i'm about 90kg and can bottom my forks without trying very hard. without spending a lot of money the first thing you could try is raise the oil level in the forks. I raised mine by 5mm better but not there yet. so maybe raise it 10mm. the other thing would be to make a couple of preload spacers. to get an idea how big to make them measure your static rider sag then subtract what preload setting you should be at. that'll give a good start point for the spacer size. but i suspect that this may put to much preload on the springs and may actually negatively effect suspension. the next step would be to get new spring in a spring rate for you weight and riding style. and of course the there is alway getting new cartridges and springs. this can be with or without esa as both types are available. my personal choice was to dump the electronics and go with full manual adjust cartridges and springs built for my weight and riding style.

Interesting too. I believe I'm close to, or at bottoming out at the front (sometimes a weird feeling). Should have tried the tiewrap method, but have traded it in against the 2020 model. I'm 80kg, say 90 with gear. 190cm (6'4"), I sit 40mm higher on a custom seat compared to standard. On going into a turn the rear wheel moves, not enough weight on it.

Yeah I am about 90KG and I get horrific front tyre wear, running a softer front sports tyre just makes it even worse. The shoulder of the tyre wears really badly. It can be down to the wear bars on the sides before in the middle.

Hi Addelaat,

I too have felt that the front suspension is bordering on dangerous.

I bought my bike last October and on the journey home was surprised by how ‘comfortable’ the bike was. Especially since all the reviews I had read reckoned that it was on the ‘firm’ side.

After a few rides I began to suspect that something was amiss; it feels vague and soft, and mid corner can wallow about. I too fitted a cable tie and it bottoms out very easily (I’m about 90 kg).

There then followed a trip to a suspension specialist, 2 visits to my local dealer and an extended visit to the supplying dealer. All without success. The specialist said that he could not comment on the current set-up as he did not know what the manufaturer's settings should be and BMW do not publish them. The three visits to the dealers came back negative as they said that the suspension showed no faults and was within BMW’s parameters.

I did consider ditching the standard ESA suspension and have it replaced by a specialist, but this would cost around £2k, produce error symbols on the dash and might cause problems with my warranty.

I have taken the view that rather than spending on replacement suspension, I’m best taking the hit and trading it in for something else.

I own a few other bikes and whilst I do not consider myself to be a Martini Rossi, I’m reasonably competent. Recently, I went out with a mate, who is a very competent rider and whose judgement I trust; we swapped bikes and I followed him on his ZZR1400 and was amazed at how easy it was to keep up with him. When we stopped he immediately said that he felt that there was something seriously wrong with the bike.

I also let another friend, who is a bike instructor ride the bike. Without any prompting he said that it would be an 11 out of 10, but for the suspension!

I should point out that mine is the lowered version and I was beginning to consider that it is compromised as a result (since most owners seem to be very happy with their XRs).

Long story short - I’ve decided to run it over the winter and will probably chop it in for something else later in the year. It will mean losing a few quid, but I like you think that is dangerous. Trouble is, what do I get? I don’t want any more GS’s - perhaps the new Triumph 900.

I am going to fit a cable tie now :-)

I don't feel like its dangerous at all I also run it with the forks dropped through the yokes a bit to make it turn faster.

But I do notice bad front tyre wear.

Hello Falernia

Nice to hear from you that you have the same experience as me.
I also have some experience with riding sports motorbikes and have participated in motorcycle racing competitions in the past. Now that I am a little older and have a larger belly, it is no longer possible to drive a sports motor such as a BMW S1000RR.

My dealer has also been instructed via BMW Netherlands to read the suspension from which no errors are found.
BMW does not want to come to me in any form to remedy this dangerous system. In fact: if I change something about the configuration of the motorcycle, the warranty will be voided.

My dealer does not want to take the bike back but shares my opinion.
I think the BMW S1000XR is a nice bike when it comes to the seating position, engine power, navigation options etc. Only the suspension must be adjustable and muts more better.

What am I going to do to make it better.
I have looked around at what there is .

Öhlins has nothing.

Tractive is the manufacturer of the ESA, this system only controls the rebound at the front, no spring pre-tension and no compression settings are possible.
The rear damper is only controlled by the rebound and pre-tensioning by preset force by the ESA system.
The compression is not regulated.

Wilbers only has different springs for the front, which means that the stiffness can change but not the hydraulic compression.
At the backside they are the only ones who can supply a damper that uses the ESA system whereby the spring can be adjusted to the rider's weight, damping and pre-tensioning are controlled via the ESA system and the low and high compression can be adjusted manually .

Adreani Missano has the solution for the front.
Manually adjustable cardridge. Left fork for damping - Right fork for compression.
Springs for the right weight and on both legs pre-tension setting possible.
And they have the solution for the error message by connecting an electronic attachment so that no error messages occur.

What did I order:
- Wilbers rear damper shock - 644 WESA Dynamic Comfort with spring
- Adreani Missano fork dampers - CARTRIDGE BMW XR 1000 EC - EVO - REG SKU: 105 / W07E
- Adreani Missano electronic part - CAVO INGANNATORE ESA TTX49 X BM146 - BM147 - BM148 - BM149  SKU: 01.L13.001

Hopefully this is the right decision.
 
To be continued.

falernia, interesting you say yours is soft and the lowered version. My XR is std height and it is soft, a tad wallowy at times (in road, better in dynamic but still a bit soft, certainly not the sports bike handling as suggested on all the reviews etc.) but I wound not say dangerous in any way, but my mates lowered XR is much stiffer / harsher ride on the same settings. I was thinking the lowered bikes were maybe stiffer due to less travel but things I'm reading suggest just a vast difference between bikes, both low and std height, for no apparent reason.

Indeed very interesting stuff,

mine is also a tad soft in road mode, but I have never been able to bottom it out and I drive in Belgium, with notoriously bad roads.
I weigh approximately 112 kg with gear and about 6'3" (192 cm) tall, so there really must be some huge differences in the way the suspension is set up on different  bikes iif some of you are experiencing these issues. Mine is not lowered.

All the best,

Remo

 :028:  Holy moly you did some work on this. Going to fit cable ties too on the new one, can't really add miles to mine given the trade in value i have

I'm dumping the esa for full manual. What I'm getting is GP Suspension cartridges (preload, compression and rebound adjustments) tuned to my weight and riding style. For the rear I went with Nitron pro with remote preload adjuster (use this a least twice a week for bike night or other rides with the wife). Several suspension shops said they could build whatever I needed but would need the bike so they could measure things properly. Pretty much they could build whatever brand you wanted Ohlins, Penske, Nitron, Racetech whatever.

Then come the part of error codes and lights. No one really seems to know much about them. Andreani does list two dongles for the XR presumably this prevent the error codes and lights. They list a single and a two piece. As of yet I can't find anyone that can actually confirm that they work or have used them but ordered them just the same. Currently just waiting for the parts.
