JT DRIVE CHAIN 420HDR 13/53 kit, designed for urban riders seeking a robust and easy-to-maintain transmission. This kit combines a 420 HDR type chain with XS-Ring seals, a standard sprocket, and a standard steel rear sprocket — together forming a reliable drivetrain for daily commutes and frequent starts in the city.

Main Features:

• Chain: pitch 420, black/steel finish, HDR type with XS-Ring seals to minimize lubricant loss and slow down wear.
• Sprocket & Rear Sprocket: standard steel, designed for easy installation and precise fit with the 420HDR chain.
• Usage: suitable for urban environments and small displacement bikes where durability and transmission consistency are essential.

Installing a complete kit makes it easier to adjust tension and ensures consistent drivetrain geometry between the sprocket, rear sprocket, and chain. Compatible with several 50cc models, it is particularly suitable for the DERBI SENDA 50 R (2000–2002). For optimal longevity, follow the recommended lubrication and adjustment intervals.

A pragmatic choice for riders looking for a reinforced chain, good wear resistance, and hassle-free installation.
