Has anyone tried replacing the stock GS rear Shocker with that from the G310S. It looks like the frame is almost the same for both the bikes and sicne the G310 S has a low height of 785 mm it might help in reducing the height of the GS as well. I undrestand the changes in dynamics and ride quality, but getting my feet on the ground is more important for me. Right now they hang at least three inches over ground on the GS I booked.

That might work OK but you must also raise the forks in the yoke by a similar amount. You might have to alter the side stand as it would be too long - a G310R side stand may fit but they are a bit short anyway, even on the G310R. It's probably easier to cut down (and cheaper!) your own side stand to suit.

I don't know the difference in length between both shockers.
The 310R is definitely shorter ……...
I think you will get a problem raising the front fork.
The handlebar is not that far away and the width of the fork varies once you raise the fork.
Hopefully the margins get your feet on the ground.
Good luck.

Half solutions are bad solutions

Changing the rear shock alone is a very bad choice. It changes the geometry of the bike. Every mechanic will agree. As Glencoeman said, you need to raise the front fork as well, but even this solution is not wise. To lower the bike, you should change both front and rear suspension with approved and tested products. The best solution is offered by Wilbers (Germany) allowing you to chose between 20, 40 and 60mm lowering: complete rear shock and matching front fork springs. The second best is Hyperpro. RalyRaid’s solution: shorter shock, raising front fork, is as expensive as a Wilbers solution and far less recommended. They offer this solution to people, but their main specialty is their complete suspension for real off-road use, which is, indeed, one of a kind. Remember to shorten the side stand!

Why not just buy a G310R? I'm sure you could sell your GS for enough money that the cost of a new bike wouldnt be much more than the cost of a shock swap. Taking away the ground clearance advantage of the GS essentially makes it an R anyway.

Rally Raid has lowering options, check them out.
I bought the tractive suspension low shock from them. at the default setting it came with it was suppose to lower the seat height 10mm. in my case at least it is actually taller LoL.

I had to adjust up the headlight aim, but man does it ever ride so much better. no more pogo or bottoming out.

Although the overal length of the Tractive low shock is shorter than OEM, when the adjuster is set to max, the seat height will be a tad taller than stock because we have designed the Tractive shock, all of them( not just the low vision) to have the correct spring weight for the bike and rider, to give the correct rider sag of about 30% of full stroke.
The OEM shock has a spring that is way too soft for even a light rider, and as you have found, the greatly improved damping, both compression and rebound, will transform the ride.
It is possible to reduce the length of the shock, by means of the locknut on the lower mount, by up to 8mm, this translates to about 24mm reduction in seat height.
Glad you are enjoying the new addition, thanks for your custom.

I was starting to wonder if my bike had come with a bad shock, I have never had a bike that the rear end was so floppy. hit a dip in the road and it would slam into the stop and shoot back up like it had no damping at all. I was slowing down for dips, after a few passes with the new shock I am speeding up for dips! :grin2:

Hi. Just a simple question: I require to lower my G310GS only 15mm. I am interested in to buy the Low Shock RRP 837 from Rally Raid. Looking to reduce the height rear in just 15mm, also slide the forks through up to 15mm to keep the balance of the front and rear.
My weight is light 60 kg.

Hi just a question : I require only reduce in 15mm my G310 GS.
Do you agree in buy and install a Low Shock RRP 837 from Rally Raid reducing the height in 15 mm, and slide the forks through up to 15mm to keep the balance of the front and rear?

Hi. I have a G310 GS too. As I am a short rider, I am considering to buy the Low Shock RRP 837 from Rally Raid. And slide the forks through up to 15mm to keep the balance of the front and rear.
Please tell what you did in your bike and how was the experience.

... I'm so thankful I found this site! I was all set to purchase the Rally Raid low shock until I read this thread. Wilbers -60mm shock lowers the bike to accommodate my inseam and since I'm only doing off road 'lite' ... gives me all of the clearance that I'd ever need. Wilburs unit in CDN $610 (-60mm) and Rally Raid CDN$678 (-10 to -35) ... side stand has been shortened by 25mms

Hi. Please inform what bike you have and what exactly you did. It will help a lot people who is insecure about how to proceed. Thanks in advance.

I have a 2018 G310 GS and need to lower the bike safely as not to compromise handling.
FYI I'm 163cm (5'4"), 55kgs (125lb) with a 74cm (29")inseam
Stock seat height is 835mms and I'm debating between lowering it:
-40mms to 795 (31.25") or
-60 = 775 or (30.5") ... To help decide I'm going to call Wilbers ... I emailed Rally Raid and 3 days no response :-(

Here are the steps and cost from Wilber and Rally Raid ... I checked out other mfgr's and they were all very similar

Step 1. Determine Sag (google for explanation). this is key as it determines how much/little you need to lower the bike
Step 2. Rear Shock - Wilbur as stated above has 3 lowering options -20mm, -40mm and -60mm - $678/CDN
Rally Raid low shock -10mm to -35mm -$678/CDN
Step 3. Front fork spring - If you lower the rear, you must lower the front by the same amount, Wilbur has corresponding springs - $186/CDN
Rally Raid option - Fork kit - $338 (includes preload caps etc. plus instructions on how to adjust for sag)

Cost of the replacing rear shock and front fork springs -
Wilbers $870/CDN + shipping + import duties
Rally Raid $1016/CDN + shipping + import duties

Rally Raid has great videos on how to install the parts ... I'm not a motorcycle mechanic however I have a good friend who restores vintages bikes and has a fully equipped garage. My BMW dealership cautioned me that having them perform the work would be "cost prohibitive" ... I took this to mean I should have bought the far more expensive GS lol

Best of luck

Hi! Thank you very much for very well technical explanation. I am in a similar situation due I am 1. 65 mts and my weight is 60kg.
I already bought and installed the bmw low seat for my BMW G310GS year 2019, but I still require at least, 20mm more to feel better driving my bike.
I am a mechanical engineer and I understand very well that any modification have to be very well proved before to proceed. Otherwise one spend time and money for something that finally could not make you satisfied, secure and happy.

I will appreciate your comments and information when you finally modify your bike. Thanks in advance.

Keep in touch.
Marcelo.

BMW advertise a lower seat option, but I think it's only about 20mm (3/4" in old money) . If you're anywhere near a dealer and they have one it may be worth trying.
It would be a shame to compromise the GS off-road capability not to mention it's looks by dropping all the suspension.

Hi. I am 1.65 mts. I had XR, CR and today also I have CRF 230. A nice and soft Enduro byke. Easy to drive and light.
In the case of my BMW G310GS, I thought in the beginning to have an easy machine to drive. But later on I realized that the weight and high is first me an issue. So, 15 mm down or 20mm less is necessary, to drive with security in my case.
Regarding the low seat installed, is only 15mm, but it counts, makes a difference for me. So that's it.
