The Renthal 191U-428-50GESI UltraLight Rear Chainwheel is engineered for high-performance powersports applications. CNC machined from durable 7075 T6 aluminum, this sprocket offers a significant weight reduction—approximately 66% lighter than traditional steel counterparts—without compromising strength or durability. Designed with precision, it ensures a perfect fit, excellent concentricity, and optimal load dispersion, thanks to computer-optimized tooth profiling that maximizes power transfer to your rear wheel. This advanced manufacturing process results in a lightweight, high-strength component ideal for racing and aggressive riding scenarios. The hardwearing surface treatments extend the sprocket’s lifespan, making it a reliable choice for demanding use on Kawasaki KLX140 models from 2008 through 2013. Featuring a groove design, it enhances chain engagement and reduces wear, contributing to smoother operation and increased drivetrain efficiency. Whether you’re upgrading your stock setup or building a race-ready machine, this sprocket delivers superior performance and durability. It is compatible with a range of Kawasaki KLX140 and KLX140L models, making it a versatile upgrade for riders seeking to improve their bike’s power transfer and overall handling.
