Why Choose Superlite RS7?

The RS7 Series represents the pinnacle of steel sprocket engineering.

The exclusive tooth profile extends chain life and provides smoother power delivery, while the induction hardening process ensures the sprocket will outlast standard steel alternatives.

428 Conversion Benefits:

Upgrading to 428 pitch provides a stronger chain and sprocket combination compared to stock 420. The larger pitch handles more power and torque, making it ideal for modified engines or aggressive riding styles. When paired with a 428 chain, this sprocket delivers improved durability and performance.

Note: Requires 428 pitch chain (sold separately). Not compatible with stock 420 chain.
