In a pure sport model the 5 speed makes sense. It's a motorcycle setup..
1. More efficient, 15-20hp more to the ground verses the cvt..
2. You can better use the power you have
3. The clutch allows you to vary the power to the ground.
On a hill climb you'd likely pick 2, or 3rd and go right on up.. No problem..
I can say for the riding I do the wolverine is easier with the auto. I could see maybe getting one as a second rig, but to be honest unless you are near a track, open plains, or desert.. The yzx is extreme over kill.. But I'd like to get one on a track!
In the conditions it's intend for it will likely obliterate the rzr and mav.. Depends on actually hp.. Of course
