I love the look of the corsa seat. To my eyes the proportions of the slope and the body are perfect and the price is right compared to other slope back seat options out there.

The only thing I don't love is that gap.

I have one sitting on my PX right now. I've tried to go through older threads to see if there are any fixes. Only one I came across from Tierney, but he doesn't go through enough detail.

I don't need it to sit flush, but I'd like to close the gap a little. Without the seat pin it sits closer and is more acceptable. From what I can see the rear pin is the only thing holding up the seat.

Does anyone know if there is a shorter M8 seat seat pin? Currently using the one that comes with the sip rear adapter.

Another option that might help is if anyone knows of or knows someone who can fabricate another rear adapter plate?

The one that sip sent out is not great quality. I've already had someone cut of the things that stick out of the sides since I have the gas sensor and the little wing things were in the way. I also had to have the hole re-thread as it was to small.

Problem is that it's flat, so when it's mounted, it sits at a slant from the top of the gas tank to where the original seat pin would sit. That cause the seat pin to sit a little higher.

I was thinking of one that is stepped so that it sits flush to the body.

Any other ideas welcome.

SoCalGuy's bike were you can really see the gap.


Tierney's bike with a more acceptable gap.

I see what you mean. Do you have access to a big vise and large hammer? Time for some modest but forceful metal persuasion.

And yes, there are different length seat pins, look here: http://www.scootermercato.com/Home?search=seat+pin

Not too many tools or even a garage for that matter. I have no objections to having to bend things, but I don't even know where to begin.

I think most of the shorter seat pins are M7 size and not M8?

Yeah the gap bugs me too, but the seat's comfy so I haven't messed with it.

It's not the rear pin causing the gap, it's the location of the hinge pin on the front mounting bracket. If it's moved about 1/2" closer to the seat, the whole seat will sit lower. The latch in the back has to be modified too. Doable with some drilling n grinding.

I was thinking about that too. Guess I'll live with for a little bit since I don't have the proper resources.

Edit: Also I was thinking a shorter seat pin because I can't see any other place holding the rear up.

It's been many years since I had my P200E with this seat, but if my memory is right, a shorter seat pin won't help. The rear of the seat rests on two rubber feet that rest on the bracket, on the those two tabs sticking out at each side of the threaded seat pin hole.

The gap doesn't look all that bad from most angles, but lower would look nicer.
Perhaps one could use a short seat pin, and cut off the two tabs on the bracket, letting the rubber feet rest on the tank? Or maybe you can fit shorter rubber feet?

I do remember thinking that it's a pretty comfortable seat. Not squishy or springy, but by no means a plank with a little foam on it either. Ergonomically it put me in a posture that was just right for my taste.
