Description

Wiseco leads the performance aftermarket by producing the highest quality forged pistons for Dirt Bikes, ATVs, Snowmobiles, Marine Vehicles, and Motorcycles right here in the USA. Wiseco is unique because we forge all of our pistons in-house, and produce all of our forge toolings right here in the USA. This allows us to control all aspects of our manufacturing process from raw bar to skirt coating finished parts. In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art technology such as new shapes, coatings, and components, and lead the industry through rigorous R&D. Linking all segments of Wiseco's organization through design, testing, manufacturing, and distribution allows us to fulfill market needs with minimum lead-times.

Brand Details

Wiseco™ started in 1940 on the East Side of Cleveland, Ohio when Clyde Wiseman began making pistons for himself and some of his friends. After almost a century in the business, Wiseco™ has been identified as a piston manufacturer, but they didn't stop there. Wiseco™ went on to making a plethora of innovative motorsports equipment from clutch covers to valve kits, including Wiseco High Performance GP Style Piston Kit 66.4mm STD, that will not have you questioning the quality or care that was put in to making them.
