Description
This special-order upgrade kit (x-ring chain & sprocket set) outperforms the standard Korean factory setup. It includes a gold 525 X-Ring chain, premium steel sprockets, and all the fasteners you need—even a fresh nut and genuine Hyosung washer. Made for riders who want reliability, strength, and less frequent adjustment, this kit is perfect for touring, daily rides, or spirited weekend blasts.
💎 Great power demands a strong chain!
We only use high-carbon chromoly-steel sprockets from trusted European/Japanese brands (SunStar, JT, Renthal, AFAM). This selection provides higher tensile strength and a longer wear life compared to generic Korea/China alternatives. By choosing an X-Ring chain over the basic OEM O-ring design, you get better lubrication retention and weather resistance.
| Hi-Carbon Steel Sprockets built for longevity. |
JapSpec X-Ring Superior sealing for less maintenance. |
| Safety Critical Hardware New lock washer & nut included. |
UK Weather Ready Stainless steel carrier bolts included. |

🔧 Install Tips
- Loosen First: Loosen the front sprocket nut while the old chain is still on and the bike is in gear with the rear brake applied.
- The Critical Washer: Ensure the genuine locking washer tab is bent back over the freshly torqued nut after tightening to prevent loosening.
- Torque Specs: Use a calibrated torque wrench for all fasteners to avoid damage to threads or shafts.
- Rivet Link: If you are unfamiliar with chain riveting, a local professional mechanic can secure the master link for minimal cost—safety is key.

Bought and Installed on RC 2018. Excellent strength, the full kit that is provided is excellent value for money and much better than other providers. Sprocket especially is a great upgrade. Visually it looks great, I will aim to get some photos added to show final product.
