At DMG Motorsports, we present the Vortex F5 Rear Sprocket 45T-525 in Black Hardcoat (part number 526K-45) — a race-proven, lightweight replacement sprocket engineered for compatible Suzuki and Triumph models running a 525 chain pitch. Vortex is a trusted name in the paddock, and the F5 line delivers the strength, precision, and durability that serious riders demand without adding unnecessary rotating mass to your drivetrain.

Every F5 sprocket is 100% CNC-machined from a specially formulated 7075 aluminum alloy, then hard anodized and finished with a PTFE black hardcoat for a look that performs as good as it looks. This process not only gives the sprocket its aggressive jet-black finish but also increases wear resistance, improves lubricity, and helps the sprocket stay cleaner and run longer between chain services. Vortex's patented tooth profile is unlike any standard OEM design, contributing to smoother power transfer and extended sprocket life, which is why Vortex sprockets have earned a reputation as being trusted by champions on the track and street alike.
