You do excellent work. Sorry to blog a bit here, but I'm just so elated that people around the world are teaching the benefits of proper suspension setups. You're on the cutting edge. As a linguistic point of clarification, in the US etc, "free sag" is sometimes called "static sag"; interchangeable terms. What you call "ride height" is called "rider sag". Free Sag + Rider Sag = "Total Sag". In the US etc, "Ride Height" is the distance between the shock's frame mount, and its swing arm mount or lower linkage mount (depending on bike construction). Often this just happens to be the length of the shock from eye to eye. Obviously you have another term for this. Just know that if you're watching or reading Western sourced material, ride height means something different (in Britain "shag" means something totally different than it means in the US). Some stock shocks have ride height adjusters, and most aftermarket shocks have them (usually a nut with lock nut at the base). If your shock does not have an adjuster you can usually add ride height (increase the distance between the frame mount and swing arm / linkage mount) by shimming the upper mount. Ride Height adjustment is used to obtain the correct swing arm angle. Rarely, very rarely, does a bike have too much swing arm angle stock off the showroom floor. They usually do not have enough. For example, the vast majority of riders find the 2008-16 Yamaha R6 handles better with a 5 to 7mm shim or washer stack atop the upper shock mount. This increases the swing arm angle. You can mimmic a ride height change by adding or removing preload because doing so will change where the bike rides in the overall stroke of the shock. If you add preload the bike will spend more time higher in the stroke as if you had increased the shock length. But it will also create other handling issues. Sometimes there is a net benefit. But the real fix is to change the ride height, or the term you have for that.

Thanks a lot boys.. This vid helped me with my Sb-3 setting on my Aerox. Greetings from Singapore

[@jampiserapah]

Damn, love these tutorials! Teaches me a lot!

[@dadsonion5292]

Clear and easy to follow instructions thank you.

[@game-passakorn]

Thanks Guys, excellent, very easy to understand.

[@AshrafHalib]

I read in the RCB VD manual, recommended measures for Ride Height is: Rear: 20-25 mm Front: 25-30 mm Thats why they follow the 20 mm at final calculation.

[@taikotayar2064]

Bro dah setting ke?

[@muhammadamirulaimanmashudi1752]

Apa maksud front tu? Ni setting untuk absorber kan?

[@centrifugal819]

which means each shock absorber brand has their own manual mentioned the setting value ?

[@nadzmiao]

very insightful! thanks for the video 👍

[@broderp]

Very clearly explained. Thank you! Please do a video explaining how the preload impacts riding and performace.

[@rentakangkasa5676]

Thank you boss it’s so much useful

[@KK-bx9xr]

@2:38 You're supposed to stiffen the spring if the value is above 8mm and soften the spring load when below 5mm.

[@arai6147]

Exactly i was like what math did he use to come to that conclusion

[@rolandderoxas664]

Yes you are totally correct..

[@vincecarreon7264]

I thought I was the only one who noticed this haha!

[@mydungtathi5913]

Very good and funny videos bring a great sense of entertainment!

Dam excellent video

[@yenvhs5943]

thank you!

[@ljgarrison6910]

Nice video, I have a zzr with a pogo issue at the moment, mainly at speed - also struggles to turn in. Preload is 1/3 wound up, i'm a 130kg man - perhaps I need less to allow full travel as with potholes, the bike skates along and doesn't grip atall. Front forks standard, rear shock EMC sports shock. I'm at a loss!

[@chenakerhamza]

Thinks for profetional job

[@WanSelarChannel]

GOOD INFO

[@FreqyBiker]

Thank you, very easy to understand. How do check the unloaded/free sag without centre stand?

[@okboomer1241]

Great introductory tutorial, particularly the concept that the same preload setting will not work for every rider weight. Next, demonstrate what must be done when you add preload to get the correct "ride height" but in doing so you lose all your "free sag" (it goes to 0mm). Conversely, what to do when you remove preload to get the correct "ride height" but now have too much "free sag".

