At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Black, 36T-420 (206ZK-36) — a lightweight, race-proven upgrade engineered specifically for Honda applications. Vortex has built its reputation on the track, and this CAT5 sprocket brings that same championship-level engineering to your bike. Built from 7075 aluminum and finished with Vortex's signature anodizing process, this sprocket doesn't just perform — it looks the part too, with a striking black finish accented by bright silver highlights that only come from Vortex's unique color-first, machine-second manufacturing method.

Swapping to this CAT5 aluminum sprocket sheds unwanted rotating mass compared to a heavy OEM steel sprocket, helping your bike accelerate harder and handle more precisely. Whether you're lapping the track or just want your Grom or Monkey to look and perform like a purpose-built race machine, this sprocket delivers the durability and style riders expect from Vortex.
