Product details :

Features

The JT Sprockets JTF1903.14 sprocket is a drive component designed for riders seeking precision and reliability in transmission. Made of steel, this 1903 sprocket with a 520 pitch features 14 teeth, suitable for replacement operations or gearing changes on lightweight roadsters.

Manufacturer reference: JTF1903.14
Material: steel (SMC420 alloy)
Number of teeth: 14
Chain pitch: 520
Type: 1903 sprocket - standard version
Machining: CNC for precise tooth profile

The JT sprocket relies on CNC machining and high-strength steel to ensure a consistent tooth geometry — essential factors for smooth chain progression and controlled wear. Its design aims to remain lightweight while maintaining the robustness required for everyday or moderate sporting use.

Practical compatibilities: particularly suitable for roadsters and 125 cc models such as the KTM 125 DUKE ABS (2025), HUSQVARNA VITPILEN 125 (2024), and KTM RC 125 ABS (2024). Before installation, check the pitch and number of teeth of your original setup to ensure a perfect fit.
