CG125 motorcycle starting bead suit, starting bead size, spring elasticity and CG125 starting system fully match, directly replace the original parts, compatible with starting plate, starting gear and other structures, without modification; The starting bead is made of high quality alloy steel, with high hardness and strong wear resistance, which can withstand the instant impact force during starting and avoid breakage or excessive wear. The fitting gap between the new starting bead and the spring is reasonable, which can eliminate the lag and abnormal sound during starting and improve the power transmission efficiency of the starting system. It is the core replacement component for start-up system faults (such as start-up skid and weakness) and is suitable for minor repair/maintenance scenarios of start-up system.
