I recently purchased Riken Raptor VR tires for my 2000 GSR. Originally I had Dunlop SP sport ultra high performance summer tires (which didn't last long but handled great). The Riken's were recommended by a big 10 tires guy over what I had originally ha come to buy, Yoko AVS ES100's. He said the Riken's would last longer, perform just as well, and were cheaper. So I went with the Riken's even tho I have never heard of them. The Riken's are all season UHP tires and the dunlops were summer UHP tires. Should I be feeling any difference in handiling? The Riken's are louder and seem to not handle the road as well. Did I just buy some shit tires or do they just need some breaking in/alignment? Any feedback is greatly appreciated. Thanks
