I wouldnt own anything except honda. Been stranded 14 miles into the woods by an artic cat with a roughly 200lb deer and a few hogs before, and it had less than 20 hours on it.
I live in the mountains and farm land and am around all makes and models of atv and utv's, and honda and polaris are the best for reliability for sure. Id much rather have a utv though than an atv.
if you want reliability go with Honda...I have had two honda's 1 2000 300ex and a what i like to call my mostly stock 05 trx545r
my mom and dad have the big ute quads a Foreman and a rancher, my brother has a foreman as well ans his son has a trx90
