The first 4wheeler I bought was a Polaris 500 Sportsman. My daughter (started at 13) rides it and has even ridden it up some very gnarly trails. I love bikes and especially single track trails that quads can't ruin. But I found out quads have a lot of advantages too,, like hauling lots of stuff. But they do roll and in an open spot they don't stop for a long time,, I totaled an 800 Sptsmn first ride out,,insured luckily. So I have had an 800 Sptsmn, and just bought the 850 XP Sptsmn,, it's sweet. Good luck
