YBR125 motorcycle side support spring, total length of 135MM, hook size and YBR125 side support support/frame interface completely match, directly replace the original spring, no need to adjust the installation position; Made of 65Mn manganese steel, the surface is galvanized to prevent rust, elastic and durable to resist fatigue, suitable for frequent opening and closing of edge support; The elastic parameters are standard to the original factory, and the strength of the side support is moderate when it is retracted/unfolded, which not only saves effort but also ensures the stability of parking; It can be mounted on the hook position of the side support and the frame, without additional adjustment of elasticity or Angle; The spring steel material has good deformation resistance, and its elasticity does not decrease after long-term use, thus reducing the replacement frequency.
