CG125 motorcycle camshaft gear, the number of teeth, installation hole position and CG125 camshaft, crankshaft gear completely match, directly replace the gear, no need to adjust the air phase; Tooth shape by CNC precision machining, and crankshaft gear meshing gap is small, no virtual transmission, to ensure that the valve opening and closing time is accurate; Using high hardness steel stamping molding, tooth surface abrasion resistance is strong, long-term operation is not easy to appear tooth wear, deformation; Align the camshaft installation position and fix it with bolts. After installation, only check the valve timing to use.
