The JT Sprockets JTF555.14 sprocket is a steel sprocket with a 428 pitch, standard version 555, designed for motocross use. Engineered for sprocket replacement or gearing adjustment, it combines precision machining and materials specified to meet the demands of off-road motorcycle transmission.

• Material: steel (high-strength SMC420 alloy)
• Number of teeth: 14
• Chain pitch: 428
• Machining: CNC for precise tooth geometry
• Version: 555 - standard, lightweight and optimized design

The CNC machined finish and SMC420 alloy provide the sprocket with a consistent tooth profile and mechanical strength suited for the stresses of motocross: aggressive starts, RPM changes, and lateral forces. Its lightweight design minimizes rotating mass while facilitating chain engagement for smooth and responsive transmission.
