DETAILS

This 96mm big bore for your '15-Up 900 RZR or '13-Up Ranger 900 significantly increases horsepower and torque! We take the stock 900 cylinder and precision bore and nikasil plate it to our spec. We then send you with 2 high performance forged pistons, all rings circlips and wristpins. It also includes a base gasket and head gasket. Choose from our specially designed head gasket making your motor a 10:1 compression ratio for turbo setups or the standard 12:1 pump gas setup. Cylinder exchange required. Produces 100+ HP to the crankshaft. Those are simply huge gains from the 74 HP RZR motor, and the 60 HP or 68 HP Ranger motor (depending on year). For even bigger gains go with our cams!



  • Included in base kit: Bored & Re-Nikasiled cylinder, two pistons, rings, circlips, wristpins, base gasket, and head gasket.

  • Recommended options for maximum power: BMP Custom Tunes Bully Dog GT, Stage 1 Clutch Kit, BMP Exhaust

  • For even more power: BMP High Performance Camshafts

  • You can find all of these items included in our Complete 935 Big Bore Kit (RZR Only)


  What to send: Cylinder only for this kit. If purchasing cams or port work we will also need the cams or head.
