Polaris 90 Outlaw Piston Kit - Wiseco - Forged Series, 10.5:1 CR, 47.00 mm Bore - `07-`14. A direct-replacement forged piston kit engineered for the Polaris Outlaw/Sportsman 90 models from 2007–2014, providing a complete package ready for installation.

This Wiseco Forged Series piston is built for riders who modify or maintain small-displacement ATVs and UTVs. The kit includes the piston, wrist pin, rings, and circlips, so you have everything required to complete a rebuild. Forged construction offers higher material strength compared with cast pistons, improving durability under frequent load and higher RPM use. The 47.00 mm bore and 10.5:1 compression ratio match the specified fitment for the Outlaw/Sportsman 90, and components are precision machined for proper clearance and fit.
