Interestingly, my local scooter shop Scooterville in Minneapolis had them in stock and were happy to put them on for me, and NOT revzilla/Cycle Gear/any of the larger box stores that advertise their stock online.
Perhaps exacerbating this issue, these have also become the tire of choice for the Honda Grom/Monkey series and it's clones, as they have the same size wheel.
I DID pay a decent premium, but I ran my original Kenda flat at 4100 Miles, shortly after posting this, so it was time.
