I notice the front seat rubber grommet is only 1/8" thick . . . There is 1/4" play in the front. I added 3/8" rubber grommets to raise the front of the seat a bit and eliminate the play. I had the grommets from a rear rack.

The seat does slope forward. It looks like there is enough cover material to unstaple the front and add padding between the seat pan and the seat foam . . . to flatten the seat out.

Phase II to flatten out the seat (grout sponge seat pan mod), there is a cut out in the seat pan . . . Cut a grout sponge to fit the cutout:



For comparison with the stock sloped seat:



This mod makes a big difference to me. I do not like sliding forward due to the stock sloping seat. It does not change the seat lines and allows you to slide back bit for more leg room.

Remove the passenger strap for more comfort. There is extra seat material for this mod (use 1/4" staples . . . stapled in between the original staple holes:

Nice write up and a great idea....I probably need to do the same thing, the seat slopes just a bit too much forward for me too.

Yep, slide forward too much also. Thanks, nice post. I've recovered my own pool tables so this looks somewhat similar so I think I'll give it a try.

Ya, I wish it would have come like this stock.

Did you hand staple or Pneumatic stapler? I bet that seat base is hard to hand staple.

To level the slope on my MT-03, I skimmed off some foam. As an alternative, I do not know if the 09 seat has enough foam to do that, or if lowering a bit is needed. (I inserted a gel pad too to help comfort).

This sounds like exactly what I need, how thick was the grout sponge and did you need to taper it at the rear to blend in a bit?
I am hoping to do this this weekend, I bet it will be the last thing I need to di if it goes well. I just got the ECU reflash and it is nice and smooth.
Once the seat is fixed Highway 1 here I come!

One of the first changes I made but I didn't notice the slope at first I just did it to make the seat fit better so it was a win win. RR :cool:

I did this last night with an off cut of seat foam that i got for free at a local auto seat upholsterer. Because it goes under the OEM foam, once you put the cover back on and restaple it, it looks factory, just flatter.

I just did this seat mod. Sitting on the bike in the garage it is much better! I'll take it for a spin in the a.m.

My mangina thanks you!

Ride Safe.

I've tried grommets and some shims I made to raise the front of the seat, but I couldn't get any of it to stay put or work like I wanted. Then I came up with this fix and I am very pleased with it. It raises the front of the seat about 5/16" and it does make a difference. I bought a pack of 3/4" inside diameter rubber feet at Trust Worthy Hardware. I notched two of them so they fit over the molded post in the base. When I had the fit right, I used Liquid Nails to glue them on. I had to cut about a 5/8" deep notch that was about 3/4" wide at the widest point. My seat is a Seat Concepts and the foam is comfortable, but the angle kept shoving the twins into the tank. The seat removes and installs easier than before, there is almost no slop in the fit, and the rubber caps aren't going anywhere. The whole gig took about 20 minutes.

Nice mod. I just did this but all they had at the store were 7/8 rubber feet so that's what I used. They didn't fit as snug as your's, so I just drilled a small hole through the whole rubber foot/seat base assembly and pushed a nail through and bent the end. On tight, no need for adhesive, slick mod, thanks for the idea.

One thing that bothers me about the seat is the huge unsightly gap underneath... So mods adding shims and pads underneath are not the right way for me. Attached a picture looking at the gap I'm referring to... I noticed that the rearmost bumper wasn't even close to the seat, so I wanted to focus on the rear latch plate. With the plate removed, the seat was perfect (although not latched down of course) so the strategy is to lower the latch plate.

Put it in the vise to straighten out the bends a little bit, and enlarged the edge mounting holes for the flatter plate. Much better, and I could have gone further as it's still not contacting the rearmost pad.

Just pay to have it upholstered, better to fix the problem then try to mask it.

But the real question is...how does it feel? Does it feel like there is a grout sponge under your butt, or does the seat actually feel better? Does it result in the middle of the seat being either more firm or pushed up, which is already a ball killer, or does it really help in making the seat flatter and more comfortable? Inquiring minds what to know...

The additional foam is under the OEM foam, so it feels like the factory seat, but flatter. Like I said before.
It doesn't make the factory seat foam magically change density or anything, it just makes it flatter. Not sure what else I can say to describe it, really.
And hell, it's free, give it a try, if you don't like it, pull the extra foam back out, or spend a few hundred bucks on a seat that turns the bike into a lazy boy if you want to.

I'm probably one of the few people who think the stock foam in terms of density is fine...it's the darn slant that creates the problem. I just didn't want to try this and find that although the slant is gone, I now have a lumpy feeling under the middle of the seat. If this works, I'll give it a try.

One other question..in reference to the seat concepts "standard" seat...will the oem cover go back on using that foam set?
