Fitting S1000RR forks to the nineT

Picked up a set of forks from a 2014 for a good price. The one problem is that the speed sensor clamp does not fit into the space it is supposed to go into. The holes line up but it doesn't sit flush. It looks like with a small amount of grinding of the bracket it will fit but I wanted to know if anyone had done this mod and what their solution was. Thanks

what are your thoughts on the new forks?
Great question! Happy to share my early impressions. Mind you I have zero suspension sophistication or point of reference. If we could ride well set up stock, S100RR, Wilbers and Ohlins side by side, in succession I'd know something. But I a coming from a very basic non-adjustable stock fork with 6k of easy miles on the original BMW 7.5w fluid and comparing to a slightly upgraded similar model with three times the adjustability and brand new BMW 11.5w fluid (albeit it's probably the same practical viscosity as I believe the difference is based on a mfg change). Add to that that I am no lightweight at 250#+ so that factors into any discussion of 'performance'.

First impressions are noted in post #99 just above yours. Since that the forks have loosenes a bit and thay have been worked. I am breaking in a new front tire at the same time so some more aggressive behavior has been delayed. BUt after playing a bit with the preload and two damping adjustments I do believe that A) they are far better suited to my weight than the otriginals and B) the general front end related ride is noticeably improved with less hard edged jarring from that end of things. It does seem to roll things like frost humps and bridge joints a lot better than stock and I find them more comfortable overall. Thhet are stiffer in most situations, whether just manually bouncing the front end in the darage to test to less diving in harder breaking. There is stii more to be learned once the front tire is fully able to throw in to cornering I'll know if that's better. The stock felt a tad wallowy to me. But I never hated the stock and could have coexisted with them just fine. But I believe the S1000RR are just better in every way because of their adjustability. I'd also think that an Ohlins or Wilbers would be markedly better than these in teh same way as a lot of S1000RR owners scrap these for those pretty quickly. But fro my casual riding I'd expect these will suit me moe than fine at a quarter to third of those two brands. I can live with that.

Thanks for the insight and great job on the oil change. That looks a bit too much beyond my abilities, I was hoping S1000RR forks would be an easy drop in, but I guess you never know the true condition of the old oil if they've had some miles on them. The stockers are definitely too soft and I hate the dive upon braking you get from them.

These probably could have been as I think they were 500 mile take-offs and the oil looked really good. I just think if you're that far into a disasembly it's not that much more work to make sure you know you're baseline before you put everything back together. I don't thik you'd want to purchase anything used and not at the minimum do a fluid change. I am sure a local shop woudl knock that out for a hundred bucks plus teh cost of oil. Not a deal breaker. There are a couple good looking sets on eBay currently, one with 'Traxxion' cartridges.

Ok so after perusing throughout this I have some questions that you guys can hopefully answer.
I have a 2017 pure. I am looking tondo the s1000rr suspension upgrade. I’m looking for what I need to do this.

- I think I understand I need a more lower triple, can I use the s1000 one or do I need to get an r9t classic one?

- the top triple, am I going to need to swap these out? Again can I use the s1000 or do I need the r9t classic?

  • do I need to swap brake lines or anything else aside from the calipers?
  • Are the pads interchangeable between the pure brembo calipers and the s1000 brembo calipers?

- what else do I need?

So far this is what I’ve got in my cart
  • front forks low km $800 S1000rr
  • Mint low km Caliper set mounting bolts & pads $500 S1000rr
  • Lower triple & stem $700 S1000rr

I ended up going the new ohlins route as finding good forks at the time was hard. I looked for maybe 6 months. You should be able to find mint calipers for around $200. That's what I paid with shipping. Yes you will need need brake pads. Brake lines don't need to be replaced. You will also need an axle, I paid like $100. New front bearings and cover. If you can't find a used triple trees I would suggest buying from over seas. I bought from kfm-motorraeder.de and saved a couple hundred off the cost vs a US dealer and saved on taxes too. Total on new triple trees were $675.
This past week I swapped to the s1000rr forks on my 2014 classic.

Purchased a used set on eBay from a 2014 s1000rr In decent condition, the forks were straight however, the oil seals were worn along with the wipers and was leaking oil on the Stancions.

I wanted to make sure that everything was in decent shape to be reused so I had GP suspensions rebuild them for me. They are local to me so it was very convenient to drop them off and pick it up.

GP suspensions rebuilt them, with all new SKF (standard non green) Oil seals and wipers, verified that the forks are true, and filled it with the recommended 5wt oil for my weight (180lbs)

The install as discussed here was straight forward and a direct swap with zero drama. As mentioned, you do need to modify the ABS wheels speed sensor bracket to fit on the s1000rr fork. A few minutes with the Dremel and some black spray paint and you are good to go.

initial impressions is that it is a huge improvement over stock,spring rates are similar but the biggest difference is how much more controlled the dampening is. I live in SoCal and ride through a range of road conditions from smooth paved canyon roads to Rough uneven freeways. With compression at 5 and rebound at 6 it was a little TOO stiff for the roads around me so I backed the rebound and compression to 4 and I felt that it’s a good balance between comfort and confidence in the corners.

I feel that these settings will probably change, as the fork oil wears and temperature gets hotter but overall it is a worth it upgrade if you do not want to go the Andreani or Ohlins route.

Nice. I can confirm a couple things that you noticed. 1) they are probably stiffer overall that you expected and you'll probably find you'll need less preload and other damping that you'd expect, especially at your weight. and 2) they will soften a bit once the oil gets worked some. Mine were pretty unforgiving at first with the standard BMW oil but relaxed pretty quickly once everything settled they are very manageable.

