Supersprox Rear Steel Sprocket 48 Tooth Black Compatible With KTM 125 XC 2021

Supersprox goes all out with their Rear Steel Sprockets, from first stage to last. Let's start with the first. Supersprox begins by using a highly specialized SCM435 Ni-Chrome-Molybdenum low-corrosion type steel as the base material for the sprocket. Once the shape has been CNC machined, the sprocket is case hardened to give it a low carbon core and an incredibly tough surface hardness. To finish it off Supersprox uses hot-dip galvanizing to protect the surface of the sprocket by chemically creating a shielding layer of zinc carbonate.
