CNC Sprocket Adapter Kit For 80cc 2-Stroke Motorized Bicycle – 32T Sprocket, Black

Building a motorized bicycle?

This CNC adapter kit is exactly what you need to mount that sprocket solidly.

It’s designed for 49cc to 80cc 2-stroke engines—perfect for those classic Chinese motor kits.

The kit includes a CNC machined adapter (sometimes called a reducing gasket) and a 32-tooth sprocket.

Everything’s in black and built to keep your sprocket true and tight on the wheel hub.

It’s a custom bundle, unbranded, but made from solid metal to handle the torque.

Installation is straightforward if you’ve built one of these bikes before.

This part replaces or supplements the cheap rag-joint setup that usually comes with kits.

Get better power transfer and less wobble with this CNC adapter.

Made in China, but hey, that’s where all the good bike engine parts come from.

No MPN or UPC, just a solid upgrade for your build.
