ENGINE SPROCKET, 13T
This sprocket was originally made for the Yerf Dog Spiderbox GX150. It will fit most GY6 engines without invert.
If you are choosing to eliminate a reverse box rather than replacing it, you can use this sprocket to do away with the complete setup cleanly.

We provide a disc brake sprocket that bolts to the brake rotor hub in a 44 tooth sprocket. Internal diameter can be 1.29″ and hole spacing is 1″ with an external diameter of 7″
