16447-88 High Quality Replacement Cylinders for Evolution Models

These Evolution Sportster cylinders are engineered for maximum durability and cooling efficiency. They feature high-density, centrifugal cast ductile steel liners that are cast directly into the aluminum cylinder body. This cast-in design provides much better heat dissipation than pressed-in liners, which means your engine runs cooler even under heavy loads. To allow for precise piston fitting, these cylinders are honed a few thousandths undersize, giving you the ability to set the exact tolerances your build requires. Sold each, these cylinders fit Sportster and Tube frame models and are a high-quality replacement for OEM 16447-88.
