Introducing the WiseCo K2787 Pistons, specifically designed for Harley-Davidson engines with a bore size of 4.250 inches and a stroke length of 11.0 inches. These high-performance pistons are engineered to deliver superior power and reliability for Harley-Davidson V-Twin engines.

The WiseCo K2787 pistons are crafted using a forged aluminum alloy material, which ensures a strong and durable piston that can withstand the rigors of high-performance riding. The piston skirts are designed with an optimized profile that reduces friction and improves ring seal, which in turn enhances engine efficiency and reduces wear and tear. The piston crowns are designed with a dish shape that provides improved combustion efficiency, resulting in increased power output.

The piston rings are made from a high-quality, heat-treated steel material that ensures a tight seal and reduces the risk of piston slap. The rings are also designed with a nitrided surface treatment that enhances their durability and extends their service life. The piston rings are also fitted with a chamfered edge, which makes the installation process easier and smoother.

The piston pins are made from a high-strength, heat-treated steel material that provides excellent strength and durability. The piston pins are also fitted with a phosphate coating that prevents corrosion and reduces the risk of galling. The piston pin bore is also chamfered for easy installation.

The WiseCo K2787 pistons come with a piston pin retainer made from a high-strength, heat-treated steel material. The retainer is designed to provide excellent retaining force and prevent piston pin movement during high-performance riding.

These pistons come with piston rings, piston pin, and a piston pin retainer. They are designed to meet or exceed OEM specifications and are ideal for Harley-Davidson V-Twin engines that require high-performance pistons for increased power output and reliability.
