How to Install Memory Foam In a 2005 Yamaha FZ6 Motorcycle Seat

Introduction

This is a how-to for installing memory foam found in consumer-grade pillows or mattress pads into a motorcycle seat. The seat used is a stock seat of a 2006 Yamaha FZ6. I found that the seat was slightly more comfortable with the memory foam installed. The real advantage was relieving nerve “hot spots” and pinch points that resulted in a numb left foot on any ride longer than an hour.

Tools Needed

  • Exacto/utility knife — if I had to do this over again, I would have bought an electric carving knife for ~$30 or so.
  • Marker (I used a Sharpie)
  • Ruler or tape measure
  • Staple gun
  • Flathead screwdriver
  • A lovely assistant. Or your ugly friend. Just make sure they have an extra set of hands to help you.

Instructions

  1. Remove the seat from your FZ6.
  2. Remove the staples from the underside of the seat, starting from the nose. I thought the rear of the seat might be too complicated to properly reattach. I removed the staples from the nose all the way past the black bumpers at the bottom of the seat (where the latch is).

  3. Pull the upholstery back, exposing the foam pad.

  4. Ready the memory foam insert. I used an inexpensive neck pillow purchased at Costco. I cut out a piece about one inch thick that fit between the contoured part of the saddle and left 1″ on either side.

  5. I marked the stock seat with the dimensions of my foam insert.

  6. Start cutting the stock seat with the utility knife. I made a cut one inch deep and then the width of my markings. Turn the blade and make another cut about an inch or so across, and then back up again, making a rectangle shape.

  7. After making several cuts, you will have an uneven bottom surface. I trimmed this up the best I could with the utility knife. [[image:IMG 3185.JPG|thumb|none|Step 7]]
  8. Place the memory foam insert into the stock seat. You may have to trim the insert or the stock seat to make the insert sit more flush. The memory insert is just slightly taller than my stock seat, to allow for compression once I sit down.

  9. Stretch the upholstery back over the foam. This is best accomplished with someone helping you to keep the upholstery tight while you go to work with the staple gun. I reattached the upholstery twice and it still wasn’t as good as the original. It did, however, look close enough on the second try.
