Primary Chain Kit 420 for Sur Ron Light Bee – this kit replaces the belt and pulleys with a chain drive and two sprockets, offering significant improvements in two key areas: It is far more robust than a belt, especially in sandy or muddy conditions. It is more efficient than a belt, with a smaller contact surface and reduced friction. The Sur Ron Light Bee primary chain kit includes a hardened steel 13T motor sprocket and a 30T jackshaft sprocket, along with a pre-cut chain. The 13T/30T setup maintains the original gear ratio. Additionally, replacing the chain is much easier than replacing the belt, as it doesn’t require removing the swingarm. Show More Show Less
