JT 420HDR 13/47 Reinforced Chain Kit - Standard Sprocket
Designed for urban use and 50 cc motorcycles, this JT chain kit includes a reinforced 420HDR chain, a sprocket, and standard steel rear sprocket. Ideal for riders looking for a robust and easy-to-install transmission, it is suitable for the listed models, but always check the compatibility of the components with your vehicle before ordering.
Main Features:
- Chain: 420 HDR with XS-Ring seals for improved sealing and lubrication of the links.
- Sprocket & Rear Sprocket: standard, steel material — designed to fit the 420HDR chain for precise coupling.
- Color: black/steel, weather-resistant finish.
- Usage: urban-oriented, compatible with several small models such as the YAMAHA TZR 50 (2010–2012).
In practice, the HDR chain and XS-Ring seals limit wear and reduce maintenance frequency compared to a standard chain without seals. Regular installation, adjustment, and checks are essential to ensure the longevity and safety of the transmission.
