Setup and Installation
This section outlines the general steps for installing the Ultima Chrome King Spoke Rear Wheel. Specific procedures may vary based on your motorcycle model. Always consult your motorcycle's service manual.
- Preparation: Secure the motorcycle on a lift or stand. Remove the existing rear wheel according to your motorcycle's service manual.

- Tire Mounting: Mount a tubeless tire onto the wheel. Ensure proper bead seating and inflation to the manufacturer's recommended pressure.
- Rotor and Pulley Installation: Install the appropriate 2000-Later style brake rotor and drive pulley onto the wheel hub. Use new hardware and apply thread-locking compound as specified by your motorcycle's manual. Torque all fasteners to the manufacturer's specifications.
- Wheel Spacers: Ensure correct wheel spacers are used. The wheel is designed for dual flange applications.
- Reinstallation: Carefully re-install the wheel onto the motorcycle. Align the brake rotor with the caliper and the drive pulley with the belt/chain.
- Axle Tightening: Insert and tighten the axle to the motorcycle manufacturer's specified torque.
- Final Checks: Rotate the wheel to ensure it spins freely without binding. Check brake operation and belt/chain tension.