[@vinshinity]

When u need to remove the preload to get the right sag you nid a softer spring.

[@okboomer1241]

@@vinshinity Excellent. You're close. To be more precise, when you must remove ALL the preload to get the correct sag you DEFINITELY need a softer spring. Conversely, you definitely need a stiffer spring when you must ADD all the preload to get the correct sag. Ideally you want to achieve the correct sag (30-40mm street, 20-30mm track) somewhere in the middle third of the total adjustable range. This provides plenty of room to adjust preload to rider ability and road conditions based on travel used. Sag is just a place to start the tuning process, not the end. Ultimately, the amount of travel a rider uses determines whether the spring is too stiff or soft. A light rider who brakes hard all the time might use the same fork spring as a heavy rider who coasts more than brakes. The same rider on a liter bike will need a stiffer shock spring than on a single cylinder bike to handle the horse power even if both bikes weigh the same. For street and track day purposes. Pro racing has many other factors that determine spring rate. Sag is never a factor for them.

[@aguskarismawan7484]

Please give me advice for the correct setting rcb sb2 on my nmax?

[@shahrilhelmy5708]

Good

[@johnedwardmcgladdery5071]

You said the range was 25-30, and then adjusted it to 20.?

[@johna6968]

My first thought too

[@mari.bercerita]

From this we know that those type of suspension is too stiff for the rider. While it's already adjusted to the lowest level available. Hahaha

[@landauadventures5157]

Great info guys. Is this applicable to adventure motorbikes as well?

[@dmzsniper]

For a 2018 Ninja 400 do you have to do both (free sag and with ride height)? And do you know the recommended settings for it?

[@eddiehash51]

👍

[@markchristiantabang6659]

plottwist: the marker was permanent

[@aminor87]

After i got R1, then adjust the proload to get correct sag. just proceed to get R1 or need to measure again the R1?

[@sovannalong7585]

for bike that sometime ride two pp. how many between mm should adjust ?

[@2wentys7n]

What is the standard settings for Compression and rebound before adjusting the Pre-load?

[@abnerabaquita8800]

How or where you get the preload value of 25mm-30mm? Thanks

[@edwinalcarde5501]

is the free sag and ride height recommended value is the same foe all kind of bikes??

[@kreeztancruz7403]

He said the recommended range is 25-30mm but when he got 20 it's still within the range.

[@freymardavebernardo3256]

You said that the recommended value is ranging from 25mm-30mm but you measured only 20mm in aerox dual suspension? Is 20mm acceptable or not ? From philippines thankyou in advance :)

[@lq7981]

Damn they not reply u in 2 years! Haha so funny ah ini apek.

[@bongky8641]

great tutorial video. very well explained. just a bit query on the last part of the video, the recommend value as you have said is 25 to 30mm. but why did you stop on the 20mm mark?

[@erwinllauderes432]

Correct mo if im wrong maybe he measure by 20mm only just because its a dual shock compare to 25 mm which is mono shock only..

[@bienignatiuscabigas4007]

What if im not using a genuine swing-arm is it still standard measurement?

[@charliedawnsisneros5260]

Is crf 150 mono can be adjusted to have smoother play?

[@BboyEMC]

Is the calculation the same in front shock? Considering im using monoshock in both front and rear?

[@aimanshafiq9582]

what about sport naked bike like mt15 ?how to measure it ? does the recommend settings same like a moped ?

[@amirhamzah3652]

How about setting preload in singgle shock matic?

