    new seat for SR400 fi.

    Hello,
    I found on ebay an OEM seat in very good condition and a reasonable price....and will be the base of my future custom seat.

    After seeing the costs of shipping and customs from japan or tahiland, the seats I like for the SR400 were prohibitive, and I have found few options with grips specific to the FI model
    So I have taken the route to do it at home.

    Simple option ... retapizar the oem to taste without modifying anything else .....

    or better... reduce the foam and retapizar ....

    or... clone the base... modificate... and clone the model....

    I'm already at it ....

    I'm going through a similar journey as well. I have the Daytona 2010+ FI seat mount kit which "promises" to allow us to FI riders to install older SR400 aftermarket seats. I plan to mate it with a motolanna cafe seat but after an initial glance, I'm not sure it's even possible. The seat mount kit lowers the battery and provides a lower profile knob/post for the front seat mounts but i think that may still hinder the motolanna. Will know more this week when I have time to try again.

    But yeah, options sure are limited for FI!

    Also to note is the older style seats seem to be shorter forward of the post.
    I cant be model / year specific, but its something you should measure. There may be a gap between the seat and your tank after install.

    Hello, the image I put, is a model I saw on yahoo https://page.auctions.yahoo.co.jp/jp/auction/l378199519 ,
    i'ĺl make the experiments molding the foam of the new seat that I bought, until lower enough to eliminate the side cut that comes from factory. :enojado:I wonder who designed these..... shapes ...


    The following, upholstery again with a classic pleated design, if I cant take advantage of the cover. or in other case, take new material, keeping the new original seat for government inspections. .

    Previously... make a mold in fiber with the base disassembled, to have it in the future .... you never know, jejejeje.


    You will agree with me that :Rodar los ojos:.. these lateral angles are intolerable

    Hi Jose,
    I'm considering same action too this summer, but need to find cheap stock seat first.
    I found these images that I'll follow with mine, might help with some ideas,
    it's keeping all original, but with little foam cut far better looking than stock.Click image for larger version.

    I have taken advantage for tests later and at the moment, I will not modify this base ... only the foam and upholstery, what if I have clear is that if I touch the base I will have to change rear fenders

    So the first objective replicate base and do a cheap upholstery test

    Promised I'd update you all on my Motolanna.

    In short, the fitment is pretty horrible and even with the Daytona Seat Adapter kit for 14+ FI models, it DOES NOT WORK. Let me correct myself, it doesn't fit without modification.

    The Motolanna seat is roughly 24" but does not meet up to the tank. There is a gap.

    The top tabs DO NOT allow you to clear the frame to slide through. The right side has a bolt obstructing clearance and it's also spaced TOO NARROW. Here's two pics showing what I mean.

    On a whim, I decided to still give it a go and drilled out the rivets holding the top tabs. The idea was to RE-RIVET them WIDER so I could make it fit. After some test fitting, I decided to abandon that idea cause those metal tabs just seem like a horrible idea altogether. I just removed them altogether.

    Next, I lined up the rear holes and used the supplied bolts to secure the seat. The ANGLE of the bolt holes are HORRIBLE. It's not a complete vertical position, as required to fit through the frame. I ended up BENDING the bolts in order to thread them through the frame. And well, here's what it looks...

    Not exactly happy so I'll be abandoning the Motolanna to continue my search for something better. Perhaps Tuffside? I just thought the Motolanna would be a good choice as I see a lot of reputable builders on Youtube use it.

    That does look like a seat designed for a completely different bike that is just sat on top of the frame rails

    ^ that's exactly what I thought when it arrived. But sure enough, it was identified as a SR400/SR500 seat. I also just learned this style seat is an abundant knock-off from the Nitroheads seat, which has better fitment, quality, and a less pronounced gap with the tank. Oh well, lesson learned...

    Hello, finally finished the classic seat 1.0 ... this first experiment I think it has been quite acceptable
    As you know, I used the base oem because as you say, the seats that are seen on the web do not clarify many if they are valid for the FI, so it has remained .. for now, although the back termination is not aligned with the plastic , Without it, I think it looks even better, with aluminum terminals could improve the look ..
    I wait your opinions, greetings
