At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 34T-420 in Red (206ZR-34) — a lightweight, race-bred upgrade built for riders who demand performance without sacrificing style. Designed to fit Honda Grom/MSX125 models, this sprocket swaps out your heavy OEM steel piece for a purpose-built aluminum component that shaves rotating mass, sharpens acceleration, and looks incredible doing it. Vortex's CAT5 process anodizes the sprocket in vivid red color first, then CNC machines it from 7075 aluminum, exposing bright silver highlights along the machined surfaces for a truly custom, track-ready appearance.

Beyond the eye-catching finish, this sprocket is engineered for real performance. Its unique tooth design is built to increase longevity and keep power delivery smooth and consistent, while the specially formulated 7075 aluminum alloy meets Vortex's own strict specifications for strength and durability. It's no wonder Vortex sprockets are trusted by champions on tracks around the world. Whether you're chasing lap times or simply want a sharper-looking, better-performing drivetrain, the Vortex CAT5 206ZR-34 delivers.
