Features

Manufacturer Ref: JTF555.14

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.

Typical compatibilities:

KAWASAKI KX 85 II (2026 - 85 cc)
SUZUKI RM 65 (2005 - 65 cc)
KAWASAKI KX 85 I (2026 - 85 cc)
