Polaris gearing chart

Hi,

does anybody know of a gearing chart for the pro ride, showing gear ratios, top speed and required chain length?

I'm trying to find what gears I need to make an rmk do 90 miles an hour top speed. (Changjng track out for a 2" or shorter)

Pretty sure that about what a stock 2011-2015 will do with the 2.1 gearing it has from the factory.

Ok. I want be able to comfortable run 60-70 mph on lakes.

My 2012 XP 154 was geared to do 80 top speed stock. And it rev'd very high at 60 mph. I actually found gearing up increased acceleration, at the expensive of blowing more belts

If you are at lower elevation, I would run something around 1.9 to 2.0. I would gear it at 2.0 It would give you 100mph potential and not so high to cause belt issues.

What does 2.0 mean?

top gear to bottom gear ratio, like 21 tooth top gear 42 tooth bottom gear
