Is it the R1200 GS, or the R 1200GS, or the R1200GS, or the R 1200 GS? Dunno. But it's the gold standard for Adventure Touring bikes. Only the Germans could invent a front shock.
Mình rất thích xem các video về kỹ thuật , có phụ đề tiếng Việt Nam thì hay biết mấy
Totally!
Would in not be easier to adjust front shock with spanner wrench with bike on center stand (bike weight off shock spring) ?
Yes, it would be easier, but normally with the side stand there is enough tension removed for the shock preload to be changed.
3500 bikes a year? That's 10 bikes a day, seven days a week, 52 weeks a year. I wish I had that energy.
Dave Williams, editor, replying here. Actually it's an average of 25 bikes per tuning event, about 140 events per year. Back in the 00's there were years where he did over 250 events a year (he spent 15 years living in his truck, literally). I have filmed him tune over 40 bikes in one event (and recently). He's 60 years old now. Like any good motorcycle, we're hoping to get another 10 years out of him. Apprentices needed (if you've got the huevos).
Mr Williams, I liked the change done on video especially the thumbnail part...
when I get see your myth about suspension with newer points..
Dave Williams, editor, replying here. Thx much. As soon as I find another suspension myth I'll do a video about it for sure.
A doubt/clarification;
the front end was a design was from Hossack, done on BMvee on K100s for better stability n lesser dive, sometime later these conversions were shipped to Germany and were tested by TUV Germany and were certified for using it on German roads, BMvee got wind of this conversion happening on their motorcycle n some reason decided to make this their OEM.
my guess is because they (BMvee)didn't want to know has Half n Half motorcycle...;)
Great information and thank you for sharing!!!!
The Hossack is the DuoLever System this is the Telelever nothing to do with the Hossack system
In the dirt stream or no, have pride in your ride and clean her already imho
I am not an engineer, but my guess is that germans decided to put a shock there to deal with the weight? Additionally riders very often put big tank bags and other equipment in the front too.
The telelever was made to prevent fork dive while braking and maintain the geometry.
On a normal fork however, a good rider can take advantage of the geometry change to turn the bike quicker. Probably not applicable to the big GS with it's intended use.
Great reply Carlos and note that this also adds to stability with a big bike when off road as you as a rider are not pitching back and forth with terrain changes and bumps. That in turn saves your energy :)
I binge watched all Dave Moss videos here trying to learn as much as possible since I'm repurposing old KTM Duke to "adventure" bike for permanent setup for pillon and cargo. That means from 73kg to 153 kg which in current stock setup is unrideable despite changing preload and dampening as per manual.
I know I need atleast to change the springs. So I'm thinking theoreticaly can it be reverse-engineered in such a way that you get precise number for a spring rate. For instance if I load the bike with driver and measure sag then I add cargo and pillion and remeasure sag and get let's say 50 mm additional sag. Is it possible to calculate in reverse that 50 mm additional sag on a 70N/mm spring with 80 kg of additional cargo requires some number of Newtons to spring rate to return sag to correct number?
Mostly it's the front that confuses me especially since it has 65-90N progressive spring and that complicates things even more what to do. What do you think guys does that make any sense at all?
old Duke, what model is it?
being curious to know..
Take a look at total sag with pillion and luggage first. See what sag is fully loaded for the shock. If your stock rate is 70nm and you have 100mm of sag with current preload settings, then consider a 90nm spring with 15mm of preload added to the spring when it is installed (ie 200mm in the box, 185mm on the shock). You have to fix the shock first. Once shock sag has been set, find your own settings, do not use the manual. Then take a look at fork springs in the .8 to .9 range.
If Dave’s having trouble, it’s probably going to be impossible for me.
Hello. Nice video. For off road use which way you turn the front suspension to increase the length of the spring. To the left or to the right??
Hello and thank you. Left makes the spring longer.
watch your back lifting those mate. cheers.
People rarely change the fork oil on a GS/GSA, and don't get the suspension setup to suit them.
It's like buying 60% of a bike.
That's cause the fork oil is just that.... oil. No damping done, just lubes the bushings........ Dunno what you mean by 60%
@@alm4132 why buy a bike and not get it setup for you, rather than a generic, one size fits nobody ?
I am aware what the telelever fork oil does, it isn't a difficult task to change the oil, but it rarely gets done.

Hey Dave great videos and amazing knowledge sharing..
I own a 2019 1250 gsa hp, running on michelin anakee adv tyres for the past 8000 kms.
My front tyre has shown major signs of wear only frm the right side( throttle hand side). I primarily ride on tarmac with two up most of the times. Need help on what all culd be the reasons pls before i go for a tyre change.
Wuld appreciate ur guidance and feedback..
Cheers frm India
If you happen to be in Istanbul, stop by MOTOSENKRON and have all the shock absorbers of BMW motorcycles repaired with a one-year warranty, very cheap 250 euros.
Hi Dave. I’ve been meaning to ask you for quite some time already but always forgot. What type of C-spanner that you used when you adjust the front spring of the GS in this video? Been trying to find one same as yours. A good video as always. I learned a lot from your video. Thank you for all the knowledge shared.

@@catalystreactionsbw thank you very much sir. Looking forward to learn more about suspension tuning with you and the team.
I have the same bike, except with esa (Electronic shock adjustment), when setting the Esa from "normal" to "sport" it adjust with shocks. Also the bike is bumping in the front on a perfectly flat road. Any idea what it could be? Thank you in advanced. Regards from Holland :-)
Take a look at travel used front and rear. That will give you some insight into "why?" If not enough travel, shock preload needs to be less. Ideal is 3-4mm from the bottom out bumper.
Hi Dave can you adjust these setting with ESA suspension?
Yup, broken pelvis here...don't do it, not fun!
