Suspension Setup Tips with Dave Moss

World renowned suspension tuner Dave Moss shows you his take on the Slacker Digital Sag Scale by Motool. I think he likes it:)

[@88Heckenlively]

This guy tuned/dialed in my stock suspension on my '08 KTM Super Duke 990 at a track day at Sonoma Raceway. It took him maybe 2 minutes. Totally transformed the bike and I was easily 5 seconds faster a lap the next session. I was blown away by the stability. BEST $20 I EVER SPENT.

[@SlackerUSA]

No doubt, Dave is amazing! Once you have ridden a properly setup bike you can never go back:)

[@233kosta]

​@@SlackerUSAHear hear! Even with just the correct rear preload adjustment (can't touch anything else) it transformed the handling!

Thanks Mr Moss..., you've got the best technical content out there...

[@mikaeljonsson2078]

Interesting tool, especially when there is no assistant with a tape measure around :) I work as mechanical engineer at Ohlins Racing, and can vouch for his statement that sag adjustment is the very first step that should be done if you want to get the most performance out of your suspension(and ultimately faster lap times). There also some misconseptions out there what the preload does. Some people believe that the spring will become stiffer by adding preload, but that is not the case. Preload only changes the sag or "ride height", that's all it does. The spring has the same spring rate (Newton/mm) throughout the whole stroke (unless you have progressive springs, which is not very common on sport bikes).

[@SlackerUSA]

Hi Mikael, Good point, thank you for the input! I think alot of people just don't have enough time to learn about this stuff so it is easy for others to spread bad information. We need more people like you that are willing to add to the conversation rather than start their own! If you see Chris Nilsson (Stockholm) if he is back from paternity leave!

[@mikaeljonsson2078]

@@SlackerUSA Ahh, so you know Cristopher? I wouldn't say I know him very well, since we never have worked in the same department, but I have talked to him briefly. I'm with the MC OEM dept. since 2013, and he is with the marketing dept. in the north end of the Ohlins building. I will tell him you said hi next time I see him :) And regarding suspension setup, and analyzing/solving mysterious chassis behavior, there is a lot more to be said. Although I've worked at Ohlins for more than 8 years, I still learn new things almost daily, and there is always things to improve, so I have never seen myself as an "expert". But I'm willing to share my accumulated knowledge to anyone who is interested. It's also in the best interest of Ohlins that our customers knows what to do with all the knobs and dials, so they make full use of their investment.

[@ewalt5501]

Mikael Jonsson what about just regular street riding? Work ,home ,school?

[@calculusmetal]

But if F=Kx, doesn't that mean that as you compress the spring (more preload), then the minimum force to compress the spring further, is now higher? That's why commoners say it is now "stiffer", because it is?

[@tlalexander3]

Hey Dave! I have a 2019 Yamaha R3 that I just bought as my first motorcycle (other than dirtbikes). I am having a hard time getting the rear spring preload set to a decent amount. I have played with settings 3 through the softest/less compressed setting but the ride is pretty firm on the cracks in the road. At one point I had to stand up yesterday because it felt like I could get bucked off. I weigh less than most riders (150 lbs). Also, I have the dunlop sportmax gpr 300f tires on it that are brand new. I am running 29 psi in the front and 36 psi rear like it says on the swingarm. Also, I thought it was odd, but I am only getting around 15% compression of the rear spring when I sit on it and it is set on the weakest setting. I also do not see any static sag when I pick the bike up on the weakest setting or any setting for that matter.

[@rocknraptor3195]

If you have no static its too much pre load! I push my rear down let it rebound then lift up to check for sag. Also that tire pressure is way too high!! Mine says the same but 36 is a lot & will only get higher the more you ride from heat. Friction makes heat plus road temp! As seasons change you'll need to adjust the psi, where i live in the south psi can increase by about 10 with aggressive driving in the summer. Ive been riding on decent days recently about 28 & 30 psi, which only increases, the warmer the air temp the warmer the road & the more increase your tire pressure will have! In warmer weather & summer I'll drop to 26 & 28 & maybe more. All bikes & all tires are different! I weigh not much more than you & my preload is almost at the maximum adjustment, if you have too take it to the max to get that static sag you need & take out some tire pressure! That will for sure make a difference! The roads around here can be awful so i fight the same thing. If you have been to the softest setting with no relief that should tell you tires are all thats left. 29-30 psi in the rear is absolutely plenty! Some run a lot less than that, youll have to experiment & see what you like. If you're at 36 & you ride a few hours you may be at 40psi or even more which would be a hard tire. Hope this can help you & you get it straightened out. If you don't believe me just listen to what this guy says about tires & pressure, anyone that knows will say the same! Good luck, ride safe!

