I ran two Shinkos about a decade ago, I got a 70/30 and a full street one (can't remember the model for my supermoto. The 70/30 was complete garbage. In anything wet it was like jelly and offroad it tore up even in light dirt/gravel very quickly. When I changed over to my street rim/tire it was more of the same but super fun. The ass end could slide out easier and getting the rear to spin was a lot easier. It had grip but on a light bike it was far less then the Supercorsas I had put on when I bought the bike.
