Hey all, Well, I have ridden the bike harder than before on the Shinko tyres and after a few thousand km's have come to the conclusion that they are not for me. Now, this is my personal view. I have them on a GSX1400 which is not a light bike. I ride the bike agressively, but controlled and discovered a limiting factor to my riding style. They heat up quickly and then go off when too hot. The front feels as though they are rolling off of the rim when the tyres become hot. It is not a pressure issue as the pressure when warm was 36pounds. As a touring tyre, excellent, but not as a sport tyre for a heavier bike. Anyway, just a heads up.
