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.
The Renthal UltraLight Rear Chainwheel is engineered for high-performance powersports applications, specifically designed to fit KTM 85SX, Husqvarna TC85, and GasGas MC85 models from 2007 to 2023. Crafted from CNC-machined 7075 T6 aluminum, this sprocket offers a significant reduction in weight—approximately 66% lighter than traditional steel counterparts—without compromising strength or durability. The precision manufacturing process ensures a perfect fit, with tight tolerances and optimal concentricity, promoting efficient load distribution and maximum power transfer during aggressive riding. Its tooth profile is meticulously designed to optimize engagement with the chain, delivering reliable performance on and off the track.
