5 years since S1KRR DDC has been out and this is THE FIRST IN DEPTH video on how to set the most important parameter for this motorcycle. iB thanks for the upload. Zach thanks for the knowledge brother, you are the TRUTH
Personally feel any dealership selling a new bike should be required to set suspension/sag for free" if the owner requests it prior to leaving the showroom floor....aids in decreasing possible wrecks. Always do suspension/sag and reversal to Moto gp shift on all my bikes, tires matter too, I only rock with Dunlop q3 or q4's or power RS's ....to me it's the safer way to ride especially when your in the twisties hard or going to see track time
The biggest thing nobody seems to tell you in these "sag setup" videos is that all bikes are set up from the factory for riders of approximately 80kg in weight, + or -. If your 2 up riding most of the time, well then of course a sag setup would suit you, unless your both 40kg in weight. This has been a common thing on all adjustable suspension bikes for years. The sag for the road should be approx. 30mm to 40mm. The 30mm sag would be for someone who canyon rides mostly, 35mm both canyon and commute, and 40mm for mostly commuting &/or cruising. Track would be anything from 20mm to 25mm. It all depends on your riding style, weight, and type of bike you ride. Ib's 37.5 is ok for cruising. But Ib smackdowns a lot, so a 30mm set up would be better for him. Its all about setting up the suspension to work in the centre of the springs for the weight your carrying. But the biggest mistake they made in this video is they measured Ib in plain clothes & shoes!!!! WHAAAAAAT!!!!! To set up sag correctly, you need to be weighed in with all your usual riding gear!!!! Thats leathers, boots, helmet, gloves!!! Just a full set of leathers can weigh 7kg, a helmet 1.3kg to 1.8kg, boots & gloves maybe another kilo. This would have brought the sag possibly up to 40mm or more. Way too soft for Ib's riding style. Setting sag is really good guys when you get it right. It changes the whole bike, & experience. It really is great. But only if your more than the 80kg in weight &/or your style of riding is more aggressive. Otherwise, just ride and enjoy! Cheers Groovers ;-)
TheGlobalish: Yeah fair point, I understand that. But if your making a video, wouldn't you prefer it to be truthful? I mean 100% correct? 650 doesn't make vids that are missing things, he's true to his word. Look at it this way. Imagine you didn't know anything about setting sag adjustment & you worshipped 650. You'd believe every word of the vid wouldn't you? I'm not trying to criticise, I'm just very surprised especially coming from a BMW tech, as they are quiet good. Well here in oz anyway. I thought it was a bit messy how the tech did it with numbers all over the place and missing proper weight measurements. You don't really have to do it 100% correctly, as even a 50% job would be still way better than your stock setup (and thats only if your more than 80kg in weight). But at least do it correctly, so the viewers are getting the true low down of how it's done. I just thought the tech took a bit away from 650's creditability by showing a half job really. He's in the correct ball park, but just missing the hot dog & coke! I just wanted to point it out to the young &/or newbie rider/racers that it is done a little differently than what this vid tells you. Also adding, if the tech's missed this little bit, what else has he missed? Torque numbers out? No washers added? Adjustments here & there? Questions to be asked. Just making a point. Cheers groover, safe riding ;-)
For a lot of good information on setting up suspension, I recommend looking up Dave Moss and watching his videos. A lot of great info there also from sag setting, compression, rebound, too tire wear patterns to look for. Great video though. It's a good thing to know how your suspension is setup and what to watch for. You have any track days coming up soon 650ib? I'm from Cincinnati and have been there once last season.
Ive been itching to comment this for a long time now that zach got the measurements the other way round. He put the rear measurements to the front on paper and vice versa
Great job! I prefer put all my gear on to have my exact weight when i ride, and half of the gas tank, because if you set sag with a full tank when you go at reserve you have a difference of 13kg! and the gear (leather) puts another 7 or 8 kg more!
BMW measures their sag different. The “8-12mm” they recommend is the difference between the static sag and the rider sag. You didn’t measure static sag in the back for some reason. Just free sag and rider sag. I think BMW calls it “negative spring displacement”.