[@mentallyderanged9169]

Good info, that’s why I always check cold and hot tire pressure. It gives you a good reference of a starting point, if do it a lot you will know the about start pressure. I street ride and if its 95 degrees out side I know to set cold tires at around 28, when I ride I know it will end up around 35-36. Just s trick a buddy taught me many moons ago.

Start in the middle and work either direction to find your sweet spot. A balanced bike would be something like 30mm in the front and 30mm in the rear for street. From there you can try some different settings to find what works best for you.

[@robertking1032]

I understand what is all about but as for me I am not going on track and I do not need a specific set-up for a specific track, what I will like to know what is the balanced set-up and what this set-up of sag will do to my driving? Can I have some tips?

[@SlackerUSA]

For general street riding I would shoot for 30mm on both ends. It will allow the bike to do everything pretty good and be very predictable as opposed to a race setup that would be geared towards a particular track and focus on doing one or two things extremely well and sacrificing in other areas.

[@robertking1032]

@@SlackerUSA ..thanx, you got exactly my point but 30mm on front is not too much soft? As far as I understood should be less than back, let say 30mm back, 20mm front, but what I also will like to understand more, other than compression and dumping (which are essential the most) how the bike will react on front with the 20 or 30 mm sag? How the back will react with 30 or 20mm sag? I get how the bike work in breaking and acceleration but how it effect it?

[@SlackerUSA]

@@robertking1032 It is a matter of what you like but generally I would start flat like 30 on both ends or 25 on both ends. To adjust the stiffness, that is all dampers, sag set the bikes posture and you do not use the springs to adjust the stiffness or prevent bottoming typically. As far as balance, having the front lower than the rear will make it turn sharper but be less stable at speed. If the rear sits lower it will be more stable at speed but will not steer very well. Racers make a compromise for turn or speed, for typical street riders you want a balanced, flat bike typically. The best way to find out is set it up and try tweaking it to find what you like. No rider is the same;-)

[@Striple]

I was wondering, if I want to measure the dynamic sag for my pre load, do I have to worry about the compression settings, because if there is a lot of compression rebound, the results I measure will be different from the results with no compression rebound, I suppose.

[@SlackerUSA]

I say it is always good to double check it if you make any major damper adjustments as it will affect where it settles;-)

[@lawrenceblah1563]

if I were to aim 30mm of sag for both static and rider sag. The measurement would be 60mm of sag with the suspension fully extended to with the rider on it. Correct?

[@SlackerUSA]

I think you are looking at it wrong. Static sag will only be around 10mm and the rider sag includes that number actually since the bike will just be compressed further when the rider mounts it. Static is measured with the bike under its own weight, and the rider sag is measured with the rider mounted. If you were to adjust to 30mm rider sag in addition to the 10mm static measurement, you would be running 40mm and will be way off track. Does this make sense?

[@lawrenceblah1563]

@@SlackerUSA so when I set up my sag I would just measure from suspension fully extended to with me on it? Right?

[@SlackerUSA]

Hi Kevin, it is Johny with Motool. It is hard to say not knowing what the rider sag is. Typically this would mean that the spring is too soft and it took a ton of preload to hold the rider up to get a decent rider sag number. Do you know what your rider sag number is or did the just preload the shock and send you on your way?

