BT021's are the biggest piece of **** that ever went into a tire mold. At 1000 miles on my new 10 the front is starting the feathering, cupping, scalloping, trapezoid, or what ever one want's to call it. They came on some BMW LT's too and all agree they are pure liquid **** in the shape of a tire.
Rant Off
I hate them! Wanted to get some miles out of them before my summer trip and put on the PR2's I have in reserve. I will continue to suffer through them for a bit longer but they are testing my patience and working on my last nerve. While the new front and rear suspension may have something to do with the wear as I push pretty hard, still they are worthless as a tire.
To the original OP I also find the FJR to turn in faster and with less bar input than I was used to, I pretty much think it a characteristic of the FJR and becomes pretty second nature.
Tire pressure as mentioned would be the first thing I checked and messed around with. I run 40/42 but you can mess around with PSI a couple of pounds either way to see if it helps. And I don't mean 30/32 or anything but 2-3 PSI either way wont hurt a thing.