That S1000rr in back looks oddly familiar to last seasons giveaway. Was this episode prerecorded by chance? Edit: I didn't watch the video before commenting
Ivan Mesic: No not for this bike. The auto DDC does it when you select different ride modes. But of course you can also manually adjust if you feel like you need to. Of course on a manual suspension bike (all other bikes) you would definitely have to change. Cheers Groover ;-)
The measurement in the manual does not work from static sag ( with the wheels of the ground). They use free sag (without rider) - rider sag( rider plus gear) = sag. That’s why the recommended 6 to 10mm in the manual is a lot less than the sag measured in this vid which starts of from static sag ( being 37 mm). So, one should not try to approach the 6-10mm from static sag, which would mean turning preload way up, screwing up the suspension. Nice vid though!
I noticed that the ignition switch is off in the video when the rear preload adjustment was made. Do you know if this will damage the preload adjuster?
I’m about to pledge is it every month that I’ll be charged 20? Until it’s done can I just pay 500$ to get a bigger chance to win ? But I live in Florida will you ship it?
@650ib the vid is buffering like crazy, not sure why. I'm on an Android device usually your vids don't do this. Did you film in super 4k HD? Just wondering.
Lorenzo Gonzalez seems to be happening in and out on a couple of videos on RUclips this week from a few people I watch and never have problems with so I don't think 650 can do anything ;( to fix I'm starting to call it the RUclips plague cause it's hit or miss but causes every video it hits to buffer every 10-20secs
hello Anyone have a video that show the loose of this Brembo rotor? I have them and I need to know if my loose is normal or not because every mecanic that i know said to me that I've to replace it. Thanks
There are sag and rebound and compression settings for the road and different settings for track work .Also oil weight and air gap in the front forks make a huge difference in your front settings
do you need to do this even if your bike got automatic suspension or they only did this because they change the wheels which i realize while writing this doesnt really make sense asking that last question.. but still why adjust it when the computer supposedly should adjust it for you automatically?
The automatic suspension constantly adjusts your compression and rebound damping, however, your initial sag or ideal preload should be set according to your weight. Once you do that the computer will do its thing. That being said, the question here is whether you need to calibrate the DDC system in your bike after adjusting your preload.
All New Yorkers ride with Air Horns... Even New Yorkers in Atlanta... IB ask Zack how he installed/ attached that Air Horn? I ordered mines as soon as I saw this video...lol
since when do u need to put the bike on stands to set sagg..... its meant to be done from no wight on bike to someone sitting on it..... your measurement will be out because you arnt accounting for the weight of the bike.
650ib why don't you make this bike available for Canadians to win like your boy Campissi does??!!!?! I'm a Patreon of his and would be for you if you let us Canucks win too.
@Arkus - He's got VP9 encoding, some viewers might have to set quality to 480, and avoid the 1080p & 720 at 60fps. Which are tad over kill for slow moving footage.
paolo ippoliti: No its an auto system. The DDC changes when you select different ride modes for you. But if you feel the need for more dampening, you can adjust it manually via the dash. Its very easy. Most times you don't need to do anything. Its only when you go track riding, that's when you do feel differences in the changes. Cheers Groover ;-)
This video is very misleading. If you take the time to read the BMW owners' manual properly, you will find the adjustments are made with reference to the static sag with the bike sitting on its sidestand and not the free sag. The figure of 8-12mm at the rear is the difference between the static position for the bike on its side stand vs the sag with the rider seated on the bike, upright and in the riding position with the ignition switched on. This guy seems to think the rear spring would need cranking right up in order to achieve BMW's figure of 8-12mm because he is referencing his measurements against the free sag . . .duh!!!! He has the same misunderstanding with the front forks where BMW use the same "static" reference point for adjustments. From the factory, these bikes are set up with the correct preload for an 85kg rider. An interesting video in some respects but incorrect and misleading, given the tech clearly doesn't really understand what he is doing and can't average 77 & 78 without a calculator . . . . . . One reason I do all my own maintenance and won't let a "qualified" mechanic anywhere near my bike!!
ybliga you are incorrect sir. I just read the manual agin and the measurement is done with the help of a third person and rider on the bike. I do agree those sound like free sag numbers. It may be a bad translation. That is why I said to stick with the normal numbers of 25mm for track and 35 for street. Thanks for watching.
