I can't possibly be the first to think of this but, before you buy an expensive aftermarket seat, consider trying this easy modification to the stock seat pan of the ST1300. It will allow you to use the highest position in the front and lowest in the back. You might still have to flex the seat just a little bit to get it on the lower step in back but it will work and the seat position looks totally great on the bike. It's amazing how much difference this seemingly small adjustment made to my riding comfort. It feels like a new seat!

BTW, I am 6' with 32" inseam. I also have the MCL riser plate installed. I had been using the seat on the top position in front and middle step in back and, although that was better than anything else, I was still getting a lot of chafing on long rides - the whole "hot, fidgety, sliding into the tank" thing. Not that it's a miracle cure or anything, but with this new configuration, I was able to ride 420 miles in one day last weekend and could have easily done more. I couldn't believe it myself!

The first step is fairly self explanatory (I think).

Perform the next step (picture 2) on both sides of your seat, of course. The whole idea here is to create more "wiggle room" to push the seat forward so you can get it on the lower position in back. You are creating more clearance for the metal tangs (attached to your bike) that hold the sides of your seat flush to the bike's body. The tang will actually poke through the slot you have created by shaving the plastic as shown.

This is probably about the best tool to use for the work in picture one. You might be able to figure out another way. The only other tool I used was a heavy duty "exacto" knife. You can also remove the rubber bumpers that the back "steps" normally rest on to gain yet another 1/4 or so lower in back (although they do soak up some vibration and are there for a reason). The entire job took me about 15 minutes.

Try it. I think you'll like it. If not, nothing here prevents you from going back to the other stock positions if you don't get the results you were hoping for.

Cheers!

For the "inseam challenged" and those who like a "butt pocket" not the feeling of sitting on a padded pole.... this mod retains the appearance of an OEM seat, until you sit on it.
Remove the cover. It is stapled on. Gently remove the spong/rubber from the seat pan. Turn the rubber over. Make all changes from the underside only. Starting at the back sculpt out (I used an electric carving knife and an abrasive wheel in a drill motor) an arched channel about 1" to 1 and 1/2" deep, approximately the same arc as the top of the middle front of the foam. When inverted back onto the pan and the cover is restapled, the seat looks unchanged, but when you sit on it, the unaltered foam at the outer edges in under the cheeks of your sitter is firmer and the middle sinks under your weight to form a "butt pocket" which moves weight from near the midline of your sitter to the outer "cheeks" for a more even distribution of weight. This effectively lowers your sitting position about 1/2 to 3/4 inch. Then turn the seat over to access the bottom of the pan with either a Dremmel or other router tool. Carefully remove about 1/2 inch from the lowest position "step" and make sure to enlarge the holes into which the two metal "half loops" on the frame are fitted. When you are done, the overall reduction in seat height for those 5'9" and under (I'm 5'7" w/27" inseam... definitely a challenge) by over an inch. Whereas before the mods, I was able to put down only both tip toes at a stop. Now, I can "flat foot" both feet wearing boots with ordinary 1/2" or so thick soles...... If you are in my area and want it done, come by....call first... JR STOC 397 grumpy@eastex.net

Thanks Mike,

Yes, you showed it to me on our last ride. I did all that and still can't fit it in. I'm O.K. with it for now and don't want to mass with it too much. I'm still thinking of getting an aftermarket seat one day. Not sure yet which one. Sargent uses stock molds but if I go with Russell, they need the original one.

Thanks and hope we can get together again.

Thanks JR,

This is something new. I'll have to look into it.
