This JT DRIVE CHAIN kit includes a reinforced 420HDR chain, a 13-tooth sprocket, and a 53-tooth steel sprocket, suitable for urban use. Designed for the drive and transmission of small cylinders, it is aimed at riders looking for a robust replacement part that meets the standards of pitch 420.

Main Features:

• Chain: 420 HDR, black/steel color, with XS-Ring seals to limit lubricant loss and reduce wear on the links.
• Sprocket & Sprocket: 13-tooth sprocket / 53-tooth sprocket, steel sprocket, standard mounting for classic mechanical compatibility.
• Quality: JT standard range, designed for road and urban use.

The kit is well-suited for regular maintenance on small displacement bikes; it allows for the replacement of the chain, sprocket, and sprocket in a single operation to restore uniform drive. Be sure to check the alignment, tension, and lubrication of the chain after installation to optimize its longevity.
