pirelli MT60 on a X

Has anyone tried these?

I have a WR250X in Colorado with dirt tires and love it. I live part time in Costa Rica and I found a really nice WR250X for sale down here with street tires. Where I live in Costa Rica are some really rough dirt roads, so the street tires would have to go. I did find a vendor in San Jose that can get the Pirelli MT60. It looks like it would be a very good tire for my needs.
Looks like the tire sizes of the MT60 are 120 and 130mm widths. I pretty sure they would fit ok. I know I put a 120 MT21 (on the front wheel) on my X back in the states and had a little rubbing on the fork, but I just trimmed some of the side knobs a bit.

I had MT60s on my KTM SMC.

While they were great on the street, they, as any multi-purpose tire may be, were limited on dirt.

Accelerating wasn't the problem (the SMC spun everything on the back), although they lacked traction, but STOPPING was a calculated risk at best.

As long as you don't expect more stopping traction than you have (terrain/surface permitting) you'd be okay.

I think I need to see if the Pirelli disrtibutor down here can get hold of a set of MT21"s.
