I found out that if I run Non Hayabusa specific tires on my'04, the fronts wear faster than the rears. Been running Stradas and now need both tires. Not sure what I will try next, as I do a lot of touring and I live about 25 miles from the gap. Front end load seems to be worse for wear on the non-spec tires, in my experience. I've never got more than 5k out of any rear tire and I'm not that agressive on aceleration, but can be in the twisties. The stradas I was replacing 2 fronts to 1 rear and if I ran 40 PSI or less. I usually run 40-42 PSI and it does fine. My suspension is set to the stock neutral settings, so I have not done much ther, yet.
