Product Overview
The JT Sprockets MX-Series Steel Self-Cleaning Front Sprocket (Part #JTF1901.14SC) is a competition-grade drivetrain component engineered by JT Sprockets, the world’s leading manufacturer of aftermarket motorcycle sprockets. Designed primarily for high-demand riding styles including Motocross, Off-Road, Adventure Touring, and Street, this 14-tooth front engine sprocket transfers mechanical raw engine power directly from the transmission countershaft to the rear wheel assembly via an industry-standard 520-pitch drive chain. Featuring integrated mud-relief technology, it acts as a robust direct OEM-fit substitute or gearing tweak to modify your machine's acceleration dynamics and power delivery curves. [1, 2, 3, 4]
Technical Specifications
- Manufacturer: JT Sprockets

- Size Profile: 14-Tooth (14T) tooth profile calibrated for a 520 final drive chain pitch.
- Bore Dimensions: 22.0mm internal / 25.0mm external diameter with a 15-spline mounting interface.
- Total Thickness: 8.8mm exact plate thickness.
- Weight Profile: Ultra-lightweight architecture at approximately 0.30 lbs (136 grams).
- Fitment Type: Direct OEM replacement upgrade slider matching original manufacturer spline boundaries. [1, 2, 3, 4, 5, 6, 7]
Key Features & Benefits
- Chromoly Steel Construction: Fabricated using premium aviation-grade chromoly steel matrices, heat-treated to absolute hardness to restrict tooth rounding, pocket wear, or gear breakdown under sudden acceleration spikes. [1, 2]
- Self-Cleaning Mud Grooves: Specially machined "SC" series mud relief channels at the base of each tooth face. These trenches systematically eject packed mud, grit, and sand that gather during extreme off-road use, preventing excessive chain tension spikes and maximizing overall chain lifecycle efficiency. [1, 2, 3]
- Hobbed Tooth Profiles: Every individual component is fully hobbed, computer machined, and drilled rather than cheap surface-stamped. This achieves incredibly narrow assembly tolerances and fluid chain-roller engagement. [1, 2]
- Strict Quality Validation: Passes through 10 individual hands-on factory quality control audits before distribution to guarantee zero countershaft micro-wobble and protect output shaft engine seals from tearing. [1, 2]
Confirmed Motorcycle & ATV Fitment
