About This Product
Need some more grunt from your old Polaris 250?
Check out this Wiseco big bore kit.
It's a remanufactured cylinder and piston top-end kit, bumping your displacement up with a 73mm piston.
It's designed to fit a bunch of 250cc 2-stroke Polaris models from 1989 to 2006, including the Trail Boss, Big Boss, and Trailblazer.
The manufacturer part number is 3083769.
This isn't just a stock replacement—it's a performance upgrade to give that 2-stroke a bit more punch.
The item has been completely rebuilt to be functionally equivalent to a new part.
