TITANIUM valves require the use of KPMI Nickel Aluminum Bronze valve seat inserts. Developing KPMI’s premium nickel aluminum bronze alloy valve seats, required a two year R&D commitment. During the course of our research we recorded and verified results with; 4&5 valve singles, domestic and foreign sport compacts, multi-valve and cylinder street bikes as well as British and European 4 Strokes. In every one of our tests the machinability, wear, and thermal-conductivity, surpassed our standard set for success. Given the results of our testing KPMI then developed a production range of seat inserts that could be used for most applications. If the sizes you need are not listed then call and we will custom build seats to your specifications.
