Our Front chain-wheels feature a specially developed nickel-chrome-molybdenum steel which is case hardened and core refined to give the ultimate combination of strength and hardness. Ultralight chain wheels, Renthal have taken extra time to machine away surplus mass to reduce the mass of the chain-wheel. Chain-wheel mass reduction offers a two-fold gain. The overall mass of the machine is slightly reduced and the rotating mass of the gearbox is reduced, allowing faster engine spin-up and shorter over-run.
