Thanks for your thoughts/findings, Bob. I was running a Yokohama Avid Envigor on my Valk Interstate and loved it. I was long past my warranty period when I installed it however so that was no issue. Now that I have a brand new B..I want to go Darkside again, probably with the Michelin Alpin as soon as the B's rear tire wears out.
I've yet to hear of anyone ever crashing due to the fault of a Darkside tire. I have heard of many that have crashed when their MC tire suddenly went flat(in some cases due to the OEM valve stem giving out).
Thanks!
