Description

The Supersprox chain and sprocket kit provides a complete drivetrain refresh for the 2020-2023 Beta 390 RR. This package includes a 520-pitch MX chain, a cross-drilled chromoly-steel front sprocket, and a high-durability Supersprox Stealth rear sprocket. The rear sprocket utilizes a hybrid dual-metal construction, featuring a lightweight aluminum core riveted to a hardened steel outer teeth ring to balance strength and weight. The front sprocket is engineered from chromoly-steel for added longevity. Each kit includes a clip-type master link. Because of variations in gearing options and tire clearance, the provided chain length may be estimated. The chain may require shortening by the user during installation to achieve the correct tension. Users should always verify the chain length before securing the master link. For optimal performance, the kit is compatible with various premium 520 MX chain options from manufacturers such as DID, RK, and Renthal.
