the only thing with the HD is that the front in 2" bigger then the back

 

Do you have to go with ITP? The original Razr is a great tire, pretty capable for trail riding and such. Great sliding characteristics too. I like having the rear tires be a touch smaller than the fronts. I've ridden a few that had either similar or larger sized tires front and rear and the handling felt "off."

 

thanks everyone i've decided that i'm gonna try thr XCR in front 21-7-10 rear 20-11-9
