OK so I'm trying to buy a machine and after reading every SXS forum ( Honda, RZR, CAN AM ) - it has basically scared the crap out of me - I know for every bad report there are 10 guys out enjoying them no problem, But hey it's a lot of money .. So with that one last question. I intend to do a Colorado trip yearly. I want to explore most if not all the jeep trail type passes.. ie Engineer, Corkscrew, etc.. ) - Will this machine perform well at high altitude? Does it have adequate engine/transmission braking for these types of trails? Of note - while I was in Colorado last month 2 died in a RZR near me when ( according to the reports I heard) their belt broke and they tried to coast down Corksrew and lost their brakes..Sad deal for sure. Def got me thinking about downhill desent control.
