My gl1500 seat mod for a aching butt

Postby virgilmobile » Wed Oct 03, 2012 3:30 pm



I've only got a short run due to the rain here but this weekend promises a 200 mile ride.
Previous to the change,45 minutes was max before a necessary dismount.
It's just me.You know...no padding.
I based my design on the Air Hawk design.I tried one but it pressed so hard in the tail bone,I had back problems for a week.
I removed varying amounts of each "cell" until it dissipated the load evenly.
I tested it setting on a chunk of plywood.

Looks like it should work pretty good. Just wonder how long it will las, will it crush out soon or stand up to some iron butt rides? Keep us updated.

I know it's huge money, but the Corbin seat on my 1500 is so amazingly beyond comfortable, like I've said before, I've done 15-19 hour days (consecutively) on it, and it's overall fatigue that makes me stop, not soreness. The only time I really have to stop is for fuel and biological relief. If I can swing it, I'm going to try to update it with a new heated one this winter. I'll sell my old one if that happens.

I bought a Corbin for my wife's PC800 for the same reason.

I like the stock seat on my 1500 for comfort, but my hips hurt after a few hours, I figure it's because the bike is so wide? Do you think a new seat would help that?

So far the only thing I can determine is what worked for me and it was trial and error.
Always try the easy and cheap things first.
My wife hates my seat, loves the stock one if it has a sheepskin cover.
I tried a cushion with the tailbone cutout with good results too.
I hated the air bladder cushion,she likes it.

I agree, Corbin is best seat for the longhaul. It will be next upgrade to bike, on my Vstar and I'm able to ride 700-800 miles before ride hurts. The Travelcade on Wing is good for few hundred miles but is designed for a heavier riderand wrong for my 175 pounds.

Nice looking mod on the seat . New foam will help I bet and this places it right where YOU want it.

My Diamond custom seat is awesome..I have 3 IBA awards and many 700+ mile days...In fact when I go out with my riding buddy we plan every trip around 700 mile days...A 500 mile day feels too short....In July I completed the IBA Great Lakes 100 ride (around all 5 Gret lakes in under 100 hours) in 68 hours and 20 minutes with 3 days of riding (750 - 750 - 1000 miles)

Love my Diamond - but it fits my butt and is broken in to my shape exactly..useless for anyone else I suspect...?

That was the idea.
For some of us who have tried the conventional methods and found no relief,a custom fitted pad may be necessary.
I got the idea from watching Discovery channels "how shoes are made"
Especially the part about custom inserts tailored to fit the individuals pressure points.
I just applied it to my "seat"
Walmart people got upset when I tried to sit on the Dr Scholls foot analyzer machine :lol:

Ha, yes I can imagine that. The computer would have a hard time matching a shoe number to your butt imprint.

It was worth a try....it did give my a starting point.
After I cut the cushion into 1" square cells,I started removing small amounts in the pinch area till it evened out the weight.
I actually set it on a piece of plywood to get the worse case scenario.
After putting the bottom pad on I couldn't feel any pressure points after 30 minutes setting on the plywood.
Now add that to the 4'' of foam in the bottom and it should end up great.
If your interested...here's a link to what I was so interested in and adapted to my seat.

Ok everybody.....here's the results......YUCK :cry:

For the first 30 minutes it was great and then became horrible....Why ?????

The sculptured pads did there job,however only while sitting still...The pads compressed into a perfect fit and felt like concrete mold of by butt...with only 2'' of OLD original foam under that, I lost most of the cushioning from the bikes vibrations.

It was comfortable to sit on but not ride on....Oh well.
On to the next plan.
I need form fitting AND cushioning.....Hmmmm...I got a idea....Aqua seat.....I'm looking into that.
I can buy the bladder for $15...replace the bottom 3" of foam with new auto seat foam,then the bladder,add another inch of foam and cover it up.
Sheesh...my head hurts almost as much as my butt.I gotta get this done soon.Perfect weekend for a really long ride to the Gulf Shores.

I am having my stock seat modified on the 16th of this month at a shop here in NC called Mean City Cycles, in Maiden, NC, I found them thru another site I visit. We emailed a couple times and then spoke on the phone, they offer different seat options and it is a lot cheaper than an aftermarket seat, I will post a review after I ride it some, and let everyone know if it was worth it, I believe it will be.

So far I got the bottom rear seat from a 2009 impala.Plenty of nice thick foam.I'm adding a lumbar air bladder 3/4" below the top with the compressor built into the seat from a 96 explorer.
The stuff came from the junk yard.the foam is great and the bladder is good.
Air ride suspension for my butt!!!
I hope.

I had a 94 Explorer with that lumbar air bladder/compressor setup. It was plenty powerful to move the lumbar in/out, but are you sure it will take the load of being sat on, over bumps, etc?

It's a re-use.Not intended for this application.
I'm sure I'll have to 'lift' a bit to get the bladder to fill.
The bladder seems sturdy enough.I filled one a little and bounced on it pretty hard trying to burst it.It held.
It's experimental and I'll post the pictures if it works.I don't want a repeat of the previous attempt for everybody to wag there finger at. :)
I've got the time to try this.I really want a DIY fix for the hard seat rather than just sitting on $700.It's just the point of knowing why and how.
Anything can be fixed if you throw enough money at it and I'll probably end up paying for the knowledge anyways.

From reading, what I discern is that it really is a black art of mixing various foam densities at different parts of the seat, in different layers and in different orders. That's the main reason I didn't tear into my wife's PC800 seat, and instead just ordered a Corbin for her - I know I love the Corbin on my bike, and I didn't want to spend weeks of having her complain that her seat was uncomfortable while I tried a different combination of foam materials, shape, etc. trying to get it right.

My wife said the original was fine and the car foam insert was even better.
I suppose 25 year old foam could get hard to set on.

She doesn't complain a LOT...but when it comes to her bike, if it's not just to her liking, she will complain, and being the resident bike-fix-it-make-it-right guy in our house, the complaints get leveled in my direction. :)

With the add on electronic switching for separated headset music,combined intercom,manual vox over-ride switching and now the air seat control.....my wife is asking about a wireless remote system to operate all of that instead of discrete buttons populating the passenger area.
Now she wants her own fader control....seems I can't get the volume 'just right' from the rear speakers.

Sheesh....I'm spending more time building this into a Mercedes than riding it.

I thought the solution for that was to buy her her own bike and teach her to ride. Now the list of "stuff" she wants me to add to HER bike is topping mine! :)

Wireless remote? Really? How about an Android app that controls it all via Bluetooth? :)

Hey, Wingadmin,
Did you go to Hollister for a custom fitting from Corbin, or order a seat off the shelf?
