Exactly...
To sum this though up...Every year Polaris engineers are aware of areas to improve.... and each year they work to improve the sled.
It generally will not result in a different part number or something that looks a lot different... but those changes are there like SRX said above.
The 2016 had a stellar year, IMO... especially putting into context that it was a first year for a new chassis/engine combo.
Plainly... every new year of a given chassis for Polaris Mtn. sleds brings a more evolved/refined product... that is good for everyone...but it doesn't make the previous year obsolete to purchase.
Lets face it... these things are expensive... if you can find a 2016 for a good price...and you have the money and the desire to ride your new sled yet this season... get it... they seem to have proven themselves in the hands of the consumer this season.... You can save some money and put a little into some areas, like the A-arms, adjusting your TPS to be dead on ...or tailoring your handlebar package to fit YOU well.
Ride em people!!!
I'm stuck with 70hr work weeks most of this season... but hey... I'm building a better life for myself (hopefully) .
.
Have you ridden at all this season?
