How To Adjust Suspension on a Dirtbike (Compression and Rebound)

[@chadrides914]

Hands down. Without a doubt. The single BEST instructional I’ve ever seen or read on suspension basics.

[@GRmotors]

Thanks!

@@GRmotors your welcome Sir 👍

[@bradmohre5599]

Awesome video man. You gave all the needed basic information without giving too much and making it confusing. Thank you.

[@krazykurt1536]

You explained it much better than other videos, thanks

[@GRmotors]

No problem!

[@justharryjohnson7250]

Thank you. The best, straight to the point simple explanation of every adjustment.

[@GRmotors]

No problem

[@redriders7149]

Thank you, your explanation was simple and i finally fully understand the adjustments.

[@GRmotors]

No problem!

[@stevieb68]

Great video, I sent this to a friend to explain it better then I can even with a helping video to add. Keep up with the videos you did a great job.

[@GRmotors]

Thanks!

[@kevinstover1986]

Great job bud , I am knew to riding a crf 450 rx and it really seems very stiff, I can feel every gravel what is a good tire pressure for off road

[@GRmotors]

10-12 psi. Usually more in the front than in the back. I run 12 in the front and 11 in the back. I wouldn’t get much lower than 10 though

[@Markonacr250r]

Best video out of 3 videos. Good job

[@GRmotors]

Thank you

[@trentfinnessey5770]

I'm happy I found this I had to do this on my kx250f because I'm about 5'11

[@commantrosexetlos4700]

amazing video that acctually shows us how its done than talk what they do

[@furocity]

Basic and to the point. Great video

[@jeffswanson5097]

Nice, clear, and to the point. Thanks!

[@bdm7m458]

I have a CRF450R 2021 which I got from overseas, the Suspension was soft and the rebound was way too fast. This should help out a lot.

[@carolsnider2917]

very good video- explained well so a dummy can understand

[@chiefbrody2173]

Nice vid thanks bud. Just did mine. ‘08 ripper

[@GRmotors]

No problem man

[@thumpertorque_]

I'm learning this for street riding on my DRZ400SM. I'm planning on riding with a passenger and to compensate for the extra weight, should I stiffen up the high and low speed compression? Also should I just stiffen the rear or the front too? Thanks.

[@GRmotors]

Yes stiffen high and low. And stiffen front and back

[@nuyeezy516]

Great post! Incredibly helpful🙂🙂🙂

[@GRmotors]

Thanks!

[@fxdwings]

Is it based off your weight and riding style? I do woods and hard pack. No motorcross. 240lbs what do you recommend? TIA

[@GRmotors]

What type of bike do you have?

[@fxdwings]

@@GRmotors 2009 crf450f. Thanks

[@GRmotors]

It’s probably close to where it needs to be if the suspension is stock and settings haven’t been changed. But if it’s used the first step would be to get the suspension rebuilt to make sure it’s performing correctly and then adjust from there. Woods riding typically likes soft settings and slower rebound because of how rough it is

[@fxdwings]

@@GRmotors thanks for you input. Fantastic video

[@GRmotors]

Thank you 👍🏻

[@normannorman2436]

Excellent video and explanation

[@deanhelvey6021]

You explained this very well, it helped a lot😎

[@GRmotors]

Glad it helped!

[@themotocrosslounge8697]

do you bleed the air out before or after you adjust the clicker ?

[@GRmotors]

It doesn’t matter, you’re adjusting how open a valve is inside of the fork to allow oil flow. The air builds up on top so it doesn’t affect it in any way.

[@themotocrosslounge8697]

@@GRmotors thanks for the feedback, my forks won’t even compress it’s so bad and killing my arms

[@AnotherCogTX]

What's the other screw on the top of the fork for?

[@GRmotors]

Towards the top of the cap?

[@AnotherCogTX]

Just bought a used dirt bike. I've never had one before. But the top of my fork has two screws. One in the middle, and one off to the side. No letters or anything next to that one. Just looked at it again. I think it has to do with assembly. One was loose so it made me think it was an adjustment screw.

[@GRmotors]

@AnotherCogTX What bike is it?

[@AnotherCogTX]

@@GRmotors yz250 with aftermarket shocks. I figured it out. Air bleed screw. Your bike in the video has push button bleed valves it looks like.

[@GRmotors]

@AnotherCogTX yeah I was about to saw that’s probably what they are

[@gbw1973]

Great video,thanks mate.

[@motocbrjkallen7178]

So I'm writing a CR85 and it's too soft on the rear shock how do I stiffen it?

[@GRmotors]

Should have a compression adjustment on it the same as the 450 in this video

[@NiklasRuud]

So to adjust front forks you don’t need go all in and count backwards the clicks

[@GRmotors]

You can, that will give you a better idea of where it is

[@Zams76k]

I’m late man but this video is fucking great

[@GRmotors]

Appreciate it!

[@madamejesus6591]

Thanks very much man much appreciated great vid very helpful. Peace.

[@kengbunsai5713]

Can crf 250l front suspensions adjustable? Can you show me? It is 2021 Honda crf

[@GRmotors]

I would think so but I’m not 100%

[@smbmxdirt3427]

Great video thanks bro!

