• Crowns in C45T - hardened and tempered steel - are high-end products from PBR SPROCKETS for sport bikes, roadsters, and touring motorcycles, developed in collaboration with MotoGP and Superbike teams.
• To ensure the highest level of quality, C45T crowns are CNC machined and undergo a hardening and tempering treatment by induction on the teeth area, to guarantee the greatest resistance on the part in contact with the chain. The end result is a very robust piece, extremely reliable with longer durability and higher performance over long distances.
