Wiseco's Pro-Lite forged pistons are the result of decades of experience in 2-stroke performance, offering great reliability and performance across all-purpose and competitive riding. Each piston is forged — not cast — using aerospace alloy, with the molecular compression of the forging process delivering superior tensile strength, fatigue resistance, and material ductility compared to OEM cast components. All forging and machining is performed in-house at Wiseco's facility in Mentor, Ohio, USA.
