The JT Sprockets JTR478.48 sprocket is a simple and robust transmission part, designed to replace an original sprocket or modify the gearing. Made from C49 steel, it features a standard finish suitable for use on quads and roadsters, where ease of installation and compatibility with a 520 chain are expected.
Designed for easy integration on rolling stock equipped with a 520 transmission, this sprocket allows for adjustments in engine torque and acceleration behavior based on the choice of associated pinion. It is particularly suitable for installations on quads and roadsters, and fits models such as the CF MOTO 700 CL‑X SPORT (2025), the KAWASAKI Z 650 RS (2025), or the POLARIS TRAIL BOSS 325 (2003). For safe installation, adhere to the manufacturer's torque specifications and check the wear of the chain and pinions before installation.
