The method used is testing the mechanical properties of several piston rings Supra X 125 which will be analyzed. The heat treatment process is carried out on the material of honda supra X motorcycle piston rings at temperatures below the melting point of 600 0C with 2 hour hold time and then cooled with oil and mineral water. Test results occur significant differences between piston rings Supra X 125 honda genuine parts and quality 1. The results of dimension measurement test shows the shape of the largest diameter is changed, dikomed form of the specimen itself which causes stretch when the heat treatment process. But the size of the thickness ring has not changed. While the results obtained in this study is 66,72 HRC ring piston roughness for Honda genuine parts and 63.66 HRC for quality 1 while the highest hardness price occurs in piston rings honda genuine parts with oil cooler 75,8 HRC.} }
