I needed a replacement for my 2004 ZX6R and I didn't want to just give my money away for tires that I could get cheaper and just as good. There are very few reviews for Shinko but I did my research and they sounded good enough and my mechanic assured me that they were good tires. He even had them on his GSX-R1000 and was going to continue to use them. With his vote I went ahead and bought them and they are great tires . Excellent grip wet or dry and they really seem to be wearing well. These will be my next set as well.
