Product details :

Features

Reference: JTF546.12 — JT Sprockets standard steel sprocket 546 for 420 chain. Designed for urban and cross environments, this compact sprocket is aimed at riders who want to maintain a reliable and precise transmission on small displacement bikes.

Manufactured from SMC420 steel and produced using CNC machining, this sprocket features a sharp and uniform tooth profile that facilitates engagement with the 420 chain. Its standard version with 12 teeth offers a classic compromise for gearing: a responsive performance at low RPMs and durability against daily stresses or light off-road demands.

Material: steel (SMC420)
Number of teeth: 12 teeth
Chain pitch: 420
Type / version: 546 - standard
Manufacturing: CNC machining for precise geometry

Ideal for small motorcycles 50–65 cc, this sprocket is particularly suitable for models such as KAWASAKI KX 65 (2026), YAMAHA TT-R 50 E (2024), and SUZUKI RM 65 (2005). Simple installation and direct replacement to restore a healthy transmission: check the condition of your chain and sprockets during installation to optimize lifespan and safety.
