JT/JT 420HDR 15/48 Reinforced Chain Kit - Standard Steel Sprocket
This JT DRIVE CHAIN kit is designed for urban 50cc mounts and small-displacement bikes requiring a robust transmission. It combines a 420 pitch chain with HDR profile in black/steel finish and a standard steel sprocket: a set designed to replace the original transmission on compatible models.
- Chain Type: HDR, Racing quality
- Pitch: 420
- Seals: XS-Ring for better sealing of the links
- Sprocket: Standard steel
- Finish: Black/Steel
- Manufacturer Reference: Not provided
This reinforced kit is particularly suitable for urban use and riders seeking a transmission with "racing" characteristics on lightweight machines. Easily identifiable due to the black/steel contrast, it replaces the original chain and sprocket to restore compliant transmission geometry.
Main compatibilities (examples): RIEJU SMX 50 (2001–2002), RIEJU MRX 50 (2002). Always check the pitch and number of teeth (15/48) before installation.
