I went for the XTR mainly being lighter & carrying it's
weight lower... less destructable...
By the time yer fuel the XTZ add a bit of gear you
have near a 1/4 tonne dirt bike to toss around..
The XTR is not a lot lighter but it carrys it's weight
lower so it dose feel a lot lighter than the 30 odd kgs..
Yamaha make a good high screen for the XTR..
