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.
