🔧 Installation Tips & Help

It is critical you follow these tips to ensure a safe installation:

**The Washer is Mandatory:** You must replace your front sprocket washer/safety lock tab at the same time. Neglecting this step can cause engine damage.
**Lock the Wheel:** Put the bike in gear and have a helper hold the rear brake to prevent the sprocket from spinning during torquing.
**Torque Right:** Torque the new nut to factory specification (consult your service manual) and ensure the locking washer tab is properly bent into place.
