I have been through dozens of MT21's and can't argue with this. I get frustrated with how fast they wear on my 640. Not so much on my old XT350. They lasted a couple of thousand miles on it. But everytime I try something else I always go back to the MT21 for the next one.
For the size tire that 250 runs have you considered a Michelin AC10? Pretty sure those come in 110 and 120 x18. It is probably more aggressive than an MT21 but still does OK on the street. They have held up well on my MXC200.
