You can't go wrong with Michelin X-Lite. It's 500grams lighter than the existing X11. Nice soft side walls, grips very well.
I've only tried a Dunlop D803 on the rear once. It was OK but I much prefer the Michelin even the older X11 is a great tire.
I have a new Mitas ET-01 TL Trials. I'm thinking on trying on my EC300 next.
Cheap tire stiffer side walls OK for and enduro, it's just a little to wet and snowy right now.
