Wear out too quickly and defects
These came with my new 2018 KTM Duke 390, the rear tire showed belts on the first season i used them at maybe a bit over 5000km, in the middle of a trip when i was in Gaspe, i was not happy. Changed it for a Bridgestone Batllax.
2nd season on the front and they are finished now. The front is also showing some weird bulges in areas (defect?) but the wear pattern overal looks even althouh tread is near finished.
Also i always checked pressure levels as i do a lot of touring and wanted these tires to last but they simply do not. I have no idea how they get so many good reviews, but for me these were teriible! Maybe there's a difference with the ones that come from a OEM with the bike vs the ones you buy, don't know.
Bottom line, they do offer grip but last a ridiculous short amount of time, i will never buy a set of Metzeler because of this and can not recommend them.
