YBR125 motorcycle clutch wood chip, inner diameter 91MM, outer diameter 119MM size and YBR125 clutch steel sheet fully match, directly replace the original friction sheet, no need to adjust the clutch clearance; It adopts the composite process of soaking formica fiber + resin, which has stable friction coefficient, high temperature resistance and abrasion resistance, and its life is twice that of common wood chips. Preset friction lines on the surface, can be used directly after installation without polishing, saving maintenance time; The stable friction coefficient ensures no power slip under high load conditions, and improves the smoothness of shifting and power output.
