I am on the 3rd set of tires on mine.
The original Dunlops weren't bad. I wasn't thrilled with the bike losing grip in turns over tar strips, a rather scary feeling, which led me to try different brands.
My next set were Metzeler 888 Marathon Ultras. I wouldn't recommend these, mainly because the front tire is too wide for this bike, rubs the fender mounting bracket (can be corrected with some modification), even though the stated size is correct. These tires also seemed to handle worse as they neared their end of life. I think this was due to the center of the tread, particularly the rear tire, becoming flat as it wore down.
I just installed a set of Shinko 777s. I like the price, and have seen at least one review that described them as very sticky. I've had the bike over 100 mph on these tires, very smooth, no vibration. I just did an 8 hour roundtrip ride this past Saturday, no adverse handling issues at any speed. Traction on tar strips seems to have improved, but hasn't disappeared entirely. There are a couple of downsides to these tires. First, they're not show quality. The whitewall doesn't extend to the tire bead as it does on the other two brands. That wouldn't be a big deal, except that this area isn't exactly black, either. It looks like crinkled black/white, which is the best that I can describe it. Another item is that it took a lot of weight to balance the tires, another visual issue. The texture of the whitewalls seems different than the other two, you have to rub a bit harder to clean them, not a big deal. So far, I like the Shinkos as the best of the three.
