So I've been contemplating getting a new seat for the bike....but instead I think I'm going to try and modify my stock one instead. I found a really good site with tons of info (Modify Seat). I'm pretty much going into this completely blind.....anyone have any good advice/suggestions they are willing to share?

I probably won't actually start this project for a week or so, but I'll be sure to document and share everything that goes wrong. In the mean time, consider this a thread in progress....
 
Just like this.

Hey Shaggy,

One of our guys with a red FZ6 just trashed his bike from a rear end. The seat is totalled. Maybe ou could get it cheap and do the mods on that until happy?

Nelly

Good luck

your braver than I am! I have read up on doing this by adding some gel type material under the seat cover and that looked doable but i dont trust my skills at arts and crafts too much.

I was thinking about picking one up from ebay (~$60 shipped) and working on it. But I'm trying to keep my costs at a minimal because I'm fairly certain that I'm going to hose this up in some horrific fashion. If I don't spend a lot of money and I fail so miserably as to make my seat unsalvagable, I'll just order a new seat from corbin or sargent or whoever and I won't have lost too much money. That being said, if someone wants to donate an old seat for cheap, I won't turn it down.
 
That's great you're doing this cause I was actually thinking of tackling that project also.
I've been to that DIY site & it doesn't look hard. The only thing is getting the staples back in the base. Let me know how that is & if you have to get an air or electric stapler w/some power to punch 'em in. I was actually wondering if you could just use spray on glue & the same staple holes?
So keep us posted on the mod.
(BTW - I just did your light mod. Works great)
Thx,
Bill
 
Before I tell you what I did I should warn everyone that this is my first attempt at any upholstry work. I knew going in that the results were not going to be pretty. I was ok with that as long as it was comfortable. If it lets me ride longer and farther, I could care less what it looks like. Nobody's going to notice as long as I'm sitting on it. That being said, here's how I did it:

Step 1) Gathered all of the materials:
  1. 2 Inch think rebonded foam (base material)
  2. 1 inch thick high density polyurethane foam (top layer, really soft stuff)
  3. 1/4 inch neoprene foam (covering/smoothing)
  4. Angle Grinder + sanding pad
  5. Staple gun with 3/4 inch staples
  6. Dust mask and saftey glasses (foam particles get EVERYWHERE)
  7. Spray adhesive (for gluing foam together)
  8. Some high grit sand paper (for roughing out cuts)
  9. A sharp box knife or razor
  10. Poster board (not really necessary)

Step 2) To figure out how I needed to shape the saddle to make it more comfortable I had a friend take some pictures of me sitting on the bike. It's pretty obvious from those that my main problem is my long legs and wide hips.

index.php


In order to figure out just how much wider/longer I need to make the saddle I sat on a piece of poster board and traced the outline of my butt, then I identified the points where the majority of my weight was resting (sitting bones)

Step 3) Remove the cover from the saddle. At first I thought I was going to be able to reuse the original cover so i didn't take it all of the way off. Later on as you see how much material I added it's pretty obvious I was being overly ambitious. In the end I bought some new material and recovered the seat with that.

IMG_0072.jpg


Step 4) Using the grinder and being very careful/gently I removed as much of the material from the back of the seat as I dared. I wanted to make the drivers seat longer so that my long legs wouldn't force me to sit so close to the tank. By the time I was done, the original foam was only about an 1/8 of an inch thick at the back. I also removed material from the seat pan to try and decrease the incline (again to stop from sliding into the tank). The last major subtraction was a large rectangular cut towards the front of the seat. My plan here was to widen the seat out and provide aditional support for my thighs.

What's not easily visible in these pictures is that I used a piece of high grit sandpaper and roughed out a couple channels in the foam under the points I identified earlier as bearing the most weight when sitting. I hoped that this would better distribute my weight across the whole of my butt.

Step 5) Now I started to add more foam to the seat. I started by filling in the channel I cut in the front with a 2 inch thick piece of rebonded foam (this stuff is dense and makes good support material). I added a couple small triangular pieces to the edges where it stuck out to help support the "wings".