I honestly don't have a clue what you're trying to say but you're quite wrong!! There is no mention of free sag in the manual - anywhere in the manual!!I was wrong on one count - the static sag is measured with the bike held upright, minus rider and not on the sidestand. The rider's weight is now applied and the negative spring displacement is measured as the difference between the two measured values. This should be 10-15mm front and 8-12mm rear. The bike is set from the factory with the correct preload for an 85kg rider but in order to attain the above values, the preload needs increasing for heavier riders. At no point in the manual is any reference made to the free sag - it isn't needed or used when setting up for the road. You made the statement that the rear shock would have to be really cranked up in order to attain a sag of 8-12mm but it doesn't. I am 200KGs and I can achieve a negative spring displacement of 10mm with only a modest adjustment. The 8-12mm is the displacement with reference to the static sag AND NOT THE FREE SAG as you stated. There may be a variety of ways in which the suspension on these bikes can be adjusted and in particular for track use. That said, your technique is inconsistent with the instructions in the manual and it is important that riders understand that your guidance is incorrect if they want to adjust their settings as per the official BMW-approved technique.
Ybliga. I red the manual the way you did when I set mine up. Problem is; when you increase preload, both those measurements will go up, and the difference will be pretty much the same. Doesn't make any sense to me, so Im thinking maybe there's a mistake in the manual...
janolewilhelmsen, Thank you for that remark - it is most helpful. I have owned my 2015 S1k since new and the suspension is still on factory settings for an 85KG rider. I watched this video as I thought it is about time I set my preload for my weight of approx. 100KGs. I have read the manual several times now and did wonder if with each increase in preload, the static measurement would also increase and so, as you say, I would have ended up increasing and increasing preload and never reach a negative displacement of 10-15mm front and 8-12mm rear but in any event the bike, either with or without rider, would inevitably sit significantly higher. With this in mind, perhaps the following is the intended translation. . . . . . . . The bike is set for an 85KG rider from the factory and BMW intend that when setting preload, the static measurement required should be the single value taken from the bike whilst set at factory preload. Given a heavier rider, If preload is now increased until the negative spring displacement is as specified BUT with reference to this one specific static measurement and NOT the gradually increasing value, the bike would end up with the same ride height, regardless of rider weight and each bike will settle with the suspension being compressed down by the same amount . . . . the negative spring displacement will be different in each case from the static measurement for each preload setting but will be 10-15mm front and 8-12mm rear from the Factory-set static measurement - my money is on this explanation. It makes far more sense to me and would also give the same negative spring displacement for all bikes from the free sag figure - the problem is, BMW don't specify this in the 2015 manual. Thanks again for your comment as your experience should prevent owners from going down the same route and having to crank up their preload excessively. I suspect the pre-2015 bikes might have had spring displacement figures referenced from the free sag measurement which is why this video is otherwise so confusing? . . . .
Full carbon would get smoked...Jaret is a virgin when it comes to smackdowns and IB would have the s1000rr prepped by Zack and his better resources to destroy that thing...being light weight ain't everything...skill, tuner, bike builder all come into the equation as well
Not to bag on this video but there was minimal information given have to agree w/ Tdiesel2679 Dave Moss is the man if you want clear cut information on how to set up your bike look for him on RUclips he has a lot of free useful info.
total joke he measured and marked the sag on the wrong end when he wrote them down ,, front/rear, then said 103 at front it measured 115 then he said just what i thought , total b/s ,,
jimmy hope I still get flustered on camera and what I think in my head does not always make it out correctly. Sorry. I did totally screw up that paper at the end I re-wrote it. Haven’t had a chance to see if it made the final edit though.
The measurement in the manual does not work from static sag ( with the wheels of the ground). They use free sag (without rider) - rider sag( rider plus gear) = sag. That’s why the recommended 6 to 10mm in the manual is a lot less than the sag measured in this vid which starts of from static sag ( being 37 mm). So, one should not try to approach the 6-10mm from static sag, which would mean turning preload way up, screwing up the suspension. Nice vid though!

I Totally agree, it should be mandatory for suspension sag to be set up for new owners.
Agreed. Tbh i foolishly thought with all the new technologies.....this was an old school bike exercise..This vid is old....feeling a lil STUPID😒😒😒😒😒
ib You have no idea how much I LOVE the tone in your voice on opening of these rebuild series. like always enjoyed this one as well. cheers
The 8-12 mm difference in the manual is the difference between static sag and rider sag. Not the extended sag.
Zack is the man! I need him to put his expertise on my busa bro!
