Description
Mini racing demands a chain that can handle sustained high RPM loads without sacrificing efficiency—the Renthal 428 R1 Works Chain delivers exactly that. With a 4,946 lb. average tensile strength and shot-peened alloy steel construction, this chain resists impact wear while extended bushings minimize friction losses to the crankshaft. If you’re running a 100cc machine competitively, this is the chain engineered for consistent, reliable power delivery across multiple heat cycles.
