The sprocket gear underwent heat treatment to enhance resilience against wear and tear. The sprocket is more wear resistant and more suitable for driving on rough mountain roads. This material will also help minimize wear and tear from climbing uphillMaterial: Metal
Important Note - Without changing the front sprocket, reducing the size (number of teeth) in the rear sprocket will increase top speed but reduce torque. Increasing the size (number of teeth) in the rear sprocket will increase torque allowing for greater hill climbing but will reduce the top speed

This sprocket doesnt have the same inner lip as the original which isnt the end of the world. It comes with new screws because the original tapered head screws arent ideal to use since the bolt holes are not tapered (countersunk) . I conveniently snapped a head off tightening the bolt that comes with the kit. Thankfully i was able to remove it and put the original ones in even though they dont fit right.
