Renthal TwinRing 49T Rear Sprocket 1120‑520‑49GPS – Kawasaki KX KXF KLX / Suzuki RMZ 250/450

The Renthal TwinRing 1120‑520‑49GPS is one of the most advanced and durable off‑road sprockets ever produced. Developed over five years of engineering and race testing, the TwinRing combines a 7075‑T6 Ultralight aluminium inner ring with a hardened electroless‑nickel‑coated steel outer ring, creating a sprocket that lasts up to 3× longer than standard aluminium sprockets.

The TwinRing’s unique flat‑face profile keeps weight to a minimum while maintaining the same width as a standard sprocket. The outer ring is expanded to 200°C and permanently bonded to the inner ring during assembly, ensuring unmatched strength and reliability under extreme racing conditions.

Trusted by the world’s fastest riders — Ryan Dungey, Eli Tomac, Jeffrey Herlings, Antonio Cairoli, and countless factory teams — Renthal is the number‑one choice for championship‑winning sprocket technology.

This sprocket is highly favored for racing due to its durability and weight reduction, often used with a 520 Pitch Motocross chain.
