YBR125 motorcycle disc, five hole mounting position and 06 YBR125 front wheel fully match, directly replace the original disc brake without adjusting the mounting bracket; The disk is equipped with double heat dissipation holes (inner ring big hole + outer ring small hole), which can quickly dissipate heat during braking to avoid deformation of brake disc at high temperature and thermal decline of brake pads; Made of hardened stainless steel, disc surface hardness, wear resistance, suitable for frequent braking riding conditions, prolong the service life of the brake disc; The flatness error of the disk is very small, and the brake pad is closely fitted, and there is no jitter and abnormal noise during braking, so as to ensure the linear and stable brake touch; The surface is treated with anti-rust technology, suitable for rainy days, wet environment riding, reduce the decline of braking effect caused by disc rust.
