You either believe the guys who simply come back with "mine doesn't" (and nothing else)...or you do your homework and ask yourself what the odds are that the story ends there (as many would apparently like you to believe).
A lot of us believed (well before others did the research) that the bean counters had finally left the engineers alone and allowed them to 'truly' redesign the entire driveline as it should have been from the very beginning.
The above is being pretty charitable to Polaris engineering. My '14 even with the metal sprague (vs plastic) and (I'm guessing) the shim in the right place isn't anywhere near right and never will be.
For this reason alone (not to mention the XPT differential's resemblance) I would be holding off for whatever Polaris comes up with next or the next best thing to come along from a company with a much better first year engineering record. For me, that would be largely CVT-adverse engineering such as has been practiced at Honda for decades, yet YMMV.
You also have to keep in mind exactly how that power enters the box in the first place which is often the entire story.
