I noticed that the new-to-me Valkyrie I recently bought had tires from 2011.

Wish I had noticed that BEFORE I took my 700+ mile trip to the Texas Twisted Sisters!!!
Anyway got a set of Michelins this week. Exedra max for the rear and G107 or G701 (something like that) for the front. They're starting to get broken in now, I have maybe 35-40 miles on them and I cannot believe the difference! I've gone darkside on previous valks, I've run metzlers and dunlops and even Venoms. But this gives me the best grip I can recall and they're not even broken in all the way yet. I'm doing tight figure 8's in an open lot and it just feels smooth and grippy. I'll report back after my trip the tail of the dragon in May. But my initial impression is WOW!
Just thought I'd share in case anyone was curious.
Cheers!
