I don't try to get too caught up in the horse power numbers. What I'm looking for is power to weight ratio and the power curve, where it makes it's power and for how long. This thing will be peppy and a lot of fun.Well its less then 57. I expect around 52 to 55, we will know in a few weeks. It looks like it will be enough for backing it in on some fast trail riding. Its about 50 pounds heavier then the 2 seat Pioneer 700 and about 250 pounds heavier then the Teryx 800. Its a little faster then the Teryx and way faster then the Pioneer. It should be a fun ride with outstanding suspension.
