On tarmac that's true, off road it's pretty swift!
When I first tried an XT, I was suprised at how stable it was on the road (up to about 80 mph, on dual purpose tyres, as a first impression). I was expecting a bit of nervousness at speed. I've since changed to knobblies, at normal pressures, as I wanted the off road performance, and over 60 mph on the road it's a lot vaguer now, and does weave a bit.
I upped the pressures for a 60 mile 2 up road trip, and it was ok still. (At very sensible speeds)
The other half blagged a lift home, allowing me to blast the 60 miles home 1 up, without dropping the pressures, and even on the knobblies the handling was much improved.
A weave is usualy indicative of softness on the suspension and / or tyres.
I had a 350 YPVS way back when, which had oversize tyres fitted, which weaved horribly cranked over at 80+. Going back to standard tyre sizes, and upping the preload on the rear shock cured that problem (but not the tank slappers!)
If you are on the generous side, this will make the softness symptons worse.
It's pretty hard to test the shock, without replacing it, but after the tyre pressures / sizes, that's where I would spend my money.
A steering damper is to absorb rapid oscilation, as in a tank slapper, I don't think it will stop a weave. That would be my last resort.