[@RVnelleville]

How about for mono shock sb-3

[@syedsyclone6827]

25mm - 30mm tetiba 20mm ok plak??. Edit balik wo!~~

[@toadcrew3429]

Pelik kan..heheheh

[@widiarnoahmad]

Hahah

[@yblyong6104]

You've adjusted Arip's suspection height is 20mm which is not in the recommended height. (06:26) As you said the recommended height is 25mm-30mm. (05:43) *Correct me if I'm wrong

[@zizhdizzabagus456]

He confused it with front fork recomendations

can you make video on nmax there are only few who can do this on philippines so hard to find tuner on shock

[@Isjnsjs]

if i am mostly ridiing with pillion, will i.need to.adjust the preload with a pillion? or i only adjust according to myself as a single rider and onli adjust the compression

[@taikotayar2064]

Ejas sekali dgn pembonceng

[@mreza2364]

Jadi yang dipakai itu free SAG atau ride height nya ?

[@abdulmateen5635]

Hi... want to ask if want to adjust the preload,, is there anyway to adjust ourselves without any help? Because i see this video someone sit on the bike and other person dping the measurement.

[@jayaralcaide5848]

Is it normal that the spring can move up and down after adjustment ? Does it mean it is adjusted so it moves ups and down ?

[@campurchannel4284]

If the shock matic only uses 1 shock on the left side, is it the same as the mono shock in the way it is measured?

Bos, nice explanation. But in dual shock system, you said earlier the recommended range is 25-30mm but after adjustment, u got 20mm and you mention that is recommended value. Which ome is correct?

[@CZERcrew]

Correct, mana 1 yg betul tu 🤣

[@gilbert7541]

got a db2 ..but no one knw how to do this adjustment for me.

[@DebanjanDuttcambridge]

What is the recommmended range based out of. Is it just your experience with bikes or is it backed by some studies ?

[@mohdkarizayunan4387]

can go there and help to setting spring preload ? i dont know how to setting because sometimes using for 1 person sometimes 2 person . before this im using soft spring its very superb.. but when i change to hard spring its like im riding horse .. hahaha ..

[@yosiska]

You mentioned preload *rec'd preload is 25 - 30.* I have the SB2 n in the instructions book, *the rec'd value for the rear suspension is 20 - 25.* Which one is the correct one?

[@hannannajmi2955]

How about SB1?

[@datnguyen7494]

I really suggest you should get a different color lip ring; it looks like a ward from afar

[@mystickerco]

guys, for ride height, recommended height for rear is 20-25mm or 25-30mm as stated in video? Based in your manual, 25-30mm is a recommended for FRONT, not rear. Correct me if i wrong.tq

[@eddytanjielong]

Hi! Can I just query, if my seat vibrates like crazy when I ride, which setting should I adjust? Spring preload, rebound or compression? It vibrates at certain speeds when I ride. Appreciate any help given.

[@debdeepdutta2148]

Where to get the screwdriver to loosen the screw and adjust the preload?

[@tbr27]

“If you get a value above 8mm, loosen up the shocks by turning the adjusters anti-clockwise” Shouldn’t it be tighten up the preload by turning it clockwise? If the difference between the 2 reading is high, it means the preload is too soft.

[@mohamedirfan318]

He say opposite lah. I did what he say from 1mm now my difference is 0mm. Haiyo must loosen turn anti clockwise to get higher mm reading.

[@rodney2825]

Does pillion rider matter when making adjustments?

[@xtremegenerationjack]

Ofcourse.. if you have a pillion rider, then your shock settings will majoring differ.

I buy 1 new set of rcb db2 line plus premium black, i read the "suspension user manual" it said on the "ride height" is rear should be 20-25mm and front sus. Should be 25-30mm, and on this video you said on this rear suspension tutorial that it should be 25-30 mm when the rider is on, i don't know who to follow your instruction or the user manual instruction.

[@roderickperez1279]

Such a nice content, however the background sound is so annoying. Is the sound necessary on your tutorial or any tutorial?

[@nikobensien4135]

Your 2nd measurement with the 60kg guy resulted in 20mm difference R1 to R3...on the first measurement you said the correct value is between 25-30mm... if your not simply mistaken it makes no sense to me. Cheers

[@wildbad]

You refer to "reccomended value" but neglect to mention where this value comes from.
