Just to note, the bike these are on is a WK SP125N. It is outright dangerous how little grip these tyres have. On a 10hp 125cc bike, the rear end would frequently break loose at random in poor weather, that is unacceptable. And then, even in dry perfect conditions, if you try and go at any pace that is above commuting speeds, the whole front end feels like it is going to try and kill you at any moment. They also handle terribly, they do not want to tip over. Even on a mega light bike it feels like I really have to tell it what to do to get it to lean over what so ever.
