Renthal front chain-wheels are simply the finest front chain-wheel on the market today. 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. Renthal took extra time to reduce and machine away surplus mass of the Ultralight chain wheels. 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. Renthal's ultralight chainwheel is used by more factory motocross and suprecross team than any other chainwheel.
- Renthal's in house CNC facilities accurately machine each individual front chainwheel to the tightest tolerance possible
- Each chainwheel is introduced to great heat that hardens the surface to ensure the longest service life possible
- The strength and hardness comes from the core refined 655M13 Nickel-Chrome-Molybdenum alloy steel
- The ultralight design reduces weight to maximize performance
