Muzzys RZR XP Big Bore Kit

Even though the stock engine in the Polaris Ranger RZR XP 900 is wickedly fast, some people just want to go faster. Fortunately Muzzys has stepped up with a big bore kit to please the go-fast crowd.

“The Muzzy 995cc billet aluminum big bore kit for the XP 900 is at the top of the field in terms of performance, quality and overall value, Muzzys says in a release.

The precision machined billet cylinder features a closed deck designed for improved cylinder rigidity and better head gasket sealing. The design also incorporates larger water jackets for better cooling.

The kit includes a nickel silicon carbide coated billet aluminum cylinder, two 99mm slipper type racing pistons, rings, pins, clips, head and base gaskets. The kit retails for $1,799.95. Muzzys recommends the Muzzy cams ($465.95) and valve spring kits ($410.95) for use with the big bore kit.

These kits are currently in production. Pre-orders are being taken now. Click here for more information.
