I've got a 1980 XS650, the one with the tubeless rims, and I'll be needing a new front tire for next year. I'm looking at a number of 100/90-19 tires; naturally I want a good deal, but I want a tire rated over 100 MPH (though I seldom go there) and I want a good balance of traction and lifespan. Right now, I'm looking specifically at the Kenda K673 Kruz and K657 Challenger and the Shinko 712 and 777. Does anyone have experience with these tires that they'd like to share? Which is the better option? Or is there one I should be looking at that I've missed?
