Renthal Front Sprockets Renthal€š Road/ Street Front Chainwheels are CNC machined from 655M13 nickel chromium steel, cased hardened and core refined for durability. To account for the extremely high tolerances required for engine components, here at Renthal we make use of our in house CNC facilities to accurately machine each individual front chainwheel to the tightest tolerance possible. The case hardening process ensures that the front chainwheel has the longest service life possible. Each chainwheel is introduced to great heat that hardens the surface. Core refined 655M13 Nickel-Chrome-Molybdenum alloy steel gives the ultimate combination of strength and hardness. As used by the Kawasaki World Superbike team. 2013, 2015, 2016, 2017 and 2018 World Superbike championship winning chainwheels.
