In any other environment than Sand Dunes... and maybe Hunting big game or something... I see no good reason to bother with those destroyers of terrain.
Not only that though... I noticed that quads have this unique thing of being able to shake their heads in a side-to-side rotational kinda way (because of two points of contact out front) which can seriously aggravate shoulder bursitis from previous injuries in a fierce way!
They are fun to powerslide in the dunes with... but I'd much rather be able to jump the long distances and haul the kinda ass that you can only do on a regular (500cc two-stroke) dirtbike out they're.
