I have a 2016 7000xt that now has 1100 miles on it. I've had a few teething issues with mine but nothing that would dissuade me from buying another one.
I had two issues. One with snowdust in my throttle mechanism. Cured buy purchasing the snow flare accessory for the footrests to the back of the tunnel. 60$!
2nd more recent issue is a lower coolant tube rubbing through causing a coolant leak. Arctic cat is aware of this issue and is taking steps to correct it on other models that are out in the market.
Beyond that it's been trouble free riding for 1100 miles. I'm happy with the fuel economy and even more happy with the machines capability. I'm convinced you can't get it stuck and it's got gobs of low end torque for towing stuff. The Yamaha engine provides smooth power and the team clutching is excellent for getting that power to your track. The WR3 transmission is also awesome. Any other questions?
