27 Big Horns on mine. The belt life should still be around 8,000 miles and with clean air the grease will stay clean enough. This will be a very fast UTV on the tight trails with the speeds under 50. Also a very good rock crawler. The high speed guys really need the super long 4 seater wheelbase for the speeds above 50 but those $22,000 + UTV's won't do well on the tight trails. I'm too old for the super fast stuff and there is a lot of fun to be had by backing it in on the 10 to 15 mph corners and keeping it sideways half way down the straight before backing it in on the next corner. We have lots of truck trail and sand wash for this kind of riding. Its a lot safer at speeds under 50 too. I will remove the sway bar for better suspension and install alloy wheels with more off set.
