Polaris RZR 170 Cylinder Kit 63mm Upgrade
Bolt hole spacing at 80.5mm, standard GY6 150 is 78.5mm...there is some confusion since 61mm and 63mm kits are labels 170 and 180cc
There is a few kits out there so be careful, this one is made just for the Polairs model RZR 170.
There is a head to match plus cams will work from NCY. Carbs should be upgraded from the 21mm stock carb to 24mm up to 30mm
