i'm looking for a cool, solo, bratstyle seat for my kz650 bob. Is it easiest to make my own or are their solo seats out there that work better than others. right now i've got a cool tuck and roll JD seat but the seat pans got a pretty steep angle on it and it doesnt sit very nicely on the frame... any suggestions would be sick!

Make your own. It is fairly easy. I made mine using fiberglass resin and a pair of old jeans(who needs fiberglass mat). Use painters tape or tin foil on the surface you will be laying fiberglass on. The fiberglass won't stick to these materials. I used cardboard to fill the voids and create a flatter bottom.(this comes before the painters tape/ tinfoil.

Once the pan is done just pick up some foam and cover it. I hope this makes sense. Sadly I don't have in process photos.

End result a low pprofile seat that only cost a can resin.

IMO "brat bikes" look best with moto-inspired slab seats; not bobber-style solo seats. Check the seat on the Erwin 500 featured on this morning's ChopCult news. Simple, easy to make and relatively easy to cover with better-than-average upholstery skills. DB made this seat for Kim, and it looks great on the finished bike: all leathery and spongy and shit.

Kim tells me he buys old ski doo seats on Craigslist and uses the foam from these monsters to get the shape and density he likes. Duane shapes foam with an electric carving knife and a rotary sander.

It's pretty easy when you think about the basics.

If you tackle this project yourself, please shoot photos and tell us about it. I'd love to do a feature on DIY seat making down the road.

Although fiberglass is a good and well used option, why nut just cut some steal or aluminum sheeting up? i think its easier and a lot less messy, and has more class.

fiberglass is lighter. a can of resin is pretty cheap. and not everyone has access to the tools needed to go the metal route.
just my guess.

either way, i think metal is a little easier to work with.... in any event, just form a flat pan to fit the application, using an industrial strength spray adhesive, attach foam, trim to size and shape desired, and cover... simple as pie! remember, "Patience is a virtue"

What gauge of steel would you suggest, and what are the methods of attaching mounts? Thanks.

Here's a few I did. The first long black one was fiberglass, just tape over the whole area you want to shape, lay the fiberglass and sheets, let dry and trim to size. Then shape foam and rivet to fiberglass. The next two I did with steel, and I think they were easier actually 1/8th inch sheet, bent with vice, 2x4 whatever- cut, and shaped with hammer, crude, but effective. Shape the pan, shave the foam, glue and rivet, there you go.

thanks for all the awesome suggestions guys, nak, thanks for posting that picture of your bike, that slim seat looks sick!! i do like the idea of making one myself so that with probably be the route i go, and i'll for sure post pictures! any suggestions on a good way to mount up your seat? how did you guys go about doing it??

howie j dog: i've never made anything out of fiberglass before, but i like the idea of just taping off the area then doing it, but what do you mean by lay down the fiberglass and sheets? if you could send me a message with some tips for making the fiberglass seat pan i'd really appreciate it!! and anyone else who has tips or a step by step on making a fiberglass seat pan i'd really love to hear about it!

Re: what kind of metal to use; I've seen more than a couple street signs used for seat pans. Easy to find on the side of the road, especially if somone has hit one in their car right before you walk by to throw it in the trunk...

I've tried the street sign. It's a little flimsy. I think the standard street sign is 18 gauge. I would go with something a bit thicker. At least 16 gauge. But, I am sure you can make a street sign work if you had the right reinforcements.

I really like the style of the first seat howiejdog posted. If i do go the bratstyle route instead of a rigid for my xs, i am deffianately going that route.

Here's the seat from my personal bike and the bare pan for the ERWN SR. I made them both out of aluminum and the steel strap with bungs/t-nuts welded up. I like aluminum for weight savings & ease of working with. Anneal the aluminum and it will shape pretty easily. I use the steel so the threads are durable I'd hate to have to tear a seat apart for stripped threads. The steel bung strap held on by a counter sunk allen coming up from the bottom.
My personal seat I bought a banshee/Quad seat foam from Ebay and carved it with an electric kitchen knife and di the fine finish shaping with a bench sander and a bench grinder. You have to be a bit gentle, take you time & it's messy as fuck but you can shape it really well.
Duane Ballard sewed & covered both.

That said - I have a glass pan on my sporty right now and I really wish I had gone the metal route. Next time around and in the future, I will probably stick to metal seat pans.

I did an easy one on a sporty last year.

Trimmed the stock plastic pan to fit frame rails.

Then craved foam with an electric turkey knife and finished it with a flap disc on an angle grinder.

Did two homemade covers with help from Mom.

Finally broke down and had a pro cover it. Duane Ballard. It was way better then.

my friend used a street sign on his bike for a cafe seat
cut it to the dimensions he wanted
then used the blue camping foam mat( like you would put under your sleeping bag)stacked in layers
then used carpet batting/foam for the top cushion layer
glued it all to the street sign
shaped them both with a knife to give him a nice cafe hump.
came out pretty slick.

I win! I only used one layer of the blue foam mat :) All jokes aside the blue camping mats don't shape very well.

true true.
they also make a horrible mess when you're shaping them...i walked into my shed after my friend got done working on his seat and it looked like there was blue snow everywhere!

Hey Billdozer, whats the verdict on that mass produced seat you guys were talkin' about (the one modeled after your sporty one)? One of those might help this cat out.

i use the original seat pan and trim it up. Its cool on the jappers cause you can open the seat like it was originally mounted. The original foam is usually good to use too turkey knife trim and good to go. I even reuse the og cover just trim it down and remount it. I mean thats what the brat style seats were originally anyway. pull the cover skin down the foam, recover. good luck yo

P.S. Im doing a brat seat today I'll post up a how too ,or how i did it thread when Im done . cool

I was gonna make a new thread with questions about fiberglass seats, but this one answered all my questions. Thanks for all the links, pics, and advice guys! Can't wait to post mine after it's done.

i picked up a sheet of diamond plate for next to nothing and bent it on my workbench. i posted the pics on here somewhere. since then, i've covered with the a fore mentioned blue camping foam and shaped it with a razor blade. only one layer. it's now covered with black marine grade vinyl and riveted around the edges. cost me less than 20 bucks to make. it was a blast, too. now that i've gotten my practice seat done, i'll build a new one.
