I've been using Shinko SR568 rear tires on my 2011 Burgman 400. I got about 6000 miles on the first rear tire, and am just shy of 6000 miles on the second tire, which I am about to replace with another SR568. I might not be very discerning about tires, but I've not had any issues at all with the SR568. I do run the tires until the strings are nearly showing, so you might not get as many miles as I have gotten. At about 20K miles, I replaced the factory front tire, which was cupped pretty badly, with the Shinko SR567, which is working fine (I've just turned 22K miles on the bike). I ride the bike hard - pretty much every acceleration is full throttle; a friend kids with me, saying that I could replace my throttle with an on/off switch. :grin
