What's the E mean? I went to buy my tires and I seen this E at the end of one of the options. Can someone elaborate?
Metzeler had more Spec Z6 tires then I could understand. Some for BMW some for the FJR but I'm not sure if they were any different in make up or structure then you'd buy off the rack at some moto store?? BT-016/014 are are another OEM spec tire for the super sport bikes that you can also buy off the shelf too.EDIT- so if it's for the OEM spec, does that mean there's 2 different BT021 rear tires made differently between the E and non E?
