Review WISECO Series Forged Piston Kit

Introducing the WiseCo K650M89 Forged Piston Kit, a high-performance upgrade for your motorcycle engine. This piston kit is meticulously crafted from forged 2618-T6 aluminum alloy, ensuring superior strength and durability compared to its cast counterparts.

The WiseCo K650M89 pistons are designed with a dish shape that optimizes the combustion chamber volume for enhanced power output. Each piston features a low-friction skirt coating that reduces reciprocating weight and minimizes wear and tear on the piston rings. The piston tops are CNC machined to exacting specifications, ensuring pinpoint accuracy and a perfect fit in the cylinder bore.

The piston kit includes forged piston pins made from SAE 4340 steel. These pins are heat-treated to increase their tensile strength and are precision machined to ensure a snug fit in the piston. The piston pins are also coated with a high-performance, low-friction material that reduces friction and minimizes wear.

The compression ring is designed to seal the combustion chamber and ensure maximum compression. The oil control ring helps prevent oil from leaking past the piston rings and into the crankcase. The top ring seals the combustion chamber from the crankcase and ensures proper compression.

This piston kit is suitable for high-performance applications and is recommended for motorcycles that see heavy use or high-rpm operation. It is important to note that installing this piston kit requires a significant amount of mechanical expertise, and it is recommended that the installation be performed by a professional mechanic.
