This is my second one. The first one did 1200 miles from Green River to Sun Valley then another 1000 in various rides. I'm new to dirt, but if there is a better tire for a mix of road, sand, mud, and rocks then I'd be shocked. I'm 260 without gear and it held up very well under the weight, heat, and abuse. I felt it was solid on the road. I did the super thick tubes and ran about 20lbs and had no flats or issues.
Burned thru my first tire in about 5000 miles of rocks, roots, mud, and pavement. Off-road it performed just as I hoped, but I was really surprised how well it work on the road. They make noise and they vibrate some but that's what you get with a knobby tire.
This is on a Drz400s.
I used the MX51 for my enduro bikes for riding mainly in Michigan with great success . I installed these new MX52 replacements on my ARMHA MX bikes.
I'm sure that they will perform well like all of my Dunlops.
