WR125R 2026 Fender Eliminator Kit Installation Guide

Quick answer

This guide walks you through installing the Yoshimura V2 Fender Eliminator Kit on your Yamaha WR125R, covering removal, wiring, and signal setup.

Installation steps

1. Remove the stock fender: Unbolt the OEM rear fender from the subframe. Disconnect the taillight and turn signal connectors. Keep the hardware if you plan to reuse it. Common mistake: Forgetting to disconnect the battery before unplugging connectors can cause a short. Disconnect the negative terminal first.
2. Mount the V2 base plate: Position the new aluminum base plate onto the subframe and tighten the supplied bolts. The plate is model-specific, so it should align without forcing. Checkpoint: Ensure the plate sits flat and does not contact the tire or swingarm. Spin the wheel by hand to verify clearance.
3. Install the LED taillight assembly: Plug the custom LED taillight into the provided harness. The connectors are keyed, so they only fit one way. Secure the light to the base plate with the included screws. Common mistake: Reversing the polarity on the harness will prevent the light from working. Match the connector shapes exactly.
4. Attach the turn signals: Use the included OEM signal brackets for stock signals, or install the Micro Signal Kit using the 3D-printed mounting plates. Route the wires along the subframe and plug them into the harness. Checkpoint: Test the signals before tightening everything down. If they flash too fast, you may need a load equalizer (not included).
5. Reconnect the battery and test all lights: Reattach the battery negative terminal. Turn the ignition on and test the brake light, taillight, and turn signals. Verify that the brake light illuminates when you press the pedal. Final check: If any light is dim or non-functional, inspect the connectors for a poor fit or bent pins.
