Specifications

Includes

• (4) Pistons
• Pins PN # S424

Features

• Valve Pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized
• Piston Crown shapes designed to promote maximum Intake Charge efficiency through scavenging mixture "Cross Flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower
• Piston Domes designed for optimal quench during the compression/combustion cycle, resulting in resistance to detonation and preignition
• The end result is longer engine life and increased horsepower potential
• Precision machined ring grooves with proper orifice/accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal and minimized blow-by and oil consumption
• World class, ISO Certified, forging facility that utilizes the latest technologies - Featuring complex forged shapes, advanced materials, and feature-aligned grain flow technology
• Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in the bore for optimum ring seal

Wiseco® began the manufacture of pistons 70 years ago when founder Clyde Wiseman started making them in his garage. The pistons he made at that time were destined for use in big bore marine engines, and like so many successful companies that began in people’s garages, word of what he was doing spread and soon he was making pistons for friends and so business began to grow. When Wiseco was officially formed in 1941 it serviced the needs of racers and powersports enthusiasts, and today the powersports sector – predominantly motorcycles and ATVs – now accounts for the largest portion of the work done by the business.
