Anyone know anything on this swingarm????

im running a 150 70 18 on my rear. I wouldnt go any futher.

Ya i was wanting something a little wider but not so much where it becomes a hassle to ride.

Think it would be good idea to have it widened a 10 1/4? If i had to replace the pivot tube anyways it wouldnt be much to widen it? I could just get a new cross bar andmake new plate gussets?
