Are the 2020 and 2021 F850GS seats the same?
« on: May 02, 2021, 12:53:32 AM »
Bought a 2021 F850GS.  The seat doesn't agree with my rear-end.  Sore after not too long.  I want to buy an aftermarket seat, Corbin.  Corbin says they do not have a 2021 F850GS to create a seat. 

So I'm wondering if anyone knows if the 2020 seat is the same as the 2021?  Has there been any changes?  While the seats that I can find do NOT indicate there is a change was wondering if anyone knows for sure.

TIA!

BMW doesnít usually change the seat mounting during the life of a bike, unless thereís a manufacturing fault. It looks identical and none of their press blurb mentioned changes so I think itís safe to assume a seat from any year will fit any other year. It certainly hasnít changed since the bikesí introduction.

Thanks for the response!  So even between generations?  Like the air cooled head seats will fit the oil cooled heads bikes?     Interesting and good to know!

No, only in the same model type - so all 650/700/800GS and 800GSA  parallel twins have the same seat mechanism, which is completely different to the 750/850, because the chassis, tank location etc. are not the same. But all model years of 750/850 use the same seat system. Ditto all years of R1200GS/GSA LC (and even the 1250 as itís more of an engine upgrade than a genuinely new model).

I suggest that you just check one of the online parts fiches and see if the part number is the same.

With the model year 2021 BMW introduced a new extra low seat option (which can be retro-fitted to any F750/F850) and also a new seat colour scheme (black/yellow) to match the bumble bee 40th anniversary edition.
Technically there have been no changes to the seat mounting since the beginning of the F750/850 range, so any standard or aftermarket seat designed for the F750/850 should fit all current and past model years of this range (K80 and K81).

The most significant change for the model year 2021 was the adaptation of the engine to EUR5 with the result that some of the mounting holes are now in a slightly different position and that engine crash bars and bash plates designed for EUR4 model may not fit the EUR5 version .

The F800GSA actually did have a unique seat due to the enlarged fuel tank which was located under the seat on those models. To get the extra tank volume they added a lot of lumps to the tank that had to be accommodated in the seat pan.

Otherwise, all correct.

Ah yes, apologies, I remember that I couldnít fit my Sargent seat on my 700GS to the 800GSA I owned afterward. At least in moving the tank they kept the seat the same on the 750/850.
