Renthal Front Sprocket 13T 520 Chain Steel 501-520-13GP

A lightweight front sprocket is one of the most effective ways to reduce unsprung weight and improve throttle response on your motorcycle. The Renthal 13T 520 sprocket delivers measurable performance gains through precision engineering and materials science, not marketing hype. If you're serious about acceleration and durability in demanding conditions, this is the sprocket built to outlast the competition.

Renthal engineered this sprocket from 655M13 nickel-chromium steel—the same material specification used in professional racing—then case-hardened and core-refined it for maximum hardness without brittleness. The CNC-machined design includes self-cleaning mud grooves at each tooth, which actively shed mud and debris during operation rather than allowing buildup that would accelerate wear. The result is a sprocket that maintains sharp engagement with your chain lap after lap, whether you're on the track or in the dirt.

The 10-15% weight reduction matters more than it sounds. Every gram you remove from rotating components directly improves acceleration and reduces rotational inertia. Pair this with a compatible Renthal chain, and you'll notice the difference in how quickly your bike responds off the line and through gear transitions.
