Review on PGN Roller Chain Feet Connecting: Enhancing Efficiency and Durability by Andrew Frison

I originally had a 420 chain on my mini bike, this chain is thinner but goes straight to the sprocket. When you go to a torque converter setup, this cleans the pulley and backplate, and if you install it properly, it doesn't rub like a 420's chain. I had plenty left over if I wanted to build another one. It is already lubricated and the extra connecting links are much appreciated.
