Product Overview
The Renthal Ultralight Steel Front Countershaft Grooved Sprocket (Part #453--520-13GP) is a premium, competition-grade drivetrain component engineered by Renthal, a global racing force with hundreds of World Championships and US titles. This 13-tooth front sprocket anchors your machine's primary drive system, transferring raw engine power cleanly from the transmission countershaft to the rear wheel assembly via an industry-standard 520-pitch chain. Engineered as an exact OEM replacement or gearing adjustment swap, it features Renthal's signature self-cleaning grooves designed to prevent mud pack-up, making it ideal for motocross, supercross, and off-road enduro racing environments.

Key Features & Benefits
- 655M13 Alloy Matrix: Fabricated from high-tensile structural steel that is case-hardened to limit tooth rounding or accelerated breakdowns under immense gate-start stresses. [1, 2]
- Self-Cleaning Mud Grooves: Features precision-cut radial escape trenches at the base of every tooth face. These channels systematically fling away packed mud and grit that would otherwise get trapped between the chain and gear, eliminating high tension spikes and preserving chain life. [1]
- Precision CNC Machine Matching: Broached to hyper-exact factory clearances to reduce frictional drag against the chain rollers and eliminate countershaft micro-play. [1, 2]
- Drivetrain Longevity: Keeps engine power distribution completely linear, defending transmission output shaft seals from stress-induced leaks. [1]