[@Isaiahstetson]

I can’t find where my rebound is, it’s not under the leg of my fork to the right or on the top pls help

[@GRmotors]

What kind of Dirtbike do you have?

[@Isaiahstetson]

I found it and just set everything up to base line, thanks for responding tho

[@GRmotors]

@@Isaiahstetson awesome man

[@OKC_forreels]

Is there a way to lower the bike?

[@ashleymillet]

Look for soupys lowering link

[@Niconico_t]

Will this change ride height

[@GRmotors]

Not much, like millimeters

[@rossokeefe9268]

What would be the factory setting on these..how many clicks?

[@GRmotors]

Shoot man, I’d have to find an owners manual. Been years since I’ve owned that bike

[@rossokeefe9268]

@GRmotors I bought the bike used..alot of mods..seems like more towards street..had a 14/48 gear set...changing back to a 13/51...just seems really stiff like riding a jackhammer..

[@GRmotors]

@rossokeefe9268 May be sprung or valved too stiff for your weight. But for the clickers I would run the compression and rebound all the way in and then all the way out and see how many clicks there is. And then go half way back in. Do that on front and back and ride it like that and see what it feels like. That will get you close to stock settings.

[@jettgriffith7216]

I have a kx250f, and the front shocks only have the adjustment screws on the left side, but not on the right... Do you know if am I missing parts or is it designed that way?

[@GRmotors]

What year is it?

[@jettgriffith7216]

GR.motors it’s a 2012

[@jettgriffith7216]

GR.motors I did some research and I think they’re sff shocks or whatever, but I still don’t understand how I’m supposed to adjust them with only one side

[@GRmotors]

Yeah it’s the separate function fork. So only one fork has a spring in it and the other controls your dampening. So the one with the controls you see on top is your Compression (stiffness) adjustments, and the same fork has the rebound (how fast or slow the fork returns to extended position after you hit a bump or jump) adjustment on the bottom of it. The other fork has a blue hex nut on top, it turns. It adjusts the preload (how high or low the front of the bike sits)

[@jettgriffith7216]

GR.motors so if I adjust just one side it’ll do the same for the other side? I don’t want to have my two forks on separate settings

[@adzk75]

Awesome! Thanks! 🤙🏼

[@GRmotors]

No problem!

[@TheDesertsweeper]

1:50 air-bleeders - you should only do this with the bike on a stand, not sitting on the deck

[@GRmotors]

Correct, I got ahead of myself on that one

[@powayimports4175]

So to be clear the air should be bled after adjustments are made? In either direction?? Sorry new to this stuff.

[@GRmotors]

Air will build up anytime you ride the bike, just bleed the air after you ride

[@anthonyeskins791]

Im pretty sure the springs are air springs and they are supposed to be pumped up to 30-32psi.

[@GRmotors]

Krafte Tuning Ltd. No they are Springs. Air forks were not on the bikes until 2013

[@giorgakos-]

For slow rebound is H or S ??

[@novahoodanas976]

i tried to adjust those rebound and compresion screws but nothing changed., is there a problem with my usd fork? if there is, what might it be?

[@GRmotors]

How many clicks did you adjust? And what bike do you have?

[@novahoodanas976]

GR.motors i turned the screw counterclockwise 10 clicks both conpresion and rebound but nothing changed., i have a kxf250 fork

[@oo0Spyder0oo]

If your settings are screwed up, how do you return to standard factory setup? I can hardly feel or hear the clicks so I have no idea where my factory setup should be to begin fine tuning. Cheers

[@GRmotors]

Sometimes you can find the factory settings in the bikes owner manual or online. If you can't find them I've heard the best thing to do is turn the screw all the way in or out and then go all the way the opposite way. Like if you turned it all the way in then go all the way back out and count how many clicks you hear. Once you know the number, say it clicks ten times, then start in the middle which would be 5 and work from there. Just don't over torque the screw, once you feel resistance don't force it or you could tear it up.

[@oo0Spyder0oo]

Thanks a bunch, I can feel it go a little loose where it would probably be a click, sometimes it's a click and others you can't hear at all so I'm feeling my way around. My manual states 10 clicks out is the standard setting, it was just knowing when I had any clicks, I think I may have it ok now, feels like every third of a turn sets of a click, does this sound right?

[@GRmotors]

Yeah that's right! Sometimes you won't hear the click but you'll feel it and yeah a 3rd of a turn is about right

[@oo0Spyder0oo]

Good one, much appreciated. All the best.

[@ashtonallen9193]

GR.motors o

[@hectoreves4375]

What’s the stock setting for the clickers

[@GRmotors]

Should be able to find online, usually a good starting point is half way out from all the way in. So if you have 12 clicks, set it at 6 and go from there

[@i_taco_every_rail951]

My crf150r has no click it’s just like a normal bolt what do I do then

[@GRmotors]

It has a nut in a hex shape?

[@i_taco_every_rail951]

GR.motors no it’s round and uses a flat head screw driver

[@GRmotors]

Ok, it probably goes by “turns” instead of “clicks”. So I would turn it two full turns and see what difference it makes and then if you can’t feel a difference go a few more turns until you are feel difference and then you can decide which way you want to go with it. Typically turning right will make it stiffer and left will make it softer

[@daltoncerella9681]

Thank you

[@gtavtheavengergunnerlegend3340]
