Renthal Rear Twinring Sprocket 520-48T Black Fits 91-24 KTM 125-525

Description

The Renthal Twinring Rear Sprocket is designed for KTM 125-525 EXC, SX, SX-F, XC, XC-W, and XC-F models. It features a dual-material construction with a high-strength 7075 T-6 aluminum inner ring and a hardened steel outer ring, ensuring durability while keeping weight to a minimum. The outer ring is electro-less nickel coated for enhanced wear resistance and is permanently bonded to the inner ring through an interference fit at 200°C. This sprocket is engineered for longevity, lasting three times longer than standard aluminum sprockets while remaining significantly lighter than all-steel alternatives. It includes flat socket head screws for added strength and self-cleaning mud grooves to prevent dirt buildup, reducing wear and maintaining performance. The Renthal Twinring offers a balance of durability and lightweight design, making it an ideal choice for off-road and enduro riders looking to minimize maintenance while maximizing ride time.
