Renthal 520-16P Front Chainwheel for BMW S1000R, S1000RR (2019-2023), S1000XR - Ultralight Performance Part

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

The Renthal 520-16P front chainwheel is engineered for high-performance motocross and supercross applications, offering a perfect blend of strength, durability, and lightweight design. Crafted from a specially developed nickel-chrome-molybdenum steel alloy, this chainwheel is case hardened and core refined to maximize hardness and longevity. Renthal's in-house CNC machining ensures each component is manufactured to the tightest tolerances, providing precise fitment and optimal performance. The surface is hardened through a controlled heat treatment process, extending service life even under demanding conditions. This ultralight chainwheel reduces rotational mass, which enhances engine responsiveness, accelerates spin-up, and shortens over-run, translating into quicker acceleration and improved handling on the track. Used by many factory motocross teams, the Renthal front chainwheel is a trusted choice for riders seeking top-tier performance. Its design also reduces overall machine weight, contributing to better power-to-weight ratio and agility. Whether you're upgrading your BMW S1000R, S1000RR (2019-2023), or S1000XR, this durable and lightweight chainwheel provides a vital upgrade to optimize drivetrain efficiency and race-day performance.
