Complete chain kit with increased gear ratio.
Front sprocket: 21t
Rear aluminum sprocket: 55t
Chain: DID 530 VX (reinforced X-ring, gold)
The chain length is adjusted to the size of the sprockets. Always check the correct length before connecting the chain.
The 21/55 ratio is the most suitable for the serial gear ratio in Sportster 1200 since 2004. By changing the belt to a chain, the drive is much more stable.