You're supposed to do measurements in full gear if you want the best results. Dave Moss is a master when it comes to this stuff.
Ghost true I said this but we did not show it

U adjust the front and rear suspension but u don't show why or the new measurements. :(
BMW manual measurement is correct, to get there measurement they subtract the rider weight from the bike only weight to come up with there figures
Put a mark on your socket then you know how many turns you have done
It wont save the settings that i put in the front and rear. As soon as i get moving the settings just return to zero

8-12mm in the rear sounds more like a free sag number.
no, see my explanation above
Jamie SV650 I agree but I just looked back in owners manual and it is with rider on. That is why we used normal numbers instead.
Thanks for the link
But... the calibration of DDC? You forget it?
paolo ippoliti: No its an auto system. The DDC changes when you select different ride modes for you. But if you feel the need for more dampening, you can adjust it manually via the dash.

This video is very misleading.

janolewilhelmsen, Thank you for that remark - it is most helpful. I have owned my 2015 S1k since new and the suspension is still on factory settings for an 85KG rider. I watched this video as I thought it is about time I set my preload for my weight of approx. 100KGs. I have read the manual several times now and did wonder if with each increase in preload, the static measurement would also increase and so, as you say, I would have ended up increasing and increasing preload and never reach a negative displacement of 10-15mm front and 8-12mm rear but in any event the bike, either with or without rider, would inevitably sit significantly higher. With this in mind, perhaps the following is the intended translation. . . . . . . . The bike is set for an 85KG rider from the factory and BMW intend that when setting preload, the static measurement required should be the single value taken from the bike whilst set at factory preload. Given a heavier rider, If preload is now increased until the negative spring displacement is as specified BUT with reference to this one specific static measurement and NOT the gradually increasing value, the bike would end up with the same ride height, regardless of rider weight and each bike will settle with the suspension being compressed down by the same amount . . . . the negative spring displacement will be different in each case from the static measurement for each preload setting but will be 10-15mm front and 8-12mm rear from the Factory-set static measurement - my money is on this explanation. It makes far more sense to me and would also give the same negative spring displacement for all bikes from the free sag figure - the problem is, BMW don't specify this in the 2015 manual. Thanks again for your comment as your experience should prevent owners from going down the same route and having to crank up their preload excessively. I suspect the pre-2015 bikes might have had spring displacement figures referenced from the free sag measurement which is why this video is otherwise so confusing? . . . .
Nice bike
That’s my love 😍
I don't know who this guy is or what he thinks he knows but Ib650 you need to watch the Dave Moss.
Sorry 650ib
Race the full carbon panigale
Full carbon would get smoked...Jaret is a virgin when it comes to smackdowns and IB would have the s1000rr prepped by Zack and his better resources to destroy that thing...being light weight ain't everything...skill, tuner, bike builder all come into the equation as well
I want this bike please
Not to bag on this video but there was minimal information given have to agree w/ Tdiesel2679 Dave Moss is the man if you want clear cut information on how to set up your bike look for him on RUclips he has a lot of free useful info.
total joke he measured and marked the sag on the wrong end when he wrote them down ,, front/rear, then said 103 at front it measured 115 then he said just what i thought , total b/s ,,
jimmy hope I still get flustered on camera and what I think in my head does not always make it out correctly. Sorry. I did totally screw up that paper at the end I re-wrote it. Haven’t had a chance to see if it made the final edit though.
@@Skr-gb4hk you're a beast.
Sent you a PM on instagram 650ib - keep up the amazing content! 🤘cheers
Dont think math was his thing
salam from malaysia.. 😊😊
Salaams Bro 👍💪
Amm,.........ib,...........this video is only buffering for some reason, can't get to watch it.
Hayden Grant same here
Can't wait til BMW gets rid of that ugly exhaust!
TheGlobalish that explains a lot nothing BMW could do about it I guess. I always wondered why they put this crap on there and now I know, thanks!
First to do Thumbs DOWN!
The measurement in the manual does not work from static sag ( with the wheels of the ground). They use free sag (without rider) - rider sag( rider plus gear) = sag. That’s why the recommended 6 to 10mm in the manual is a lot less than the sag measured in this vid which starts of from static sag ( being 37 mm). So, one should not try to approach the 6-10mm from static sag, which would mean turning preload way up, screwing up the suspension. Nice vid though!
Badass looking! Peace