Internals, cartridges, forks 2017, S1000RR can it be fitted to 2014 Roadster.

Hi Fellow Riders,

I have been looking around on Ebay and some other places for used fork cartridges and internals from a S1000RR model year 2014 and up. This option comes to play for me simply because of the cost. Also came across 2017 and up R9T model internals, which even though I know aren't the greatest still are adjustable. Also allot more accessible in terms of cost. Since I know people have done it, fitted S1000RR internals in to my bikes forks without any issues. I guess it's something that would really upgrade 2014 bikes suspension. Hope there's someone here with experience in this sort of thing and could help me with a step by step procedure? Also I've been wondering can the same thing be done with 2017 R9T cartridges, do they fit easily and straight forward in to 2014 bikes forks? Surprisingly I found allot of post 2014, like 2017 and up S1000RR internals which include dynamic ESA. Naturally I started wondering if even this could somehow be fitted to my 9T, together then maybe with the rear shock... I know the underlying of those two bikes are similar.

Please guys if anyone has any knowledge and experience with this sort of thing let me know here when you get around to it.

Cheers Riders 😉☻😉☻

SO I am wondering these S1000RR 2014 model forks are Gen 1 or 2, 3¿ BEcause all I can find on EBay are gen 3 Internals or fork season which already have electronic dynamic ESA system. So how does one install that on to a 2014 classic R9T?
only the forks from 2009-2014 S1000RR will be a direct plug and play for the 14+ R9T. As those forks do not have the DDC electronics in it. It’s a lot of work and piecing together just trying to swap fork internals into your current forks. At that point, you might as well go aftermarket (ohlins, andriani, GP suspensions, etc...)

Alternatively, if you can find non DDC equipped s1000rr from the later years that will work too. They have black fork legs. But I don’t think they built a lot of the s1000rr without the DDC.

There are plenty of options for the all years R9T classic forks but the cheapest way to improve handling is using compatible s1000rr forks. You just have to keep looking, it took me a while to find a decent pair at a price I was happy with.

Tnx Fugitive, this is more less exactly what I was hoping to read. It all makes sense now.

I believe there’s a pair of S1000rr 2014 forks right now on EBay, the price is a little high though... So I am gonna try to drive it down a bit. They have a red valve, bolt on just one of the fork legs, right? So I guess you are very happy with performance of those forks?
Both Forks should have the Compression adjustment on the bottom.

Yes, overall compared to the stock 2014 classic front forks I am very happy with the performance. I do a lot more street touring and a little bit of canyons and I am able to adjust it to my riding style. It is comfortable on longer rides and isnt as jarring on the highways. For the money its the best performance gain, unless you are more of an advanced rider looking to get more out of the bike.

I know it’s subjective but what is a set of used 2009-2014 RR forks in decent shape worth?

I paid around $650.00 for mine, on eBay. Great condition, low mileage take offs (as far as I can tell). I did a fluid change so that's a small added cost. Sold my perfect condition stock units for around $400. They could be worth a bit more in the right situation.

Hi Nervous,

I don’t have this kind of money for the pair of forks! But I found fork internals for just 150€. Cartridges are from a 2014 S1000R, now I am not sure how great a solution they would be?
I fitted fork internals from a 2010 RR, yes they wil fit but at the time I did not notice that the end of the forks at the bottom are a different fit. The R Nine as about an inch and a half long shaft which a bolt passes through the fork lowers and secures the fork internals. The RR fork internals do not have this extension which means that these internals sit an in inch or so higher in the legs. None of these things got noticed at the time due to me thinking this is an east peasy job and what's all the fuss about changing fork cartridges etc. I had put the fork oil and capacity that the person who I bought the fork internals from recommended. At first I thought everything was OK, the ride was firmer with no brake dive, it was only when I went on a spirited ride that a couple of things came to light. The ride was way too firm for the roads that I tend to ride on but the biggest problem was running wide into fast corners....extremely dangerous especially when a car is coming the other way. The problem was due to the RR forks sitting too high in the fork tubes, can't see why the R9 tubes would be different to the RR tubes but there is a difference. This causes the RR forks to be under a lot of preload which I could not dial out and the cause of my bike running wide. I have reverted back to the original internals but using 15w fork oil which to me makes for a better ride... I did take photos of the difference between the fork ends but I deleted them from my iPhone ..The ends of the forks cannot be changed due to the ends on the R9 being crimped on ..
So Kenko, are you still claiming the same thing the S1000RR fork internals can’t really be fitted to the R nine T fork tubes?
I posted around last Christmas Dave about fitting RR fork internals. Due to the Bottom fitting on the RR forks being about 60 mm longer, this puts the spring under too much preload which cannot be dialled out. The 9 T bottoms cannot be swapped over due to them being pressed onto the metal fork internals. I cannot see that due to the 9T being heavier then the RR that this would compromise the forks. I often ride my 17 stone nephews S1000RR which is set up for him. The bike handles fine to me and I am 13 stone. For around £300 this as been the best and most noticeable improvement on any bike that I have ever modded in all my years riding bikes.
Kenko, and what about changing and using different springs for the S1000RR internals, I have a feeling you gave up to easy.
He probably gave up a long time ago. He hasn't even logged into this forum in the last 10 months.

No not so far mate.
  • Ive purchased the forks and calipers.
  • ive been told the triple tree can be machined out to accept the diameter of the s1000 forks in leu of replacing them.
  • Im not clear on what front axel i need though, s1000?
