Since 1939, KPMI® has taken great pride in our ability to design innovative performance improvements for valvetrains. This innovative ability has never been more apparent than with the development of the high-tech lightweight racing valve spring kits for the incredibly stressed and torturous environment in today’s V-Twin engines.
