your bike?!?
When I went from the Dunlops to the Pilot GT's, I immediately picked up about 10-15 mph in the corners, simply because they felt more solid. I'm running a mismatched combo now (Pilot GT front/Avon Venom rear), which still feels more solid than the Dunlop 700/701's did...
Also, I do NOT miss the centerline groove. having the tire tracking rain grooves, cracks in roads, etc. is something that always weirded me out. Pilot GTs, Avon AM41, and some other tires do away with these.
That being said, the OEM Dunlops are usually reasonably priced, but I think there are equally good deals on some other tires out there. And a lot of us here do get that tires are a personal preference, so if you really LIKE the OEM Dunlops, that's your call! Some of us just won't understand why...
