Ya I have gone through genuine ones. Those made it about 25mi.
Knock off ones made it a block. Like seriously a block. I put genuine KTM springs in it instead of the washer stack. I was hoping for a little more longevity. I even tried to shim them out per KTM specs form the website but they are beyond fucked.
I contacted Puch shop and they said they are going to co tack HK and see if they are going to produce anymore.
I wanted to try the Tomar, but this thread has me worried it will be another waste of my time.
