The JT 420HDR 13/52 reinforced chain kit combines robustness and simplicity for urban machines. Designed around a 420 HDR chain with XS-Ring seals, it provides a sprocket-crown connection intended to withstand the demands of stop-and-go traffic and daily city rides.

• 420 HDR chain: reinforced construction, black/steel finish, suitable for repeated use and frequent starts.
• XS-Ring seals: improved sealing between rollers and bushings to limit lubricant loss and reduce dirt ingress.
• Standard sprocket & crown: steel crown, calibrated for direct mounting on many models equipped with 420.

This kit is particularly suitable for small displacement bikes and urban scooters/mopeds where reliability and ease of maintenance are important. It installs on many references, including the RIEJU SPIKE 50 (2005–2007) listed among the common compatibilities.

Important: check the list of components and the number of links required for your vehicle before ordering to ensure compatibility and correct installation. The JT 420HDR kit remains a complete and simple solution to refresh the transmission of your urban motorcycle.
