Belt Life

I am going to replace my 2010 Honda and was thinking about the 2016 Grizzly EPS SE. My question is about the belt drive, how long may it be until I would have to change a drive belt. I am retired so my riding is not aggressive. I have a couple of friends that just bought the new Honda’s and they are having problems with the shifting on these 2016 so I am seriously considering the Yamaha. I realize no belts would be changed yet on the 2016 model but in your past experience what amount of miles would one expect to get on a belt.
