Product Overview
The TAG Metals Race Front Countershaft Sprocket (Part #TCS-540-13) is a premium, competition-grade drivetrain component engineered by TAG Metals for high-horsepower off-road racing motorcycles. This 13-tooth front sprocket anchors your vehicle's primary drive assembly, transferring high-torque engine power cleanly from the transmission countershaft to the rear wheel configuration via a standard 520-pitch drive chain. Designed as an exact OEM replacement or gearing adjustment swap, reducing your countershaft to a 13T layout optimizes low-end power delivery, providing explosive acceleration off the starting gate and crisp throttle response out of corners.

Technical Specifications
- Manufacturer: TAG Metals
- Part Number: TCS-540-13
- Product Type: Drive Train / Front Countershaft Engine Sprocket
- Material: Case-hardened, high-nickel chromoly steel matrix for exceptional structural durability.
- Finish: Matte raw treated steel finish featuring oil-resistant protective anti-corrosion coatings.
- Size Profile: 13-Tooth (13T) tooth configuration mapped for a 520 final drive chain pitch.
- Weight Management: Lightened layout featuring CNC-machined structural radial holes to drop rotating mass without sacrificing tooth rigidity.
- Fitment Type: Direct OEM precision-fit bolt-on upgrade slider matching original factory spline patterns. [1, 2]
Key Features & Benefits
- Case-Hardened Core: Thermal induction processing hardens tooth surface layers to limit frictional power loss, rounding, or premature tooth breakdown under extreme loads. [1]
-
Self-Cleaning Mud Grooves: CNC-machined relief trenches between every tooth face actively eject heavy mud, grit, and track debris, preventing chain binding and extending chain life.

- Micro-Tolerance Broaching: Machined to exact factory dimensional limits to eliminate countershaft micro-play, keeping power delivery smooth and defending your output shaft seals from leaks.
- Unsprung Mass Reduction: Shaves away excess structural metal weight to maximize acceleration response and engine rotational quickness.
