Step-by-step guide to installing a fender eliminator kit on a Kawasaki Ninja 650 or Z650, including wiring tips and common mistakes.
Quick Answer
Installing a fender eliminator kit on a Ninja 650 or Z650 takes about an hour and requires basic hand tools. The key steps are removing the stock fender, transferring the license plate and turn signals, and connecting the wiring—preferably with plug-and-play connectors to avoid splicing. Always test the lights before tightening everything down.
What You Need Before You Start
Gather a socket set, hex keys, a Phillips screwdriver, wire strippers, crimpers, and electrical tape or heat-shrink connectors. If your kit uses solder sleeves, a heat gun is helpful. Also have the owner's manual handy to locate the rear wiring harness connectors.
Work in a well-lit area and consider using a rear stand to stabilize the bike. Disconnect the battery negative terminal before unplugging any electrical connectors to avoid shorting the system.
Removing the Stock Fender
Start by removing the rear wheel or at least the rear fender section—most Ninja 650 and Z650 models allow fender removal without taking off the wheel. Look for the bolts securing the plastic fender to the subframe and the license plate bracket.
Carefully unplug the turn signal connectors and the license plate light. Keep the stock hardware organized; you may reuse some of it, though many kits include their own fasteners.
Wiring the New Kit
If your fender eliminator kit includes plug-and-play wiring, simply connect the matching connectors. If not, you'll need to splice wires—use heat-shrink solder connectors for a weatherproof joint. Match wire colors (usually black to black, red to red) and avoid crossing grounds.
Before reassembling, test all lights: turn signals, brake light, and license plate light. This is the best time to catch a wiring mistake.
Mounting the Plate and Lights
Position the license plate bracket so the plate is visible and not angled too far up or down. Most kits are designed for standard US plates (4" x 7"), but check your kit's specs for hole spacing. Use the included rubber grommets to prevent vibration and rattling.
Mount the turn signals securely, ensuring they don't interfere with the rear wheel or suspension travel. Tighten all fasteners to spec but avoid over-torquing plastic parts.
Installation Steps
- Disconnect the battery: Remove the negative terminal to prevent electrical shorts while working near the wiring harness. Checkpoint: Ensure the terminal is secured away from the battery post.
- Remove the stock fender: Unbolt the plastic fender and license plate bracket from the subframe. Unplug the turn signals and plate light. Common mistake: Forgetting to unplug connectors before pulling the fender—can damage wires.
- Install the new bracket: Attach the fender eliminator bracket to the subframe using the provided hardware. Tighten to spec. Checkpoint: Ensure the bracket is level and doesn't rub the tire.
- Mount the license plate and lights: Position the plate on the bracket, using the grommets. Mount the turn signals and plate light. Common mistake: Over-tightening plastic parts—can crack them.
- Connect the wiring: Plug in the connectors or splice wires using heat-shrink solder connectors. Match wire colors and ensure solid connections. Checkpoint: Test all lights before final assembly.
- Test and finalize: Reconnect the battery and test turn signals, brake light, and plate light. Adjust aim if needed and tighten all fasteners. Final check: Go for a short ride to ensure no rattles or interference.
