Here's a link to an interesting article I came across.I've included a paragraph. http://lifeisaroad.com/stories/2004/10/ ... kSide.html
I'm still not convinced it's safe.
It's not my job, intent, or duty to convince you of anything...especially the safety of motorcycle riding. But consider this: I ride, and ride hard. In the first 16,000 miles I had shredded 5 different motorcycle tires off the back of this machine...FIVE times I had to get this machine to a stop from high speed with a flat, shredded, or unseated tire and limited handling capability. These were not cheap or off-brand tires! Since I switched the rear to the Darkside, that's 100,000 miles now, I've had two rear flats...and both of those were ridable to get it home and/or the tire store to get it patched. Neither unseated or caused me any handling difficulty...it just felt wierd enough to get my attention. So, define safe?
