Attention: chain kits may vary depending on the vehicles: check the list of components and compatibility before ordering to ensure proper installation.
The JT 420HDR 12/53 reinforced chain kit (manufacturer reference 486979) is designed for urban riders seeking a robust and easy-to-maintain transmission. Built around a 420 HDR reinforced chain and standard steel sprocket & crown, this kit offers a reliable solution for restoring or maintaining the transmission.
- Chain: pitch 420, black/steel finish, reinforced HDR type.
- Seals: XS-Ring to limit lubricant loss between links and preserve internal lubrication.
- Sprocket & crown: steel materials, standard mounting (standard crown included).
- Usage: suitable for urban environments and daily commutes where reliability and endurance are sought.
Easy to install, this kit allows for a clear transmission behavior: more consistent torque response and smooth riding without the jolts associated with a worn chain. However, check the number of teeth and assembly type of your motorcycle before installation. Common compatibilities: DERBI SENDA 50 R / SM DRD RACING (years indicated in the product sheet).
