Hi all,

My steering damper has become 'ornamental' no damping action anymore. Looks likely some crud found it's way on to the LHS shaft and seal, allowing oil to blow out over time 😢 Is this a common issue, or am I simply one of an unlucky few?

Just considering my options, and trying to keep the £££'s low... any advice from those who've had a similar issue would be very welcome...

Option 1: Rebuild it myself. Sadly I can't find a rebuild guide, parts diagram, nor oil spec, and 'if needed' where the seals could be sourced. I'd imagine the internals are pretty basic. The shaft doesn't have any visible scoring... so best case 🤞 might be just a case of cleaning and rebuilding providing the original seals are undamaged and still serviceable (maybe)?? 🤔

Option 2: Send it off for a rebuild and service, who does this for the oem bmw unit, any idea of cost??

Option 3: Buy a used replacement in 'working order' 🤞... either bmw or touratech, hyperpro etc... These seem a little thin on the ground just now.. ?

Option 4: Buy a new replacement, the bmw non adjustable std unit is crazy expensive for what it is.... especially (vs) a quality 3rd party 'adjustable' unit. So if I had to, I'd likely look at the 3rd party route (these also seem more serviceable)... Anyone seen any good offers out there, or have experience of a 3rd party steering dampers... (good or bad)?

Oddly enough the bike rides just fine (at least on road) without the damper functioning, even at motorway speeds & luggaged up. Reminds me of my old hexhead :sneaky:

TIA

'Denzo' on this site does suspension re builds, don't suppose he does these dampers as well ?
 
Have you not heard of Motorworks??

They do second hand parts (genuine) and obviously new

Yes I owned a hexhead with 6 previous owners, so pretty much have frequent flyer miles with Motorworks 😂. Just a little reluctant to spend £140 on a used unit with unknown history. I know it’ll be covered for x months by mw. Although feel a service (if someone does that) should be less with a then known good and tested unit. Inc fresh seals, fluids, warranty etc

I tried for some gear linkage parts a while back from Motorworks for my R1250GS and checked again recently, and nothing in stock. When I mailed their customer services, they said that they hadn't broken bikes for a while - so they may / may not have stock depending on what you want.
 
I wouldn't remove one after what happened to Kevin Ash, your insurers could use it as an excuse not to pay out in the event of a claim. Imagine yourself lying in a hospital bed with your GSA in pieces after being knocked off, then a vehicle inspector deems your bike to be non-standard or modified and rejects any claim. I know yours is a 1250 rather than a 1200 but the chassis dynamics are pretty much the same.


Note towards the bottom of the article how the 1200 had a steering damper added as standard equipment in 2014 following the death of Kevin Ash on the launch demo of the water cooled chassis bikes, with other journalists reporting having experienced tank slappers:

"As of model year 2014 the BMW R 1200 GS will be available with the following altered standard features and options:

  • The two modes “Rain” and “Road”, along with ASC as standard.
  • New “Pro” mode with three additional riding modes “Dynamic”, “Enduro” and “Enduro Pro”, including harmonised ASC and ABS as an optional extra.
  • Dynamic ESA can now be ordered separately, independently of the riding modes.
  • The existing five modes are no longer available as an optional extra.
  • Steering damper as standard.
  • White-coated coil springs with the option Dynamic ESA
  • Altered features for the package options “Dynamic Performance”, “Comfort” and “Touring”.
  • All options can now be ordered separately except for the on-board computer Pro.
Whether BMW modified the riding modes software and added the steering damper to correct a 2013 R1200GS actual technical problem that could be associated with a steering wobble that could lead to a tank slapper as it has been speculated by some, and experienced by a few, or whether it was to simply quench the perception of a technical problem as has been speculated, we will never know, I suppose."

I Have a 2013 with no steering damper, i have done over 55000 miles now and has never shaken it's head and I do not ride slow.
So it's up to you but it's not necessary in my mind just another useless item because of a few fools, riding bikes offroad using cruise control.

Thanks… I’m aware, and was ignoring advice to remove.🥱😉 Besides I’ve ridden my old hexhead in environments… deep gravel, sand etc where at times I ‘wish’ I’d had the benefits of a steering damper ‘sketchy’ af 🤪

Understood and absolutely respect the 2014/15”s didn’t have them 👍 However, the geometry… head angle etc of the 1250 gsa is different and although manageable for me ‘thus far’ on road. It can feel like it wants to oscillate when ‘pushing on’ with luggage. tbh I also ride mixed trails where I’d really appreciate the damper being less ornamental on loose surfaces, ruts, rocks etc. Ps Cruise control is disabled in the Enduro modes, (at least) on the later 12 & 1250’s I’ve ridden.

I don't believe that he does (he didn't when I asked him a couple of years ago) however he can sell you a YSS steering damper that will likely be better than the OEM one, be adjustable and be cheaper. He's worth a call for a chat.
 
Thank you 🙏 That’s considerably better than my local dealer and food for thought 👍 Just considering options after mine failed at less than 30k, which is pretty underwhelming 🤔

If it was me I'd be replacing it with the OEM. Think the price of used is high (£140 ish) considering that it could fail again. if the difference was considerably more I may take a chance. but........

On used my thoughts too, depending on how ‘reliable’ these oem units usually are (used = unknown) 🤔
 
In the Marine Engineering world I work in, most hydraulic seals and O rings can be sourced through a hydraulics specialist company/supplier such as Pirtek, not sure how small they go and whether they can supply square section seals etc but I'd wager that a visit to their counter could be worth it if you can strip the old unit down.

As for oil, I'd suspect a light weight fork oil like 5W or 10W would probably suffice.

As a non-adjustable unit I assume it runs a fixed orifice/drilling within the body as the restrictor for the fluid.

It all depends on whether the unit can be disassembled or not, if its pressed together/crimped it is probably scrap.
 
I just looked at my 2019 1250GSA damper and it has a circlip in either end of the cylinder body, suggesting it can be rebuilt. The seal looks like a standard hydraulic rod lip seal, assuming its a standard size (presumably metric) they should be available over the counter somewhere. The oil is probably 5W or 10W shock oil.

Perhaps Denz0 could rebuild it for you, no doubt over time other owners will have the same problem?
