Our black anodised highest quality aluminium hybrid 428/116 sprockets are multifunctional. They can be mounted as 1 pcs. solid or as split into 2 halves. The solid sprockets have a carefully chosen split section which enable the spockets to be split into 2 halves by hand. The split section location is exactly in between 2 teeth. (the tooth itself is never cut). The manufacturing procedure ensures no material deformation. The GOLDSPEED 428/116 hybrid sprockets are used for 4-stroke karting / rental karting / rotary engines karting. Their internal diameter is 116MM so they fit most used sprocket carriers. GOLDSPEED 428 hybrid sprockets are proudly made in The Netherlands!
