Description
This special-order final drive upgrade package comfortably outperforms the standard original factory setup under intense road use. We build this comprehensive overhaul kit using premium high-carbon chromoly steel sprockets sourced from highly trusted European and Japanese manufacturers to deliver maximum tensile strength and an exceptional wear life. Each box arrives completely loaded with everything you need for a total transmission line refresh, packing a striking Gold 525 X-Ring link chain, a precision-cut front drive gear, a matching rear high-carbon sprocket, an authentic fold-down safety lock washer, a fresh center spindle nut, and a full set of unrustable stainless steel carrier bolts. It is the definitive option for riders who demand serious reliability, superior structural strength, and far less frequent adjustments during a restoration project.
Great middleweight power requires an equally robust final drive link. By upgrading your final drive system from a basic factory O-ring design to our specialized quad-lip X-ring layout, you secure significantly better internal grease retention and superior weather defense. Furthermore, this custom kit is engineered explicitly to lower engine rev stress during high-speed cruising. By optimizing your final tooth drive ratios, it allows the V-twin motor to run significantly more relaxed when touring, safely stretching your overall top speed thresholds while adding noticeable extra speed parameters within every single gear selection.

🔧 Install Tips
- Break the Front Nut Torque First: Always crack the initial tightness hold of your original front sprocket nut on the workbench while your old link chain is still mounted on the teeth. Keep the transmission clicked securely in gear and have a helper step down hard on the rear brake pedal to lock the output shaft from spinning.
- Fold Your Lock Washer Ear: Slide our fresh genuine locking plate onto the drive splines before spinning the new nut home. Once your calibrated hand torque wrench matches original factory tightness specifications, take a flat drift tool and a small hammer to fold the metal flap flat against the hex side face of the nut to physically lock it.
- Utilize a Calibrated Torque Wrench: Always use a proper hand-operated torque tool when tightening your output shaft gear and carrier nuts. Over-tightening can easily fracture the internal metal splines on your gearbox output shaft or warp your wheel threads.
- Secure the Master Link Properly: If you are completely unfamiliar with using professional chain breaking and rivet tools to mushroom the master link pins safely, do not risk a loose link on a 650cc twin. Take your new hardware down to a qualified local mechanic to ensure a secure, permanent connection.

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.
