Renthal UltraLight 520-43T Hard-Anodized Rear Sprocket for Honda CBR1000RR

Renthal UltraLight Rear Chainwheels are CNC machined from 7075 T6 aluminum to extremely tight tolerances, 66% lighter than steel. Computer engineered and tested to ensure a precise fitment, concentricity and load dispersion with tooth profiling to provide maximum power transfer. A combination of high strength base material, cutting edge manufacturing methods and exceptional hardwearing surface treatments its clear to see why Renthal's light weight all aluminum rear sprockets can be found on the rear wheels of many factory race team machines.

Upgrade your motorcycle’s final-drive performance with the Renthal UltraLight rear sprocket, part number REN411U-520-43P-HA. Designed for Honda CBR1000RR applications, this 43-tooth rear sprocket is CNC machined from high-strength 7075-T6 aluminum for an excellent balance of low weight, durability, and precise power transfer. Its lightweight construction is engineered to reduce unsprung and rotating mass compared with conventional steel sprockets.

Renthal computer-engineers and tests each sprocket to provide accurate fitment, consistent concentricity, and effective load dispersion across the drivetrain. Advanced tooth profiling helps maintain smooth chain engagement and supports efficient power delivery under demanding street or track conditions. A hard-anodized surface treatment improves resistance to wear, helping the sprocket maintain dependable performance over extended use when paired with a properly maintained 520 chain and front sprocket.

The Renthal UltraLight rear sprocket is designed for riders who want race-inspired construction without sacrificing practical fitment. It is compatible with 2004-2013 Honda CBR1000RR motorcycles listed below and is intended as a direct replacement for the application-specific rear sprocket.
