Pro Circuit High Compression Piston

• Product Details

  Important Note:

  This piston is for a stock sized bore. Please measure your cylinder to check clearance before ordering.

  By using a Pro Circuit high-compression piston you will gain both low-end torque and top-end power. High-compression pistons work equally well on stock or modified motors with the same results, more power at every RPM.

  • Pro Circuit developed their High Compression Piston with the intentions of satisfying the need of your motorcycle's thirst for more power.
  • An exclusive motorcycle engine upgrade that has the ability to boost low-end torque without neglecting top-end power.
  • Increases overall power whether you are running with a stock or modified head making this an easy way to step up your bike to a whole new level.
  • The power gain does not have to come with the price of expensive race fuel; the piston works with premium pump gas.
  • Includes a high compression piston, rings, (coated or un-coated) wrist pin, and circlips.
