This whole set was mounted to Suzuki DR 125 SE 1996. First of all, the fit of these discs, spacers and springs is accurate and matching and when it comes to the quality of the material.the price for a set of 60zł for such a motorcycle is worth the installation only everything depends on how someone uses the clutch and with normal use it will last longer.
