I'm shopping around for new tires for my '02 Ninja ZX6R, as I'll need them for the upcoming riding season. I've only used the OEM Dunlop 207's, and though I'm very happy with the wear, I'd like to try something different. My riding consists mainly of mountain and country back roads, no track riding, no interstate riding, and the occasional short commute to work. I'm an average street rider, not overly aggressive, but do have occasional "spirited" moments. The Ninja runs that odd 65 series front tire, and not too many manufacturers make that size. Can I run a 70, or will major adjustments need to be made to run that size? With that said, I've been considering the Metzeler Sportec M-1's. The only thing that concerns me is I've read that they wear out quickly. Would they be that bad for someone like me with an average riding style? What tires would you consider? Thanks for your input.
