    I fixed the overheating problem on my 1190 Ergo seat using a 20 watt DC-to-DC converter (Digikey part number 102-3216-ND). I could not get the seat's circuitry to work reliably for voltages much below 12 volts, so I set the voltage to 12.5 volts to provide a bit of margin. Regulating down the voltage applied to the seat's heating element from the bike's normal 13.8 volts to 12.5 volts, reduces the heating power by a factor of (13.8*13.8)/(12.5*12.5) = 1.22. That 22% power reduction makes the seat comfortably warm rather than burning hot. If you would like more info, send me a PM.

    Korndogg - did you directly attach the input line from the seat to the OEM harness line using a new connector that fits the OEM connector and get proper control from the bike? Your last post read as "you could" but didn't say "you did". That is my plan, but would appreciate any experience you can provide.
    Has anyone else?

    Just a quick update. If you want to wire the seat for bike control on the 1290 SA, you'll have to pull the cover off the rear portion of the seat and lift the padding. You'll find the controller for the heating element right at the back in the center of the pan. Cut the wires going to the element and splice on a new cable that has the correct harness connector on it (PN for the connector is posted earlier in this thread). Button it back up and enjoy. I removed the controller and all other cables just to clean things up, but you could leave it in place if you wanted to.

    Do you still have this bike / seat combination?

    I've just unwittingly bought an ergo seat complete with wiring kit, that was listed for the 1290, only to find there's nothing that matches the bike (2015 1290 SA) in terms of wiring. A photo of the underside of your seat (or anyone else who has had a 60307940000 seat converted), would be very appreciated.

    TIA!

    My advice, sell it (or return to sender if you can) and get the correct 1290 SA heated ergo seat. they make one that just plugs in now.

    I just purchased the 2 piece Ergo seat for my 2016 SAT - Installation was just "Plug and Play"

    I did the same thing last fall for my 2015, in case anyone was wondering if it would work on theirs too.

    The other issue I have with mine is a complete lack of heating controls for the seat on my dash. There's no listing in the settings either to enable them... only the heated grips. I think a trip to my dealer is in the near future :-/

    If I can't get control through the dash, there's a certain sense in keeping the one I've got and hard wiring it in

    I might do if I paid full price for it, but I got it brand new at a really good price (like the price for the non-heated version)... the proper seat will cost me another 60 notes! (I'm from Yorkshire, that's not gonna happen!) ;-)

    Hey everyone,

    Just purchased a used 2013 1190 Adventure, and it came with the one piece heated ergo seat, which I believe is only intended for the 1290.

    Do you know if there is any way of connecting it and controlling it through the menu just like the heated grips, maybe through some software update?

    If not, I will keep it anyway since it's really confortable and I prefer the look over the stock one. Doesn't get really cold here in Portugal, so connecting it would be an added bonus, but not essential.

    Ordered the one piece heated ergo seat yesterday for the 1290, largely based on the good feedback from this forum and others. Hoping to get the bike on the road mid April and will report back on first impressions then. Thanks to all those who contributed to this thread and others relating to replacement seats.

    I never reported back on the 2-piece I bought. Huge improvement in comfort - the "rolled forward" feeling of the OEM seat that made it hard on the lower back is completely gone. The surface appears more durable, looks better, and has a nicer texture for grip. KTM should switch over to it for OEM; for the price of these bikes the stock seat shouldn't suck.

    Anyone ever weigh these compared to the stock one piece SAR seat?

    Got it figured, found my plug under the plastic blank off piece up near the tank. Plug and play as well on my 1290s. I wish they had one that matches the original 1290s design of the cover. But I can tell instantly it is a more comfortable seat. :)
