Has anyone ran smaller tires on their 250ex?? I currently am trying 21-20's..instead of the 22's all the way around. I race hare scrambles and it is really difficult in turns with the 22's...these little quads are so "tippy"! I do have a lot more stability but it most definitely is a rougher ride. Just wondering if anyone has done this and if so any trouble with clearance in the ruts, etc,?? Thanks!