Step 6) Next I added a nose by taking a few piecse of the soft poly foam and gluing them together into a pyramid. I attached this to the front of the saddle on top of the new rebond and then smoothed it all out with the grinder.

IMG_0083.jpg

IMG_0084.jpg


At this point I decided I wanted a little bit more support around the edjges so I cut some 1x1x8 inch pieces of rebond and glued them around the outline of the seat. With this done I roughly cut a piece of the soft poly foam and place it on top of the seat. This was more of an afterthought, the more soft foam, the more comfortable it's goign to be.....right?

IMG_0085.jpg


The last piece of foam was a shet of neoprene roughly cut and shaped to cover the entire drivers seat. This was mainly to hold everything in place and smooth out the imperfections.

Step 7) As I mentioned earlier, I had initially planned to reuse the original seat cover. But it's pretty obvious that I added WAY too much foam for that to be an option. I puchased a yard and a half of boat seat material from a local upholstry store and recovered the seat with it. I didn't take any pictures of this step (sorry), it's basically just stretch the material and staple it in place. I would recomend starting at the back and moving forward in a zig-zag fashion. Saving the front (where it contacts the tank) for last. Once everything was secured I cut off the excess and tightened up a few places.

Here it is mounted. It's not pretty but it's damn comfortable. I'll probably end up making some adjustments to it over the next few seasons. Maybe build up the front a bit more, try and take down the back a bit....not really sure, I'm just going to have to ride it for a while and figure out what I do and don't like.

All in all, I put about $115 into materials and I bought way too much. I have enough left over to do at least 2 more seats, maybe 3 if I can reuse the cover on one. Point being, if you are a little more realistic in how much foam you buy, this is completely doable for ~$50.

Nice write up.

What is boat seat material?
Sounds ideal.

Marine grade vinyl fabric. Same stuff that the original seat cover was made out of. I will say this, the new stuff is a lot sticker. I don't slide on it nearly as much as I did on the stock cover.

I've been under the weather for the past few days and it really kicked it up a notch today. So I haven't had a chance to really test this thing out on a long ride. I'll be sure to follow up with any changes I make when I finally get to take it for more than just a spin around the block.
 
shaggystyle is the Green Lantern!

If you could do that on an FZ1 seat, you'd be a real hero. Do you have ANY idea how uncomfortable the FZ1 seat is? It's like sitting on a cheap piece of WOOD. If you offer ANY FZ1 owner to fix their seat, they'll say YES in an instant.
 
Nice write up! Congrats on taking this on yourself! I'll admit it isn't the prettiest job but it is comfort you were seeking and sounds like you've gone a long way down that road. Hope you feel better soon and can give us a full rundown after a good ironbutt trip!

Thanks for sharing! Great job!!
 
Thats cool Shaggy. Since you have the extra you can do it several times untill you get perfectly comfortable and make it look nice. I usually screw up the first time I do anything new.
 
yeah, that's what I was thinking. I went ahead yesterday and pulled the cover off and tightened it back up again. I managed to smooth out all of the wrinkles and and made it look a bit better. Still a work in progress though.

Feeling better today so I'm going to ride to work. I'll take the long way in and see how it feels.
 
Hey - I'd like know what kind of stapler you used for this?
I have (had) a cheap electric stapler that I tried on the bottom of the seat (plastic) pan & it wouldn't go thru it. It just bent up the staples!
Thx,
Bill
 
Electric Stapler/Nailer Gun

.....and I used 3/8" staples. Sometimes, especially up around the nose, they wouldn't quite go all the way in. In those cases I'd just push them the rest of the way in with the tip of a pair of needle nose pliers. For the most part though it had enough juice to push them in flush. That one site I mentioned at the top of this thread recommends the Arrow Stapler, but I already had mine and didn't see the point in buying another.

Nice job on the seat, and who cares if it's not as pretty as it could be? Nobody will ever see it under your butt while you are riding! lol Anyway, I was thinking of doing this to my seat as well, and I was wondering what your source for foam is? I'm having a hard time tracking down any good quality stuff. Thanks in advance.
