I put on a Pirelli scorpion mx extra 120/100/18 to test. The hook up is not as good as the 130 IRC but the
wear after one ride of hard pack including severe jagged rock was impressive. It only rounded off a little of the
edge. Looks like a long lasting durable low cost tire.
Im still a fan of the M5B but for certain conditions I might stick with this one.
The 120 M5B was a little small and after wearing down some did chunck pretty good on jagged rock.
It is a soft terrain tire though. The 130 faired better. Got to love the M5B traction though
For the front as I mentioned before, the Pirelli scorpion pro is a favorite. But it wears a little too fast for me
and develops that flat top look too early.
I like the Michelin desert front that I have on now better. This tire does not wear out half as fast as the scorpion pro. And even though deep sand traction may not be as good , everywhere else is great. And because of the rating of this tire and the construction (also DOT) I don't worry about pinch flats and high speed stability is great.
Its expensive but worth every penny.
I will try the Pirelli scorpion xc ms after this tire to test. I have heard good things that I would like to confirm for myself.
The bridgestone 403/404 combo are my tires for motocross but not for dual sport and extreem off road conditions
