Thanks. Well I can't say much about them cause they have only 4.5mm tread at rear and 6mm in front and bought this bike last month. I used mitas e09 front before on my xt600E and it was great unless I went into wet muddy roads(But I think only full knob tire would have grip there).
But I will get new Mitas e09 rear next month for sure. Same tread as t63, but 25� cheaper.
However I drove in sand couple of days ago and they did ok and didn't get stuck in sand. Even if the center was pretty worn. Was suprised
