If you can stand the wait for carriage pop across to the UKGSers Forum and look up Denz0. The guy is an absolute genius and will rebuid your unit, including customising to you weight etc. He rebuilt a friends GSA unit, including the appropriate weight spring for him  for well less then 400. He is based in Croydon Uk though, so thats half a world away. Still looks a cheaper option thaan new though.
Yesterday I found a guy here in Aus who said he could rebuild the current shock as well. But he said he wouldn't because it wouldn't last.

it's better you go for some bigger bike that's capable of carying such loads.

The thing is, the GS1250 has a  carrying capacity of 216kg with a kerb weight of 249kg, the F900XR is supposed to be able to carry 219kg, which is also it's kerb weight. So it's 30kg lighter which is why I bought it.  At 72 those 30 extra kgs make a difference.

IMHO the problem lies in the fact that the F900XR's suspension build quality isn't to the same spec as the GS. I think the ESA does a superb job, even fully loaded, but obviously I should have increased the spring rate from new.

I test rode the 1250 RS against the 900XR (with BMW small screen) on the same day.
I found the RS widn roar slightly quieter of the  two - but both were noisier than a naked bike with a smooth flyscreen

Wasn't originally sure what was different on the white, but yes you're right it looks better. Darkening the silver side panels and changing the wheels to black are nice refinements.

I think I prefer the 2024 blue as well.

I'm using a Shoei GT Air. I don't think it's the quietest helmet out there.
But on another note. Went to my local BMW dealer to demo the r1250rs and the gs. What a torquey beasts in comparison. Wind protection and noise for me not as good as expected for motorcycles a tier above the 900XR.
A good thing that I tested these bikes, now I'm a little bit less frustrated about my windscreen.

Interesting - so you mean that the R1250RS and GS are a bit quieter than the F900XR but you still thought they were very noisy?

I'm starting to think that the only quiet bike with fairings is a full-on supersport!

Hi all. Just checking in after forgetting to visit the forum for a while, mainly because I've hardly been on my F900XR. With the nicer weather it's been the other bike getting more use.

I was thinking over the wind noise issue again a bit more, and decided that a lot of the problems I was experiencing in early summer were due to me stopping wearing a neck scarf due to the warm weather. But I rode the bike last weekend with a neck scarf and was still disappointed at how noisy it is.

Hyperpro springs are a life changer. When I swapped them on my Fz6 few years ago the bike changed. Better handling, better stopping overal all was better. Have in mind that I changed only front springs, as the rear stock is the same as Hyperpro.
I don't see why you need to change the front cartriges when only the rear shock feels spongy. For me personally - i'd order the Hyperpro rear spring and see if that makes a difference. If it is not satisfying go with change of the whole shock.
If you are going to change thins for 5k $ it's better you go for some bigger bike that's capable of carying such loads. Bare in mind that you got middleweight (900cc is the new middleweight but go figure) toruing/adventure bike (if anyone has notticed before F900 GSA the F900xr was in adventure section in the BMW site - now it is in the sport section) which is mostly for single person + some luggage.
Mine is going 75 000km strong and the only persisting problem is the one with hard neutral find when it's warmed up and in full stop. Other than that - fully enjoying the bike.

Maintenance and Servicing / Re: Fork oil change
« Last post by LCjohnny on Yesterday at 10:39:35 am »

I did this service on my F900R last weekend.  At 3 years, 11,700 miles, the fork oil was in surprisingly good condition. In hindsight I would have left it for another year/6,000 miles, especially considering that 2 liters of Type 4 fork oil from the dealer cost me over $87.  I only did a "dump and run", not a full disassembly of the forks.  With that method, I was able to get 475mL (~85% of dry capacity) of fluid from the right leg, which includes the damping cartridge, and 580mL (~92% of dry capacity) from the left leg.

Before opening the fork cap, I turned the fork upside down, shook up the fluid, and pumped the mechanism to try to suspend any grit that had settled into the bottom of the fork back into the fluid.  This seemed to work as the fluid was a uniform color throughout the draining process, there was no metallic sludge at the end of the pour like what is shown in Dave Moss' Dump & Run video and most others on Youtube.

 If you're draining the fluid without disassembling, make sure you have both the opening of the fork tube and the holes in the damper unit over your collection container, as oil will pour out of both at the same time when you invert it. If you spill some, you can use a small kitchen scale (~$10 on Amazon) to weigh a couple of dry paper towels, clean up the spilled oil with them, then weigh them again.  Then use the scale to add that same weight worth of fresh oil to the amount that made it into your measuring container.

I will send a sample of the used fork oil and a sample of the fresh Type 4 fluid to Blackstone Laboratories for analysis. Once we have the cSt@40C and the VI for fresh BMW oil, it will be easier to compare with 3rd party products and switch to something else.

Very helpful - thanks

I havent got ESA so am only quoting from various technical journalists.

I understood that ESA was just a cheap way for manufacturers to mask poor oem suspension rather than installing well engineered units?

So if i was you i would go for non ESA matris or YSS or Nitron front and back