[@kevinmill7965]

@@SlackerUSA rider sag set approx 20mm

[@SlackerUSA]

@@kevinmill7965 Looks like the spring is way too tight. I would think the bike would be pretty unstable at speed and overall busy. Once you do this you will likely see 8-10mm in static sag. You should be somewhere between 25-30mm with the rider mounted. 30mm would be a great starting point front and rear for a basic street setup and you can tweak it from there for better steering or better stability at speed to see what works best for you for the riding conditions;-)

[@SlackerUSA]

You need to start with the tool at zero with the suspension unloaded. I know Dave starts with the tool at zero with the bike under it's own weight here, but he likes to add and subtract and it is not necessary. With the bike under it's own weight, simply put the tool in auto zero and lift the bike until the suspension tops out. Then all your measurements are in real-time. By the sounds of it you likely have way too much sag and are seeing a static of 26mm plus 25mm (51mm) you are reading when you sit on it. Make sure the tool is zeroed out with the suspension fully unloaded and then let me know what the measurements are;-)

[@DylanGSXR]

@@SlackerUSA fantastic , I've now got a static sag of 10mm ( slacker zeroed out bike upright and me lifting the rear end ). after some adjustments and when I'm on the bike with it under my weight I've got 28mm ( bike upright and slacker zeroed out and then me on it ).

@@DylanGSXR You are right on the money! No need to add, this is showing you 10mm with the bike under it's own weight and 28mm with you mounted. No need for math as it is measuring from where the shock topped out when you placed it in auto zero. Good work;-)

Shouldn't there be wood or something raising the rear wheel off the ground, the same amount as that blue thing raises the front? With just the front wheel elevated like that, wouldn't the rear behave like it's heavier then it actually is? And should suspension tuning be done with a full tank of gas, or half?

Great question, It is a Baxley stand and might throw it off like 1mm but if you always use the stand it really doesn't matter because it is already considered in the setup you have picked. Consistency is key so always have a full tank of gas, wear all your gear, use the same stand, sit in the same place and do it on level ground.

[@SlackerUSA]

[@DumbledoreMcCracken]

When accelerating, more than the maximum weight will be in the back (more than maximum sag),

[@muntee33]

DumbledoreMcCracken Of course the weight will transfer rearwards when accelerating.... But your concept of ‘maximum’ is slightly incorrect. (Half the trick is moving body weight, not only side to side but forwards and backwards to achieve the desired balance and grip required.) Sag is not a measure of suspensions rate and range of ‘movement’. Its a measurement of the springs percentage of compression with the riders mass and the bikes sprung mass (entire mass that is resting ‘on’ the spring. Ie; the mass of the wheel, swingarm, brake calliper etc etc are not included in the bikes sprung mass.)

For street run the same number on both ends and for a track run less sag in the rear to make it more aggressive. Feel free to hit up Dave on his channel;-)

[@dddon513]

I'm surprised this gizmo doesn't use a laser and a little mirror for measuring and then have it broadcast results to a phone app. Strings seem inelegant and prone to needing recalibration perhaps.

[@SlackerUSA]

Great idea. I actually started with laser and then ultrasound. The problem is that you cannot keep them pointed at a fixed position on the body as the axle rotates and they are very susceptible to light interference from sunlight so it never gave a stable or accurate reading I could trust, it was a similar situation with ultrasound. The lasers are also horribly expensive, like $600.0 just for a good one. The retractable cable was actually key to meking it super accurate while keeping it affordable. Inelegant maybe, but also beautiful in it's simplicity after all of the testing was done;-)

[@kasperhvid3218]

Well, what you can do is: There is probably a spacer on top of the springs inside your front forks. Have a machinist create pairs of spacers like the stock one but in decreasing lengths. This way you can adjust the preload on your front forks also!

[@heykat18]

Thanks

[@nicholascherry5962]

All I could think the whole video is that's a good looking bike

[@massgass9131]

Dave likes electronic beats... 11:46 "we know the static is 24" HEEYYY!!

[@strrider8474]

Do anyone got the coupon code?

[@SlackerUSA]

Just enter code 20off below the cart and hit "Apply" before you head to checkout;-)

[@zEver-bLack]

5:25 I know Dave is world renowned and all, but I'm not sure if everyone would be able to determine whether the bike is "topped out" while lifting 400 pounds of it with their hands XD

[@SlackerUSA]

Actually it is pretty easy to feel it if you have the strength to lift it. For the fork you could always use a head lift stand or a side stand or buddy will do;-)

[@raydavison2972]

Nice vid, that Motool is new to me so I need to see if it's available in the UK. Lose the music though, it irritates and reduces the ability to focus on the tech being provided.

