Hayabusa Mototeck Undertail Installation Instructions

Most Suzuki Hayabusa riders will agree that the factory-equipped rear fenders do little to enhance their machine's appearance. Installing an undertail kit from Mototeck Innovation will remove the flap-like fender and replace it with a streamlined piece for better styling and aerodynamics. To top it off, Mototeck's undertail incorporates a slick LED tail light and rear indicators, allowing you to toss those clunky stock signals. While some modifications to your Hayabusa's rear fender and storage compartment are needed, the entire job can be completed with little knowledge of your Hayabusa's electrical system and fairings.

Remove both seats from your Hayabusa. Unlock the seat latch under the left side of the rear cowl with the ignition key to remove the rear seat. Unscrew the bolts under the front of the rider's seat with a 5mm Allen wrench, then lift the seat off of your Hayabusa. Unscrew the passenger grab bar's bolts, hidden below the rear seat, using a 10mm socket and a socket wrench. Pull the grab bar away from the rear cowl.

Unscrew the bolts from the front of the rear cowl, using a 4mm Allen wrench. Remove the plastic rivets from the bottom of the rear cowl. To remove the rivets, depress the centre of the rivets with the tip of a screwdriver, then pull the rivets out of the cowl.

Lift the rear cowl slightly off of your Hayabusa's frame. Reach under the cowl and unplug the rear indicators and the tail light from your Hayabusa's wiring harness. Pull the rear cowl off of the frame completely.

Cut the rear fender off of the storage tray, positioned between the frame's rails, using a razor blade.

Lay the rear cowl onto your Hayabusa's frame. Slide the Mototeck undertail into place below the rear cowl and the frame. Plug the undertail's turn signal and tail light wiring connectors into your Hayabusa's wiring harness.

Align the mounting holes on the sides of the undertail with the mounting holes on the bottom of the rear cowl and the frame. Insert the plastic rivets into the mounting holes to secure the undertail and rear cowl to the frame.

Reinstall both of your Hayabusa's seats. Use a 4mm Allen wrench to tighten the rider's seat's bolts. Lay the rear seat onto the rear cowl and press down until the seat lock clicks into a locked position.
