I second that I have a set of Razr2 22 in on my yfz and they destroy anything under neath them. I can be climbing some of the steepest hills in my area and If I stab the throttle it will try to wheelie while Im climbing in a heart beat. The strange thing is that even with all the hookup they have they still slide better than any other tire I have used.
For the record I still have an use amongst all my quads: Razr, razr2, kenda dominators, holeshot MxR6, Turf Tamers, IRazr, Duro Mud and Trail, Ams somethings, and all the dunlop stockers I have ever had. So if anyone wants an opinion on any of these shoot me a pm.