[@SlackerUSA]

Thanks for the input, we will keep it in mind for the next vid. Also, we don't have much presence over there but we do ship to the UK. If you are interested, shoot me an email and I can get you a free shipping coupon code- [e-mail]

[@HelloJamesBond]

motool thought the music was fine

[@PMitchell106]

13:48, Why you gotta put that kind of pressure on me, Dave? 😰

[@johnny_123b]

Why is only one side on stand, but trying to measure difference between front and back...

[@SlackerUSA]

Because you have to sit on the bike to take the measurement. It is just there to hold the bike up not keep it off the ground.

[@johnny_123b]

motool Yeah but it does lift it for few milimeters, which is significat enough to be noticeable in measurements. Why weren't both rear and front stand used?

[@SlackerUSA]

it is not significant honestly, Dave is hands down the best tuner I have ever met and he is super picky. If he thought it was an issue, he wouldn't use the Baxley stand. The front tire being 3mm off the ground does not change the measurement by 3mm, it is a fraction of a millimeter. If you feel it is necessary to use two stands that is fine but it is overkill if you ask me. We are measuring in millimeters not tenths or hundredths. The key is to always do it the same and to know your numbers.

[@johnny_123b]

motool Okay thanks :)

[@SDevante]

Dave just cost me $175 lol

[@SlackerUSA]

He seems to have a way of doing that:)

[@brentfrank7012]

So that tool is $175?

[@rawpower1924]

I'm riding a 2006 kawasaki 636

[@TheSixYardBox]

Didn't understand half of that. You basically just maxed out the preload. And when you did the front it visibly got lower but you said it was taller...proper confusing

[@Ad-my9kg]

Hi Simon .Not sure why you think the front of the bike got lower. I looked and could not see any movement, but you wont really see a 6 mm change from that distance, in either direction. Adding preload means you are compressing the spring and that the bike's own weight will therefore have less of an effect on the travel of the suspension - hence it sits higher when preload is added. Suspension only has a certain amount of travel so you want the weight of the bike, and you, to only take up a certain amount of that travel. (I'm not an expert, but hope that helps)

[@HelloJamesBond]

WhySoSerious ? Hi there, if you’re compressing the spring you’re making it shorter, by definition. So I don’t understand how this makes the front end sit up unless you’re actually putting tension into the spring to make it stiffer which would make it taller.

[@shawoo]

Can u just adjust my bike for Me please?

[@zacstunden4291]

He did my gsxr750 a couple years ago. Would recommend highly. He was doing tours around everywhere and I was lucky enough he was close to mine and yeah. An awesome set up

[@muntee33]

Make a note how many clicks things turn for before stopping, write these numbers down and return everything back to where they were. (This is your ‘base’ setting you can always return too if you get it wrong. Now, find out what adjustments your bikes suspension has and go watch more videos that explains why and how these adjustments should be made, and how the various adjustments should be balanced against each other. Then have a try.... All you need is, •a tape measure, •a small flat head screw driver and •a ‘C-spanner’ for your model of bike, which are cheap and your local bike dealership will be able to supply you. •And an extra set of hands to help balance your bike while you sit on it. Just leave any bolts alone unless you have a torque spanner and a manual for servicing your bike.

[@vladzero391]

wait a second...wat? 159$ for electronic measuring tape O_o What about something similar to Quarq ShockWiz?

[@SlackerUSA]

Definitely not just a tape measure. It reads everything in real-time and you can use your phone as a remote display and also record all of your measurements into your setup notes in the app. Shockwiz is a totally different concept and only works on air suspension and does not measure anything. I see some value in measuring at the shock but it is more accurate measuring at the axle and it gives you way more granularity for adjustment. I do plan on another product in the MTB space that is probably more in line with your thinking but it is a couple years out still.

[@dougiequick1]

So dealers have no right to offer test rides? OR to allow a new buyer to ride his new unmeasured sag motorcycle home? Just saying is all Dave's "no right to ride the bike" seems just a tad bit fanatatical? Maybe should be somehow rephrased (6 years later lol) as "no right to expect an unmeasured motorcycle to be right or as safe as it should be to ride".....something along those lines perhaps...its what I dont care for about Dave....a bit hard to take sometimes

[@search4orlife]

Not confusing at all

[@granite676]

Great vid , 👍😉 just lose the whiny background music 🙄

[@montanaheaventush]

missed a trick not have an affiliate to that tool lol

[@genoa49]

My head exploded
