I have had Dunlop D220
the fronts are pretty good, as they don't cup and lasted about 8,500 miles
the rears, however did not stand out so well, and die about 5,000 miles
I replace them with the BS021
the front is aweful, I only put about 1,500 miles on and already, they are flat spotting on the front. I have not put the rears on.
the best tire that I had on my K1200RS is the Metezler Z-6, they don't cut and stay round and last quite a while.
I was thinking of replacing with Metzeler M880, but they are V speed rated. They should last a bit longer but if anyone had experience with V speed tires, rather than Z speed tires, please post your observations and let me know
